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…

Competition between Phase Separation and Spin Density Wave or Charge Density Wave Order: Role of Long-Range Interactions
Bo Xiao, F. Hébert, G. Batrouni +1
Recent studies of pairing and charge order in materials such as FeSe, SrTiO, and 2H-NbSe have suggested that momentum dependence of the electron-phonon coupling plays an im…
