A superintegrable quantum field theory
Marine De Clerck, Oleg Evnin
Gérard and Grellier proposed, under the name of the cubic SzegÅ equation, a remarkable classical field theory on a circle with a quartic Hamiltonian. The Lax integrability struct…
Unified theory of local integrals of motion
Ben Craps, Oleg Evnin, Dmitry Kovrizhin +1
Many-body localization (MBL) is understood theoretically through the existence of an extensive number of local integrals of motion (LIOMs). These conserved quantities are related t…
Analytic and numerical toolkit for the Anderson model in one dimension
Oleg Evnin
The Anderson model in one dimension is a quantum particle on a discrete chain of sites with nearest-neighbor hopping and random on-site potentials. It is a progenitor of many furth…
Multiseed Krylov complexity
Ben Craps, Oleg Evnin, Gabriele Pascuzzi
Krylov complexity is an attractive measure for the rate at which quantum operators spread in the space of all possible operators under dynamical evolution. One expects that its lat…
Phase-space localization at the lowest Landau level
Ben Craps, Marine De Clerck, Oleg Evnin +1
We consider bosons with weak contact interactions in a harmonic trap and focus on states at the lowest Landau level. Motivated by the known nontrivial phase-space topography of the…
