Edge States at Phase Boundaries and Their Stability
M. Asorey, A. P. Balachandran, J. M. Perez-Pardo
We analyse the effects of Robin boundary conditions on quantum field theories of spin 0, 1 and 1/2. In particular, we show that these conditions always lead to the appearance of ed…

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…
