Universal properties and dynamical bosonization of strongly interacting one-dimensional anyons

Ovidiu I. Patu

We study a one-dimensional system of strongly interacting anyons with short-range interactions under external confinement. This system, referred to as -wave anyons, interpolates…

Quantum Coherence in a Maximally Hot Hubbard Chain

Cătălin Paşcu Moca, Ovidiu I. Patu, Balázs Dóra +1

We present a detailed study of the real-time dynamics and spectral properties of the one-dimensional fermionic Hubbard model at infinite temperature. Using tensor network simulatio…

Expansion of one-dimensional spinor gases from power-law traps

Ovidiu I. Patu, Gianni Aupetit-Diallo

Free expansion following the removal of axial confinement represents a fundamental nonequilibrium scenario in the study of many-body ultracold gases. Using the stationary phase app…

Exact spectral function and nonequilibrium dynamics of the strongly interacting Hubbard model

Ovidiu I. Patu, Andreas Klumper, Angela Foerster

Analytical results on the correlation functions of strongly correlated many-body systems are rare in the literature and their importance cannot be overstated. We present determinan…

Numerical methods and analytic results for one-dimensional strongly interacting spinor gases

Ovidiu I. Patu

One of quantum physics' fundamental, but largely unsolved, problems is the computation of the correlation functions in many-body systems. In this paper we address this problem in t…
