Quantum fluctuation theorems and generalized measurements during the force protocol
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +2
Generalized measurements of an observable performed on a quantum system during a force protocol are investigated and conditions that guarantee the validity of the Jarzynski equalit…
Non-normalizable densities in strong anomalous diffusion: beyond the central limit theorem
A. Rebenshtok, S. Denisov, P. Hanggi +1
Strong anomalous diffusion, where with a nonlinear spectrum $ν(q) \neq \mbox{const}$, is wide spread and has been found in various nonlin…
Entanglement creation in a quantum dot-nanocavity system
Ralf Blattmann, Hubert Krenner, Sigmund Kohler +1
We explore the possibility to entangle an excitonic two-level system in a semiconductor quantum dot (QD) with a cavity defined on a photonic crystal by sweeping the cavity frequenc…
Tunable transport with broken space-time symmetries
Sergey Denisov, Sergej Flach, Peter Hanggi
Transport properties of particles and waves in spatially periodic structures that are driven by external time-dependent forces manifestly depend on the space-time symmetries of the…
Characterization of Qubit Dephasing by Landau-Zener Interferometry
F. Forster, G. Petersen, S. Manus +5
Controlling coherent interaction at avoided crossings is at the heart of quantum information processing. The regime between sudden switches and adiabatic transitions is characteriz…
Boosting work characteristics and overall heat engine performance via shortcuts to adiabaticity: quantum and classical systems
Jiawen Deng, Qing-hai Wang, Zhihao Liu +2
Under a general framework, shortcuts to adiabatic processes are shown to be possible in classical systems. We then study the distribution function of the work done on a small syste…
