The state-of-the-art on the thermodynamic optimization of absorption thermodynamic cycles
is presented in this paper. The review covers the endoreversible and irreversible three-heat …

We consider a paradigmatic quantum harmonic Otto engine operating in finite time. We
investigate its performance when shortcut-to-adiabaticity techniques are used to speed up …

We investigate the performance of a quantum thermal machine operating in finite time based
on shortcut-to-adiabaticity techniques. We compute efficiency and power for a paradigmatic …

The control and manipulation of quantum systems without excitation are challenging, due to
the complexities in fully modeling such systems accurately and the difficulties in controlling …

We present experimental evidence for scale invariant behaviour of the excitation spectrum in
phase-fluctuating quasi-1d Bose gases after a rapid change of the external trapping …

We introduce an approach for quantum computing in continuous time based on the Lewis–
Riesenfeld dynamic invariants. This approach allows, under certain conditions, for the …

A model of an irreversible quantum refrigerator with working medium consisting of many
noninteracting spin-1/2 systems is established in this paper. The quantum refrigeration cycle …

Atomic sensors are among the best devices for precision measurements of time, electric and
magnetic fields, and inertial forces. However, all atomic sensors that utilise uncorrelated …

In the scope of this thesis, an experiment was prepared to reliably produce Bose-Einstein
condensates in an atom chip trap. In this setup, the dynamics and relaxation processes …

Atom trapping on chip opens new perspectives for time and frequency metrology and
integrated atom interferometry. The TACC experiment (Trapped Atomic Clock on a Chip) …
