- Abstract summary: We study how translationally invariant couplings of many-particle systems and nonequilibrium baths can be used to rectify particle currents.
We show that unidirectional particle transport can occur when a Lindblad operator is reciprocal provided that the inversion symmetry and the time-reversal symmetry of the microscopic Hamiltonian are broken.

- Abstract: We study how translationally invariant couplings of many-particle systems and
nonequilibrium baths can be used to rectify particle currents, for which we
consider minimal setups to realize bath-induced currents in nonequilibrium
steady states of one-dimensional open fermionic systems. We first analyze
dissipative dynamics associated with a nonreciprocal Lindblad operator and
identify a class of Lindblad operators that are sufficient to acquire a
unidirectional current. We show that unidirectional particle transport can in
general occur when a Lindblad operator is reciprocal provided that the
inversion symmetry and the time-reversal symmetry of the microscopic
Hamiltonian are broken. We demonstrate this mechanism on the basis of both
analytical and numerical approaches including the Rashba spin-orbit coupling
and the Zeeman magnetic field.

Non-reciprocal propagation of energy and information is fundamental to a wide range of quantum technology applications.
We show that interplay between anti-symmetric (symmetric) coherent and symmetric (anti-symmetric) dissipative interactions results in non-reciprocal couplings.
We pave the way for realizing cooperative non-reciprocal transport in qubit ensembles without requiring time-modulated external drives or complex engineering.

We study a Lindbladian, describing a square-lattice spin-liquid with dissipative coupling to the environment, that admits an exact solution in terms of Majorana fermions coupled to $mathZ$ gauge fields.
This solution allows us to characterize the steady-state solutions as well as quasiparticle'' excitations within the Lindbladian spectrum.
This exactly solvable Lindbladian is expected to provide a starting point for a better understanding of the behavior of fractionalized systems under dissipative time evolution.

We consider a system of interacting spinless fermions on a two-leg triangular ladder with $pi/2$ magnetic flux per triangular plaquette.
Microscopically, the system exhibits a U(1) symmetry corresponding to the conservation of total fermionic charge, and a discrete $mathbbZ$ symmetry.
At the intersection of the three phases, the system features a critical point with an emergent SU(2) symmetry.

Signatures of localization have been observed in condensed matter and cold atomic systems.
We propose a model of one-dimensional chain of non-interacting, spinless fermions coupled to a local ensemble of baths.
We show that the steady state of the system undergoes a localization entanglement phase transition by tuning $p$ which remains stable in the presence of coherent hopping.
