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…
Reduced Density Matrices / Static Correlation Functions of Richardson-Gaudin States Without Rapidities
Alexandre Faribault, Claude Dimo, Jean-David Moisset +1
Seniority-zero geminal wavefunctions are known to capture bond-breaking correlation. Among this class of wavefunctions, Richardson-Gaudin states stand out as they are eigenvectors…
Gradient corrections to the local density approximation in the one-dimensional Bose gas
François Riggio, Yannis Brun, Dragi Karevski +2
The local density approximation (LDA) is the central technical tool in the modeling of quantum gases in trapping potentials. It consists in treating the gas as an assembly of indep…
Near-exact treatment of seniority-zero ground and excited states with a Richardson-Gaudin mean-field
Charles-Émile Fecteau, Samuel Cloutier, Jean-David Moisset +4
Eigenvectors of the reduced Bardeen-Cooper-Schrieffer Hamiltonian, Richardson-Gaudin (RG) states, are used as a variational wavefunction Ansatz for strongly-correlated electronic s…
Strong-coupling emergence of dark states in XX central spin models
Claude Dimo, Alexandre Faribault
It was recently shown that the XX central spin model is integrable in the presence of a magnetic field perpendicular to the plane in which the coupling exists. A large number of it…
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…
