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…

Entanglement in fermionic chains with finite range coupling and broken symmetries
F. Ares, J. G. Esteve, F. Falceto +1
We obtain a formula for the determinant of a block Toeplitz matrix associated with a quadratic fermionic chain with complex coupling. Such couplings break reflection symmetry and/o…
