" Nonlinear Quantum Liquids in One Dimension''
The conventional description of one-dimensional quantum fluids is based
on the Luttinger liquid theory. In that theory, the true energy-momentum
relation of particles making up the fluid is replaced by a linear one.
This simplification is crucial for the theory, and abandoning it has
proven to be difficult. The talk describes a breakthrough which allowed
one to circumvent the difficulty. The new theory describes dynamic
responses of a fluid consisting of particles with a generic spectrum. It
is applicable to a diverse group of systems, including, for example,
electrons in quantum wires and cold atomic gases in one-dimensional traps.
