Semiclassical analysis of spin dynamics in the non-Hermitian Hubbard model
Doru Sticlet, Cătălin Paşcu Moca, Balázs Dóra
We investigate a specific limit of the one-dimensional non-Hermitian Hubbard Hamiltonian with complex interactions. In this framework, fermions with different spin quantum numbers…
Slow approach to adiabaticity in many-body non-Hermitian systems: the Hatano-Nelson Model
Léonce Dupays, Adolfo del Campo, Balázs Dóra
We explore the near adiabatic dynamics in a non-Hermitian quantum many-body system by investigating a finite-time ramp of the imaginary vector potential in the interacting Hatano-N…
Exact Dynamics and Shortcuts to Adiabaticity in the Tomonaga-Luttinger Liquid
Léonce Dupays, Balázs Dóra, Adolfo del Campo
Controlling many-body quantum systems is a highly challenging task required to advance quantum technologies. Here, we report progress in controlling gapless many-body quantum syste…
A simple electronic ladder model harboring parafermions
Botond Osváth, Gergely Barcza, Örs Legeza +2
Parafermions are anyons with the potential for realizing non-local qubits that are resilient to local perturbations. Compared to Majorana zero modes, braiding of parafermions imple…
Work statistics and generalized Loschmidt echo for the Hatano-Nelson model
Balázs Dóra, Cătălin Paşcu Moca
We focus on the biorthogonal work statistics of the interacting many-body Hatano-Nelson model after switching on the imaginary vector potential. We introduce a generalized Loschmid…
Comparative Ta-NQR Study of Weyl Monopnictides TaAs and TaP: Relevance of Weyl Fermion Excitations
Tetsuro Kubo, Hiroshi Yasuoka, Balázs Dóra +6
Based on our first detailed Ta nuclear quadrupole resonance (NQR) studies from 2017 on the Weyl semimetal TaP, we now extended our NQR studies to another Ta-based monopnict…
Quantum quench dynamics in the Luttinger liquid phase of the Hatano-Nelson model
Balázs Dóra, Miklós Antal Werner, Cătălin Paşcu Moca
We investigate the quantum quench dynamics of the interacting Hatano-Nelson model with open boundary conditions using both abelian bosonization and numerical methods. Specifically,…
Correlations at higher-order exceptional points in non-Hermitian models
Doru Sticlet, Cătălin Paşcu Moca, Balázs Dóra
We investigate the decay of spatial correlations of -symmetric non-Hermitian one-dimensional models that host higher-order exceptional points. Beyond a certain correl…
Full counting statistics in the many-body Hatano-Nelson model
B. Dóra, C. P. Moca
We study non-hermitian many-body physics in the interacting Hatano-Nelson model with open boundary condition. The violation of reciprocity, resulting from an imaginary vector poten…
An intuitive approach to the unified theory of spin-relaxation
L. Szolnoki, B. Dora, A. Kiss +2
Spin-relaxation is conventionally discussed using two different approaches for materials with and without inversion symmetry. The former is known as the Elliott-Yafet (EY) theory a…
Stabilizing the false vacuum: Mott skyrmions
Márton Kanász-Nagy, Balázs Dóra, Eugene A. Demler +1
Topological excitations keep fascinating physicists since many decades. While individual vortices and solitons emerge and have been observed in many areas of physics, their most in…
Diverging dc conductivity due to a flat band in disordered pseudospin-1 Dirac-Weyl fermions
Máté Vigh, László Oroszlány, Szabolcs Vajna +4
Several lattices, such as the dice or the Lieb lattice, possess Dirac cones and a flat band crossing the Dirac point, whose effective model is the pseudospin-1 Dirac-Weyl equation.…
Enhanced NMR relaxation of Tomonaga-Luttinger liquids and the magnitude of the carbon hyperfine coupling in single-wall carbon nanotubes
A. Kiss, A. Palyi, Y. Ihara +8
Recent transport measurements [Churchill \textit{et al.} Nat. Phys. \textbf{5}, 321 (2009)] found a surprisingly large, 2-3 orders of magnitude larger than usual C hyperfine…
