First order Quantum Hall to Wigner crystal phase transition on a triangular lattice: an iDMRG study
Gleb Fedorovich, Clemens Kuhlenkamp, Atac Imamoglu +1
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 o…

Polaron formation in insulators and the key role of hole scattering processes: Band insulators, charge density waves and Mott transition
Ivan Amelio, Giacomo Mazza, Nathan Goldman
A mobile impurity immersed in a non-interacting Fermi sea is dressed by the gapless particle-hole excitations of the fermionic medium. This conventional Fermi-polaron setting is we…
