* ABSTRACT
Solitons are reentering the experimental physics of quasi-1D electronic systems, from density waves to cold atoms, reviving old and posing new requests to the theory. Among them are problems of separation and reunification of the spin and the charge, fractional variable charges, instantonic processes of converting electrons into solitons, confinement of topological defects from symmetry reductions and higher space dimensionality, local dynamics of induced transformations among electronic phases. At the 1D level, the support comes from exact solutions for quasi-classical and quantum models. The former yield isolated solitons, their lattices and super-arrays. This theory is supported by mathematics of finite-band potentials and associated space-time nonlinear partial differential equations.
The experimental motivation for reviving these theories will be reviewed at the lectures given at the IBS-CALDES in PosTech on May 24&25.
