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…
Algebraic Approach to Entanglement and Entropy
A. P. Balachandran, T. R. Govindarajan, Amilcar R. de Queiroz +1
We present a general approach to quantum entanglement and entropy that is based on algebras of observables and states thereon. In contrast to more standard treatments, Hilbert spac…
A Dirac type xp-Model and the Riemann Zeros
Kumar S. Gupta, E. Harikumar, Amilcar R. de Queiroz
We propose a Dirac type modification of the xp-model to a $x \slashed{p}$ model on a semi-infinite cylinder. This model is inspired by recent work by Sierra et al on the xp-model o…
