Some 50 Bangladeshi workers representing 270 victims lodged a police report and held a press conference in Kuala Lumpur on Sunday. — Photo: New Straits TimesA company is believed to have cheated 270 Bangadeshi workers of more than RM2 million and taken their passports, reports New Straits Times.The workers had reportedly approached the company to help them find jobs and apply to the immigration department’s rehiring programme for work permits.Some 50 Bangladeshi workers representing the 270 victims lodged a police report and held a press conference in Kuala Lumpur on Sunday, said the newspaper.The Bangladesh workers were said to have asked the authorities to take action against the company and retrieve their passports.One of the victims, Mohamad Alagir, was quoted to have said that most of them started dealing with the company in March last year.He was said to have alleged that the company had asked them to hand over their passports and RM8,000 per head for the application.“The company promised to help us look for jobs and apply for a working permit from the immigration department. However, it is more than a year now and nothing has happened.”According to New Straits Times, Alagir said he and his friends from Johor, Kelantan, Pahang, Selangor, Perak, Penang, Melaka and Negri Sembilan had lodged police reports and filed complaints with the Bangladesh high commission.He told the media that they were living in fear because they did not have their passports and that the company had refused to return their passports.The newspaper quoted another victim, Imran Haz Uzzal, as saying that most of them had worked in Malaysia for more than five years and had entered the country legally through other agents.He was quoted to have said that they started having problems when they approached a company in Bandar Baru Bangi to help them get jobs and renew their working permits.“We hope the authorities will intervene and help us.”
A newspaper stand shows a copy of today’s Evening Standard, with the front page story relating to British Prime Minister Theresa May’s triggering of Article 50 of the Lisbon Treaty to begin the process of Britain’s withdrawal from the European Union (EU), in London. Photo: AFPBritain launched the historic process of leaving the EU on Wednesday, saying there was “no turning back”, but its European partners were quick to warn of the difficult path ahead.Nine months after the stunning vote for Brexit, Prime Minister Theresa May gave EU President Donald Tusk formal notification of Britain’s intention to withdraw from the 28-nation bloc.The unprecedented move, just days after the EU celebrated its 60th birthday, leaves Britain deeply divided and has thrown a question mark over the future of the alliance.“This is an historic moment from which there can be no turning back,” May told MPs, to cheers from members of her ruling Conservative party.British ambassador Tim Barrow delivered the letter to Tusk triggering Article 50 of the EU’s Lisbon Treaty, starting the two-year countdown to Brexit.“We already miss you,” Tusk said in Brussels.But French President Francois Hollande struck a tough tone, warning that Brexit would be “economically painful” for Britain, the first country to leave the alliance.German Chancellor Angela Merkel also rebuffed May’s call for negotiations on Britain’s withdrawal to run alongside talks on a future trade agreement.Britain intends to leave Europe’s single market in order to control migration, but is hopeful a new trade deal can be struck before it leaves the EU by the latest at midnight on 29 March 2019.Merkel said however that the divorce must come first—including tough talks on Britain’s financial contributions, as well as immigration.“Only when this question is dealt with, can we, hopefully soon after, begin talking about our future relationship,” she said in Berlin.The EU, which was forged from the ashes of World War II, is determined the Brexit deal will not encourage other countries to follow Britain out of the door.May’s six-page letter struck a conciliatory tone and called for a “deep and special partnership” with the bloc, which Britain joined in 1973.But some commentators saw a threat in her emphasis on the importance of Britain’s security ties.She warned that failure to reach a new trade agreement would mean “cooperation in the fight against crime and terrorism would be weakened”.‘Damage control’Tusk is expected to issue draft guidelines for the negotiations on Friday, but the leaders of the other 27 EU nations will not meet until 29 April to confirm their joint approach.The bloc’s priority is to maintain unity as it faces the departure of one of its largest members, against a backdrop of crises involving migration, terrorism and the rise of populism.A spokesman for US President Donald Trump, who has described the Brexit vote as “smart”, said: “We want the UK to remain a strong leader in Europe.”But May is battling to keep her divided nation together.The Brexit vote was only won by a narrow 52-48 margin and Scotland’s nationalist government is now calling for a fresh referendum on independence.May has said “now is not the time”, even if Scotland—and Northern Ireland—voted overwhelmingly to stay in the EU, but were outvoted by England and Wales.In Edinburgh, 44-year-old computer consultant Mark Murphy said he had voted for Scotland to stay a part of Britain in a 2014 referendum but might now change his mind.Brexit was “probably the daftest thing we’ve done as a nation for my entire life”, he said.‘Implementation periods’As with many divorces, negotiations with the EU could rapidly turn nasty over money.The priority for Brussels is settling Britain’s outstanding bills, estimated at between 55 and 60 billion euros ($59-65 billion) — an early battle that could set the tone for the rest of the talks.Both sides are also keen to see a reduction in tensions in Northern Ireland, which will have the UK’s only hard border with the EU.Many business leaders are deeply concerned about May’s decision to leave Europe’s single market, a free trade area of 500 million people that represents Britain’s largest trading partner.The Brexit vote sent the pound plunging and there are fears of what will happen if negotiations end without a new trade agreement in place.The European Parliament’s chief negotiator, Guy Verhofstadt, said any transitional deal to work out the details of a trade agreement should be limited.“We propose three years,” he said.‘Dream come true’Both sides have said they want an early agreement over the post-Brexit status of more than three million European nationals living in Britain.May has said this will be conditional on a deal for the status of one million British expats in the EU.Nicolas Hatton, a Frenchman with a British wife who leads a grassroots campaign for EU expatriates, said he wanted a deal “so that we can get on with our lives”.Tens of thousands marched through London on Saturday demanding Britain stay in the EU, with one banner urging politicians to “stop this madness”.But others were elated that Brexit was finally under way.In Sunderland, a bastion of Brexit support in northeast England, former miner Tom Curras said: “I don’t believe that we should be dominated by other countries.”Nigel Farage, the founder of the anti-immigration UK Independence Party (UKIP) and a key player in the Brexit campaign, celebrated in a pub near parliament.“Today’s the day for me after 25 years of campaigning that the impossible dream came true,” he said—before a passerby heckled him as “a disgrace”.
Citation: Souping Up Superfluidity Calculations (2006, March 2) retrieved 18 August 2019 from https://phys.org/news/2006-03-souping-superfluidity.html “In quantum mechanics, very seldom do you solve exactly problems involving more than one particle,” explains Massimo Boninsegni, Canada Research Chair at the University of Alberta. Boninsegni and his colleagues, Nikolay Prokof’ev and Boris Svistunov, both at the University of Massachusetts, have found a way to work with quantum systems involving many interacting particles on a scale larger than ever attained before. Their creation, named worm algorithm, is a new approach to path integral Monte Carlo (PIMC) simulations, the only known exact general method in quantum mechanics. Superfluidity is among the most spectacular manifestations regarding the quantum behavior of matter on a macroscopic scale. Superfluids are liquids capable of flowing without resistance, a fascinating phenomenon not yet fully understood. In 2004, another state of particles on the quantum level, supersolids, was discovered. Supersolids act like superfluids (moving without resistance), but maintain the characteristics of crystalline solids. PIMC is the only known method that can afford the theoretical study of superfluidity, by allowing the simulation, on a computer, of realistic models of superfluids, and by providing exact estimates of key physical quantities, such as the superfluid density. This is where Boninsegni, Prokof’ev, and Svistunov come in. In a letter published in Physical Review Letters on February 23, they explain how their worm algorithm overcomes some of the limitations of PIMC, while still making use of its basic ideas. “If you look at what people were doing by PIMC last year, they were working with the same system sizes as 20 years ago,” Boninsegni tells PhysOrg.com. “It seemed impossible to go bigger. The fundamental approach had to be revisited.” Now, he says, it is possible to have results for systems with 100 times more particles, obtaining more accurate predictions for experimentally measurable quantities such as the superfluid transition temperature. Boninsegni continues, “If it was just about getting more accurate numbers, though, I wouldn’t be so excited. We’ve made it possible to do things that seemed out of reach just a year ago.”Some of these things include getting a better understanding of defects in solids or the presences of interfaces between two crystalline samples. In order to do that, it is necessary to have a model of a system large enough to show the complex interactions between many particles, and still have particles left over for the interface. The worm algorithm works by creating entanglement among the particles. This done by “cutting” particles, which Boninsegni explains are “much like strings or polymers that wiggle all over the place.” The polymer-like particles break up and reconnect with other particles in the system. The worm algorithm allows the particle ends to grow and shrink along a fictitious (“imaginary’’) timeline. They connect with and disconnect from other particles, but eventually the two loose ends reconnect. By the time the cut polymer finds itself back together, it has created a large permutation cycle. These cycles are crucial to capture the physics of superfluids. The algorithm was originally applied by Prokof’ev and Svistunov to lattice models of space. But a new set of research possibilities (including discovering a possible “superglass” state, in addition to the supersolid state) has emerged from the fact that this particular project has extended the worm algorithm to continuous space, and not just discrete space.Boninsegni explains that this is not a method of creating a “worm hole,” but rather a mathematical calculation that can better help us understand the underpinnings of our universe. Being able to work with multiple particles and larger, complex systems will open new doors into the possibilities presented by quantum mechanics.
