Generalization of the Hartree-Fock-Bogoliubov theory: one and two quasiparticle excitations
Paolo Tommasini, E. J. V. de Passos, M. O. C. Pires +1
We present a generalization of the Hartree-Fock Bogoliubov (HFB) theory in which the coupling between one and two quasi-particles is taken into account.This is done by writing the…
Molecular Signatures in Hybrid Atomic/Molecular Bose-Einstein Condensates
Chi-Yong Lin, Paolo Tommasini, E. J. V. de Passos +3
As it was proposed and recently verified experimentally, the mechanism of Feshbach resonance in a condensate can create a second condensate component of molecules that coexists wit…
Inter-Condensate Tunneling in Bose-Einstein Condensates with Feshbach Resonances
Eddy Timmermans, Paolo Tommasini, Robin Cote +2
Recently, effects of Feshbach resonances in atom-atom interactions were observed by varying the external magnetic field of an atomic Bose-Einstein condensate (BEC). We point out th…
Feshbach Resonance and Hybrid Atomic/Molecular BEC-Systems
Paolo Tommasini, Eddy Timmermans, Mahir Hussein +1
The interactions responsible for Feshbach resonances in binary atom collisions produce a condensate of molecules in the atomic BEC-system. We discuss the `ground state' of the cond…
The Hydrogen Atom as an Entangled Electron-Proton System
Paolo Tommasini, Eddy Timmermans, A. F. R. de Toledo Piza
We illustrate the description of correlated subsystems by studying the simple two-body Hydrogen atom. We study the entanglement of the electron and proton coordinates in the exact…
Thomas-Fermi Description of Incoherent Light Scattering from an Atomic-Trap BEC
Eddy Timmermans, Paolo Tommasini
We present a Thomas-Fermi treatment of resonant incoherent scattering of low-intensity light by a dilute spatially confined Bose-Einstein condensate. The description gives simple a…
