Huber and Ehud Altman<br/>We study a quantum quench in a system of two coupled one-dimensional tubes of interacting atoms. After the quench the system is out of equilibrium and oscillates between the tubes with a frequency determined by microscopic parameters. Despite the high energy at which the system is prepared we find a...<br/>[Phys. Rev. Lett. 103, 160402] Published Thu Oct 15, 2009 Sebastian D.
