Number of closed-channel molecules in the BEC-BCS crossover
Felix Werner, Leticia Tarruell, Yvan Castin
Using a two-channel model, we show that the number of closed channel molecules in a two-component Fermi gas close to a Feshbach resonance is directly related to the derivative of t…

Entanglement Skyrmions in multicomponent quantum Hall systems
B. Doucot, M. O. Goerbig, P. Lederer +1
We discuss charged topological spin textures in quantum Hall ferromagnets in which the electrons carry a pseudospin as well as the usual spin degree of freedom, as is the case in b…

T-duality in Ramond-Ramond backgrounds
Raphael Benichou, Giuseppe Policastro, Jan Troost
Using the pure spinor formalism on the world-sheet, we derive the T-duality rules for all target space couplings in an efficient manner. The world-sheet path integral derivation is…
