Nonlinear Fluctuating Hydrodynamics from Interacting Noisy Quantum Matter
Alexios Christopoulos, João Costa, Stefano Scopa +4
A universal characterization of non-equilibrium steady states in interacting quantum many-body systems remains one of the central challenges of statistical physics. Here, we addres…
Symmetry as a route to generalized bosonic Kitaev chains
Gideon Lee, Tony Jin, Aashish A. Clerk
The bosonic Kitaev chain (BKC) model is a deceptively simple looking quadratic pairing Hamiltonian. Despite being purely Hermitian, it exhibits a number of striking non-Hermitian t…
Quantum-to-Classical Computability Transition via Negative Markov Chains
Hugo Lóio, Jacopo De Nardis, Tony Jin
We develop a recently introduced representation of quantum dynamics based on sampling negative Markov chain processes. By introducing particles and antiparticles, this formalism ma…
Universal classical and quantum fluctuations in the large deviations of current of noisy quantum systems: Quantum symmetric simple exclusion and inclusion processes
Mathias Albert, Denis Bernard, Tony Jin +2
We study the fluctuation statistics of integrated currents in noisy quantum diffusive systems, focusing on the Quantum Symmetric Simple Exclusion and Inclusion Processes (QSSEP/QSS…
Large deviations of density fluctuations in the boundary driven Quantum Symmetric Simple Inclusion Process
Denis Bernard, Tony Jin, Stefano Scopa +1
We consider the boundary driven Quantum Symmetric Simple Inclusion Process (QSSIP) which describes a one-dimensional system of bosonic particles with stochastic nearest-neighbor ho…
Measurement-induced phase transition in a single-body tight-binding model
Tony Jin, David G. Martin
We study the statistical properties of a single free quantum particle evolving coherently on a discrete lattice in spatial dimensions where every lattice site is addition…
Entanglement phase transition due to reciprocity breaking without measurement or post-selection
Gideon Lee, Tony Jin, Yu-Xin Wang +2
Despite its fully unitary dynamics, the bosonic Kitaev chain (BKC) displays key hallmarks of non-Hermitian physics including non-reciprocal transport and the non-Hermitian skin eff…

João Ferreira, Tony Jin, Jochen Mannhart +2
We study non-interacting fermionic systems undergoing continuous monitoring and driven by biased reservoirs. Averaging over the measurement outcomes, we derive exact formulas for t…
Bosonization of the interacting Su-Schrieffer-Heeger model
Tony Jin, Paola Ruggiero, Thierry Giamarchi
We derive the bosonization of the interacting fermionic Su-Schrieffer-Heeger (SSH) with open boundaries. We use the classical Euler-Lagrange equations of motions of the bosonized t…

We devise a semi-classical model to describe the transport properties of low-dimensional fermionic lattices under the influence of external quantum stochastic noise. These systems…
KPZ physics and phase transition in a classical single random walker under continuous measurement
Tony Jin, David G. Martin
We introduce and study a new model consisting of a single classical random walker undergoing continuous monitoring at rate on a discrete lattice. Although such a continuous mea…
Exact description of quantum stochastic models as quantum resistors
Tony Jin, João S. Ferreira, Michele Filippone +1
We study the transport properties of generic out-of-equilibrium quantum systems connected to fermionic reservoirs. We develop a new method, based on an expansion of the current in…
Interplay between transport and quantum coherences in free fermionic systems

We study the quench dynamics in free fermionic systems in the prototypical bipartitioning protocol obtained by joining two semi-infinite subsystems prepared in different states, ai…

We present a generic, compact formula for the current flowing in interacting and non-interacting systems which are driven out-of-equilibrium by biased reservoirs described by Lindb…

For a quantum system in a macroscopically large volume , prepared in a pure state and subject to maximally noisy or ergodic unitary dynamics, the reduced density matrix of any s…

M. Bauer, D. Bernard, T. Jin
We revisit aspects of monitoring observables with continuous spectrum in a quantum system subject to dissipative (Lindbladian) or conservative (Hamiltonian) evolutions. After recal…
Transport in quantum chains under strong monitoring
D. Bernard, T. Jin, O. Shpielberg
We study the transport properties of quantum 1D systems under strong monitoring. The quantum Zeno effect inhibits transport and induces localization. Beyond the Zeno freezing and o…
