On the Möbius transformation in the entanglement entropy of fermionic chains
F. Ares, J. G. Esteve, F. Falceto +1
There is an intimate relation between entanglement entropy and Riemann surfaces. This fact is explicitly noticed for the case of quadratic fermionic Hamiltonians with finite range…

Generalized Central Limit Theorem and Renormalization Group
I. Calvo, J. C. Cuchí, J. G. Esteve +1
We introduce a simple instance of the renormalization group transformation in the Banach space of probability densities. By changing the scaling of the renormalized variables we ob…
