Enhancement of Charge Density Wave Correlations in a Holstein Model with an Anharmonic Phonon Potential
C. Kvande, C. Feng, F. Hébert +2
The Holstein Hamiltonian describes itinerant electrons whose site density couples to local phonon degrees of freedom. In the single site limit, at half-filling, the electron-phonon…
Gravitational-wave echoes from numerical-relativity waveforms via space-time construction near merging compact objects
Sizheng Ma, Qingwen Wang, Nils Deppe +7
We propose a new approach toward reconstructing the late-time near-horizon geometry of merging binary black holes, and toward computing gravitational-wave echoes from exotic compac…
Simulating magnetized neutron stars with discontinuous Galerkin methods
Nils Deppe, François Hébert, Lawrence E. Kidder +33
Discontinuous Galerkin methods are popular because they can achieve high order where the solution is smooth, because they can capture shocks while needing only nearest-neighbor com…
Quantum Monte Carlo study of an anharmonic Holstein model
G. Paleari, F. Hébert, B. Cohen-Stead +3
We study the effects of anharmonicity on the physics of the Holstein model, which describes the coupling of itinerant fermions and localized quantum phonons, by introducing a quart…
Scaling properties of the Tan's contact: embedding pairs and correlation effect in the Tonks limit
F. T. Sant'Ana, F. Hébert, V. Rousseau +2
We study the Tan's contact of a one dimensional quantum gas of N repulsive identical bosons confined in a harmonic trap at finite temperature. This canonical ensemble framework cor…
Two-photon Rabi-Hubbard and Jaynes-Cummings-Hubbard models: photon pair superradiance, Mott insulator and normal phases
Shifeng Cui, F. Hébert, B. Grémaud +3
We study the ground state phase diagrams of two-photon Dicke, the one-dimensional Jaynes-Cummings-Hubbard (JCH), and Rabi-Hubbard (RH) models using mean field, perturbation, quantu…
