Workshop Addresses Recent Research on Quantum Chaos in Bose-Einstein Condensates
New research on the quantum version of the chaotic behavior of Bose-Einstein condensates will be discussed during the Workshop on Bose-Einstein Condensates and Quantum Chaos, to be held from March 30 to April 2, from 9 am to 5 pm, at the IEA’S Events Room.
The event is organized by IEA-USP's Unconventional Nuclear Astrophysics Research Group and will have the participation of physicists from Brazil, Russia, France, Israel and the United States. The workshop is free of charge and open to all interested parties. Registration is not required. The event will be held in English (without translation).
The group’s coordinator, Mahir Saleh Hussein, from USP’s Institute of Physics, explains that no system can achieve the lowest possible temperature (‑273.15 °C) and as a system approaches this temperature its atoms condense to form the so-called Bose-Einstein condensates, a new state of matter in which all the atoms (100 million, for instance) behave as if they were a single atom. These systems can display two types of behavior: orderly, with a predictable future; or, with a change of variables, chaotic, in which the future becomes unknown. The quantum version of this chaotic behavior is known as quantum chaos.
The event will be broadcast live on the web.
