Signature structure of quadratic response under Zeno-Schur coarse graining in open quantum systems
Ansgar Pernice
Quadratic response tensors arise naturally in quantum kinetic descriptions, such as the quantum linear Boltzmann equation (QLBE), where they encode the coupled structure of drift a…
Zeno-Constrained Formation of Relativistic Mass Shells
Ansgar Pernice
We study an extension of the quantum linear Boltzmann equation describing irreversible momentum-space dynamics of an open quantum system under strong continuous monitoring. The mon…
System-environment correlations and Non-Markovian dynamics
Ansgar Pernice, Julius Helm, Walter T. Strunz
We determine the total state dynamics of a dephasing open quantum system using the standard environment of harmonic oscillators. Of particular interest are random unitary approache…
Decoherence and the Nature of System-Environment Correlations
A. Pernice, W. T. Strunz
We investigate system-environment correlations based on the exact dynamics of a qubit and its environment in the framework of pure decoherence (phase damping). We focus on the rela…
