A mobile impurity immersed in a noninteracting Fermi sea is dressed by the gapless particle-
hole excitations of the fermionic medium. This conventional Fermi-polaron setting is well …

Lattice polarons, quasiparticles arising from the interaction between an impurity and its
surrounding bosonic environment confined to a lattice system, have emerged as a platform …

Immersing a mobile impurity in a quantum many-body environment can reveal fundamental
properties of the background medium, hence providing a powerful probe of quantum matter …

We study two mobile bosonic impurities immersed in a one-dimensional optical lattice and
interacting with a bosonic bath. We employ the exact diagonalization method for small …

Detecting vortices in neutral superfluids represents an outstanding experimental challenge.
Using stochastic classical-field methods, we theoretically show that a quantum impurity …

Impurities immersed in hard-core Bose gases offer exciting opportunities to explore polaron
and bipolaron physics. We investigate the ground state properties of a single and a pair of …

In this work we study a system of interacting fermions on a triangular lattice in the presence
of an external magnetic field. We neglect spin and fix a density of one third, with one unit of …
