Killing Horizons and Spinors
Bruno Carneiro da Cunha, Amilcar de Queiroz
We study the near horizon geometry of generic Killing horizons constructing suitable coordinates and taking the appropriate scaling limit. We are able to show that the geometry wil…
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…
Quantum Entropic Ambiguities: Ethylene
A. P. Balachandran, Amilcar R. de Queiroz, S. Vaidya
In a quantum system, there may be many density matrices associated with a state on an algebra of observables. For each density matrix, one can compute its entropy. These are in gen…
