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…
Experimental parameters' Uncertainty limits for z-scan and f-scan techniques
Esteban Marulanda, Edgar Rueda
In this paper, we present an analytical study of the relationship between the statistical distribution of a physical parameter and the uncertainties in the physical quantities used…
Correspondence Between the Energy Equipartition Theorem in Classical Mechanics and its Phase-Space Formulation in Quantum Mechanics
Esteban Marulanda, Alejandro Restrepo, Johans Restrepo
In classical physics there is a well-known theorem in which it is established that the energy per degree of freedom is the same. However, in quantum mechanics due to the non-commut…
