Title: Physical consequences of Lindbladian invariance transformations
Authors: Yohan Vianna de Almeida, Fernando Nicacio, Marcelo F. Santos,
Abstract summary: We show that symmetry transformations can be exploited, on their own, to optimize practical physical tasks. In particular, we show how they can be used to change the measurable values of physical quantities regarding the exchange of energy and/or information with the environment.

Abstract: On its own, the invariance properties of Markovian master equations have mostly played a mathematical or computational role in the evaluation of quantum open system dynamics. Because all forms of the equation lead to the same time evolution for the state of the system, the fixation of a particular form has only gained physical meaning when correlated with additional information such as in the evolution of quantum trajectories or the study of decoherence-free subspaces. Here, we show that these symmetry transformations can be exploited, on their own, to optimize practical physical tasks. In particular, we present a general formulation showing how they can be used to change the measurable values of physical quantities regarding the exchange of energy and/or information with the environment. We also analyze examples of optimization in quantum thermodynamics and, finally, discuss practical implementations in terms of quantum trajectories.

External gauge field coupled quantum dynamics: gauge choices, Heisenberg algebra representations and gauge invariance in general, and the Landau problem in particular [0.0]
An additive total derivative or divergence term induces nontrivial consequences for the system's canonical phase space formulation. Under such transformations the system's degrees of freedom, abstract quantum states and quantum dynamics are certainly strictly invariant. The role of the global space-time symmetries of the Landau problem and their gauge invariant Noether charges is then also emphasized.

Dynamics of entropy and information of time-dependent quantum systems: exact results [0.0]
Dynamical aspects of information-theoretic and entropic measures of quantum systems are studied. We show that for the time-dependent harmonic oscillator, as well as for the charged particle in certain time-varying electromagnetic fields, the increase of the entropy and dynamics of the Fisher information can be directly described and related. We detail the behavior of quantum quenches for the case of mutually non-interacting non-relativistic fermions in a harmonic trap.
