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…

Emergence of anomalous dynamics from the underlying singular continuous spectrum in interacting many-body systems
J. Settino, N. W. Talarico, F. Cosco +3
We investigate the dynamical properties of an interacting many-body system with a non-trivial energy potential landscape that may induce a singular continuous single-particle energ…
