The exchange coupling of a Wigner dimer
Daniele Lagasco, Zoran Ristivojevic
We study the exchange coupling in small Wigner crystals confined to one-dimensional space. In particular we concentrate on the simplest nontrivial case of two electrons in a box po…
Bethe-ansatz study of the Bose-Fermi mixture
Soham Chandak, Aleksandra Petković, Zoran Ristivojevic
We consider a one-dimensional mixture of bosons and spinless fermions with contact interactions. In this system, the elementary excitations at low energies are described by four li…
Exactly solvable models for universal operator growth
Oleksandr Gamayun, Murtaza Ali Mir, Oleg Lychkovskiy +1
Quantum observables of generic many-body systems exhibit a universal pattern of growth in the Krylov space of operators. This pattern becomes particularly manifest in the Lanczos b…
