Decoherence and relaxation of topological states in extended quantum Ising models
Hannes Weisbrich, Wolfgang Belzig, Gianluca Rastelli
We study the decoherence and the relaxation dynamics of topological states in an extended class of quantum Ising chains which can present a manyfold ground state subspace. The lead…
Microwave Spectroscopy Reveals the Quantum Geometric Tensor of Topological Josephson Matter
Raffael L. Klees, Gianluca Rastelli, Juan Carlos Cuevas +1
Quantization effects due to topological invariants such as Chern numbers have become very relevant in many systems, yet key quantities such as the quantum geometric tensor providin…
Quantum Coherent Multielectron Processes in an Atomic Scale Contact
Peter-Jan Peters, Fei Xu, Kristen Kaasbjerg +3
The light emission from a scanning tunneling microscope operated on a Ag(111) surface at 6 K is analyzed from low conductances to values approaching the conductance quantum. Optica…
Dynamical multistability in a quantum-dot laser
Mattia Mantovani, Andrew D. Armour, Wolfgang Belzig +1
We study the dynamical multistability of a solid-state single-atom laser implemented in a quantum-dot spin valve. The system is formed by a resonator that interacts with a two-leve…
Decoherence in the quantum Ising model with transverse dissipative interaction in the strong coupling regime
Hannes Weisbrich, C. Saussol, Wolfgang Belzig +1
We study the decoherence dynamics of a quantum Ising lattice of finite size with a transverse dissipative interaction, namely the coupling with the bath is assumed perpendicular to…
