Galilean boost invariance does not survive the trace: symmetry breaking in open quantum systems
Leonardo F. Calderón, Esteban Marulanda, Santiago Morales +1
Tracing out a Galilean-invariant Caldeira-Leggett environment breaks Galilean boost covariance of the reduced dynamics, while spatial translations and rotations survive intact. An…

Generalized Finite Differences Method Applied to Finite Photonic Crystal
Santiago Bustamante, Esteban Marulanda, Jorge Mahecha +1
We propose a Generalized Finite-Differences in the Frequency Domain method for the computation of photonic band structures of finite photonic crystals. Our approach is to discretiz…

Influence of Initial Entangled States on the Temperature-Dependent CHSH Inequality
Esteban Marulanda, Andrés Gómez
We demonstrate that the temperature affects the validity of the CHSH inequality in an open bipartite two-qubit system. Specifically, for initial entangled states within the decoher…
