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…

Quantum-classical transition and quantum activation of ratchet currents in the parameter space

M. W. Beims, M. Schlesinger, C. Manchein +3

The quantum ratchet current is studied in the parameter space of the dissipative kicked rotor model coupled to a zero temperature quantum environment. We show that vacuum fluctuati…

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…
