Quantum localization in open chaotic systems [PDF]
Physical Review E, 2008 We study a quasi-Floquet state of a $δ$-kicked rotor with absorbing boundaries focusing on the nature of the dynamical localization in open quantum systems. The localization lengths $ξ$ of lossy quasi-Floquet states located near the absorbing boundaries decrease as they approach the boundary while the corresponding decay rates $Γ$ are dramatically ...

Scarring in open quantum systems
Physical Review E, 2008 We study scarring phenomena in open quantum systems. We show numerical evidence that individual resonance eigenstates of an open quantum system present localization around unstable short periodic orbits in a similar way as their closed counterparts. The structure of eigenfunctions around these classical objects is not destroyed by the opening.

Exploiting coherence for quantum thermodynamic advantage
New Journal of Physics, 2022 The introduction of the quantum analogue of a Carnot engine based on a bath comprising of particles with a small amount of coherence initiated an active line of research on the harnessing of different quantum resources for the enhancement of thermal ...

Many-body open quantum systems
SciPost Physics Lecture NotesThese lecture notes discuss the recent theoretical advances in the understanding of open quantum many-body physics in platforms where both dissipative and coherent processes can be tuned and controlled to a high degree.

Embedding the Yang-Lee quantum criticality in open quantum systems
Physical Review Research, 2022 The Yang-Lee edge singularity is a quintessential nonunitary critical phenomenon characterized by anomalous scaling. However, an imaginary magnetic field involved in this phenomenon makes its physical implementation nontrivial.

High fidelity quantum gates of trapped ions in the presence of motional heating
New Journal of Physics, 2016 We describe entangling quantum gates for trapped ions mediated by a dissipative bus mode and show that suitably designed, polychromatic control pulses decrease ion-phonon entanglement substantially while maintaining the mediated interaction.
