Two-component Bose gases with one-body and two-body couplings
Samuel Lellouch, Tung-Lam Dao, Thomas Koffel +1
We study the competition between one-body and two-body couplings in weakly-interacting two-component Bose gases, in particular as regards field correlations. We derive the meanfiel…

Entanglement entropy for the long range Ising chain
Thomas Koffel, M. Lewenstein, Luca Tagliacozzo
We consider the Ising model in a transverse field with long-range antiferromagnetic interactions that decay as a power law with their distance. We study both the phase diagram and…
