Atoms Trapped with Light Behave Like a Dissipative Quantum System

A team of researchers from Japan experimentally realize, for the first time, a dissipative, parity-time symmetric, many-body quantum system from ultracold atoms trapped in an optical lattice.

A Quantum Description of Physical Systems with Non-real Energies

While quantum systems are traditionally described by Hermitian Hamiltonians, the formalism is extendable to a non-Hermitian description for systems that are dissipative or obey parity-time symmetry.
