Accurate Truncations of Chain Mapping Models for Open Quantum Systems
Nanomaterials, 2021 The dynamics of open quantum systems are of great interest in many research fields, such as for the interaction of a quantum emitter with the electromagnetic modes of a nanophotonic structure.

Universal Fidelity Reduction of Quantum Operations from Weak Dissipation. [PDF]
Physical Review Letters, 2021 Quantum information processing is in real systems often limited by dissipation, stemming from remaining uncontrolled interaction with microscopic degrees of freedom.

Algebraic theory of quantum synchronization and limit cycles under dissipation [PDF]
SciPost Physics, 2021 Synchronization is a phenomenon where interacting particles lock their motion and display non-trivial dynamics. Despite intense efforts studying synchronization in systems without clear classical limits, no comprehensive theory has been found. We develop

Quantum Dissipative Rashba Spin Ratchets [PDF]
Physical Review Letters, 2008 We predict the possibility to generate a finite stationary spin current by applying an unbiased ac driving to a quasi-one-dimensional asymmetric periodic structure with Rashba spin-orbit interaction and strong dissipation. We show that under a finite coupling strength between the orbital degrees of freedom the electron dynamics at low temperatures ...

Exponential time-scaling of estimation precision by reaching a quantum critical point
Physical Review Research, 2022 Quantum metrology refers to the use of quantum resources in parameter-estimation protocols, aiming at enhancing its precision. The quantum Fisher information is a key quantity in this context, setting the ultimate achievable precision with respect to ...
