Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The ...

The formulation of a general theory of transport in many-body systems is one of the challenging problems in theoretical physics. Unlike the Gibbs-Boltzmann framework for systems in equilibrium, there ...

(Nanowerk News) Wormholes play a key role in many science fiction films – often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely ...
