Lattice Bose polarons at strong coupling and quantum criticality
Ragheed Alhyder, Victor E. Colussi, Matija Čufar +3
We develop a new theoretical framework for exploring a mobile impurity interacting strongly with a highly correlated bath of bosons in the quantum critical regime of a Mott insulat…
Effective theory for strongly attractive one-dimensional fermions
Timothy G. Backert, Fabian Brauneis, Matija Čufar +3
We study a one-dimensional system of two-component fermions in the limit of strong attractive particle-particle interactions. First, we analyze scattering in the corresponding few-…
Polaron-Depleton Transition in the Yrast Excitations of a One-Dimensional Bose Gas with a Mobile Impurity
Mingrui Yang, Matija Čufar, Elke Pahl +1
We present exact numerical data for the lowest-energy momentum eigenstates (yrast states) of a repulsive spin impurity in a one-dimensional Bose gas using full configuration intera…
