Dark state semilocalization of quantum emitters in a cavity
Thomas Botzung, David Hagenmüller, Stefan Schütz +3
We study a disordered ensemble of quantum emitters collectively coupled to a lossless cavity mode. The latter is found to modify the localization properties of the "dark" eigenstat…

One-dimensional extended Hubbard model with soft-core potential
Thomas Botzung, Guido Pupillo, Pascal Simon +2
We investigate the phase diagram of a variant of the one-dimensional extended Hubbard model where particles interact via a finite-range soft-shoulder potential. Using Density…

Algebraic Localization from Power-Law Interactions in Disordered Quantum Wires
Thomas Botzung, Davide Vodola, Piero Naldesi +3
We analyze the effects of disorder on the correlation functions of one-dimensional quantum models of fermions and spins with long-range interactions that decay with distance …
