Simulating Lindbladian evolution with non-abelian symmetries: Ballistic front propagation in the Hubbard model with a localized loss
Cătălin Paşcu Moca, Miklós Antal Werner, Örs Legeza +3
We develop a non-Abelian time evolving block decimation (NA-TEBD) approach to study of open systems governed by Lindbladian time evolution, while exploiting an arbitrary number of…
Correlations at PT-symmetric quantum critical point
Balázs Dóra, Doru Sticlet, Catalin Pascu Moca
We consider a PT-symmetric Fermi gas with an exceptional point, representing the critical point between PT-symmetric and symmetry broken phases. The low energy spectrum remains lin…
Uniform convergence for sequences of best L^{p} approximation
Donatella Bongiorno, Lucian Coroianu
Let be a continuous monotone real function defined on a compact interval of the real line. Given a sequence of partitions of , , $\left\Vert {Δ}_{n}\righ…
Dissipative dynamics in the free massive boson limit of the sine-Gordon model
Á. Bácsi, C. P. Moca, G. Zaránd +1
We study the dissipative dynamics of one-dimensional fermions, described in terms of the sine-Gordon model in its free massive boson or semi-classical limit, while keeping track of…
Non-Hermitian Lindhard function and Friedel oscillations
Balázs Dóra, Doru Sticlet, Cătălin Paşcu Moca
The Lindhard function represents the basic building block of many-body physics and accounts for charge response, plasmons, screening, Friedel oscillation, RKKY interaction etc. Her…
Kubo formula for non-Hermitian systems and tachyon optical conductivity
Doru Sticlet, Balázs Dóra, Cătălin Paşcu Moca
Linear response theory plays a prominent role in various fields of physics and provides us with extensive information about the thermodynamics and dynamics of quantum and classical…
