Integrability and dark states of the XX spin-1 central spin model in a transverse field
Eric De Nadai, Nathan Maestracci, Alexandre Faribault
It was recently shown that, for central spin-1/2 and central spin-1, the XX central spin model is integrable in the presence of a magnetic field oriented perpendicular to the XY pl…
Read-Green points and level crossings in XXZ central spin models and topological superconductors
Alexandre Faribault, Houda Koussir, Mohamed Houssein Mohamed
In this work, we study the full set of eigenstates of a topological superconductor coupled to a particle bath which can be described in terms of an integrable Hamiltonia…
Steady-states of out-of-equlibrium inhomogeneous Richardson-Gaudin quantum integrable models in quantum optics
Hugo Tschirhart, Thierry Platini, Alexandre Faribault
In this work we present numerical results for physical quantities in the steady-state obtained after a variety of product-states initial conditions are evolved unitarily, driven by…
Spin decoherence due to a randomly fluctuating spin bath
Alexandre Faribault, Dirk Schuricht
We study the decoherence of a spin in a quantum dot due to its hyperfine coupling to a randomly fluctuating bath of nuclear spins. The system is modelled by the central spin model…
Integrability-based analysis of the hyperfine-interaction -nduced decoherence in quantum dots
Alexandre Faribault, Dirk Schuricht
Using the Algebraic Bethe Ansatz in conjunction with a simple Monte Carlo sampling technique, we study the problem of the decoherence of a central spin coupled to a nuclear spin ba…
Non-equilibrum dynamics in the strongly excited inhomogeneous Dicke model
Christoph Sträter, Oleksandr Tsyplyatyev, Alexandre Faribault
Using the exact eigenstates of the inhomogeneous Dicke model obtained by numerically solving the Bethe equations, we study the decay of bosonic excitations due to the coupling of t…
