Exact spectral function of a Tonks-Girardeau gas in a lattice
J. Settino, N. Lo Gullo, F. Plastina +1
The single-particle spectral function of a strongly correlated system is an essential ingredient to describe its dynamics and transport properties. We develop a general method to c…
Signatures of the single particle mobility edge in the ground state properties of Tonks-Girardeau and non-interacting Fermi gases in a bichromatic potential
J. Settino, N. Lo Gullo, A. Sindona +2
We explore the ground state properties of cold atomic gases, loaded into a bichromatic lattice, focusing on the cases of non-interacting fermions and hard-core (Tonks-Girardeau) bo…
Local Quench, Majorana Zero Modes, and Disturbance Propagation in the Ising chain
G. Francica, T. J. G. Apollaro, N. Lo Gullo +1
We study the generation and propagation of local perturbations in a quantum many-body spin system. In particular, we study the Ising model in transverse field in the presence of a…
