Active Quantum Matter from Monitored Pure-State Dynamics

Anonymous, Felix von Oppen, Reinhold Egger

Quantum many-body systems coupled to out-of-equilibrium reservoirs can behave as active matter and exhibit signs of flocking. However, the resulting steady states are highly mixed and carry only weak quantum signatures. We show that signatures of active matter also arise in ensembles …

Information transport and transport-induced entanglement in open fermion chains

Anonymous, Claudia Artiaco, Yuval Gefen, I. V. Gornyi et autres

Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin to transport equations for charge or heat, would be of great interest but face severe challenges because of the inherent nonlocality …

Exponential Speedup of Entanglement Generation by Quantum Mpemba Effects

Sara M. Benjadi, Reinhold Egger, Igor Gornyi, Andrea Nava

Entanglement is a key resource for quantum technologies. We show that protocols employing quantum Mpemba effects allow one to exponentially accelerate the generation of entanglement, or to slow down the decay thereof. Two entanglement Mpemba effects with different operational meaning are introduced, …

DC Conductance of X-shaped Majorana Interferometer reveals Non-Abelian Anyon Statistics

Domenico Giuliano, Andrea Nava, Reinhold Egger, Fabian Hassler

We propose a four-terminal, X-shaped chiral Majorana interferometer with a central floating superconducting island, enabling the direct detection of the non-Abelian statistics of Ising anyons via the linear-response DC conductance tensor in charge transport experiments. Here, Ising anyons are realizable as edge …

Parity readout in Majorana box qubits from the dispersive to the resonant regime

Sara M. Benjadi, Reinhold Egger

We study theoretical models for charge reflectometry and capacitive readout of the Majorana parity degree of freedom in Majorana box qubits, considering decoherence channels within the framework of the Lindblad master equation. Noting that a parity-dependent dynamical susceptibility χ z ( ω …

Optimal speed-up of multi-step Pontus–Mpemba protocols

Marco Peluso, Reinhold Egger, Andrea Kazemi Nava

Abstract The classical Mpemba effect is the counterintuitive phenomenon where hotter water freezes faster than colder water due to the breakdown of Newton’s law of cooling after a sudden temperature quench. The genuine nonequilibrium post-quench dynamics allows the system to evolve along …

Postquench relaxation dynamics of Gross-Neveu lattice fermions

Domenico Giuliano, Reinhold Egger, Bidyut Dey, Andrea Kazemi Nava

We study the quantum relaxation dynamics for a lattice version of the one-dimensional N -flavor Gross-Neveu model after a Hamiltonian parameter quench. Allowing for a system-reservoir coupling γ , we numerically describe the system dynamics through a time-dependent self-consistent Lindblad master equation. …
