Spontaneous symmetry restoration in a field theory at finite chemical potential in a toroidal topology
C. A. Linhares, A. P. C. Malbouisson, J. M. C. Malbouisson +1
We consider the massive vector -component theory defined on a Euclidean space with a toroidal topology. Using recently developed methods to perform a compactifica…
Two interacting fermions in a 1D harmonic trap: matching the Bethe ansatz and variational approaches
D. Rubeni, A. Foerster, I. Roditi
In this work, combining the Bethe ansatz approach with the variational principle, we calculate the ground state energy of the relative motion of a system of two fermions with spin…
Quantum Bose and Fermi gases with large negative scattering length in the 2-body S-matrix approximation
Andre LeClair, Edgar Marcelino, Andre Nicolai +1
We study both Bose and Fermi gases at finite temperature and density in an approximation that sums an infinite number of many body processes that are reducible to 2-body scattering…
Quantum phase transitions in Bose-Einstein condensates from a Bethe ansatz perspective
D. Rubeni, A. Foerster, E. Mattei +1
We investigate two solvable models for Bose-Einstein condensates and extract physical information by studying the structure of the solutions of their Bethe ansatz equations. A care…
