Supercurrent-enabled Andreev reflection in a chiral quantum Hall edge state
Andreas B. Michelsen, Patrik Recher, Bernd Braunecker +1
A chiral quantum Hall (QH) edge state placed in proximity to an s-wave superconductor experiences induced superconducting correlations. Recent experiments have observed the effect…
Subgap states at ferromagnetic and spiral-ordered magnetic chains in two-dimensional superconductors. II. Topological classification
C. J. F. Carroll, B. Braunecker
We investigate the topological classification of the subgap bands induced in a two-dimensional superconductor by a densely packed chain of magnetic moments with ferromagnetic or sp…
Spatiotemporal Spread of Fermi-edge Singularity as Time Delayed Interaction and Impact on Time-dependent RKKY Type Coupling
Conor Jackson, Bernd Braunecker
Fermi-edge singularity and Anderson's orthogonality catastrophe are paradigmatic examples of non-equilibrium many-body physics in conductors, appearing after a quench is created by…
Quantum measurement induces a many-body transition
Michael S. Ferguson, Leon C. Camenzind, Clemens Müller +5
The current revolution in quantum technologies relies on the ability to isolate, coherently control, and measure the state of quantum systems. The act of measurement in quantum mec…
Decoupled heat and charge rectification as a many-body effect in quantum wires
Conor Stevenson, Bernd Braunecker
We show that for a quantum wire with a local asymmetric scattering potential the principal channels for charge and heat rectification decouple and renormalise differently under ele…
Coherent backaction between spins and an electronic bath: Non-Markovian dynamics and low-temperature quantum thermodynamic electron cooling
Stephanie Matern, Daniel Loss, Jelena Klinovaja +1
We provide a versatile analytical framework for calculating the dynamics of a spin system in contact with a fermionic bath beyond the Markov approximation. The approach is based on…
