Rimu.jl: Random integrators for many-body quantum systems
Matija Äufar, Matija Čufar, C. J. Bradly +3
Rimujl is a Julia package for solving many-body quantum problems. The core of the package is a matrix-free implementation of Hamiltonians and other operators and compact represe…

Effective theory for strongly attractive one-dimensional fermions
Timothy G. Backert, Fabian Brauneis, Matija Äufar +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-…

Lattice Bose polarons at strong coupling and quantum criticality
Ragheed Alhyder, Victor E. Colussi, Matija Äufar +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…
