Dissipative Synthesis of Mechanical Fock-Like States

open access: yesProceedings, 2019
The observation of genuine quantum features of nano-mechanical motion is a key goal for both fundamental and applied quantum science. To this end, a promising approach is the stabilization of nonclassical features in the presence of dissipation, by means

Reconciliation of quantum local master equations with thermodynamics

open access: yesNew Journal of Physics, 2018
The study of open quantum systems often relies on approximate master equations derived under the assumptions of weak coupling to the environment. However when the system is made of several interacting subsystems such a derivation is in many cases very ...

Historical foreword: Jean Dalibard, the magneto-optical trap, and the ascent of physics with cold atomic gases

open access: yesComptes Rendus. Physique
I present my personal perspective on the importance of the invention by Jean Dalibard of the magneto-optical trap (MOT), which has for many years been the “workhorse” of the field of laser cooling and cold atomic gases.

Entropy Production Associated with Aggregation into Granules in a Subdiffusive Environment

open access: yesEntropy, 2018
We study the entropy production that is associated with the growing or shrinking of a small granule in, for instance, a colloidal suspension or in an aggregating polymer chain. A granule will fluctuate in size when the energy of binding is comparable to

ON FREE CONVECTION HEAT TRANSFER FROM VERTICAL PLATE – PROPOSITION OF A NEW MODEL

open access: yesTASK Quarterly, 2016
The free convection heat transfer from an isothermal vertical plate in open space is investigated theoretically. In contrast to conventional approaches we use neither boundary layer nor self-similarity concepts.

Daemonic ergotropy: enhanced work extraction from quantum correlations

open access: yesnpj Quantum Information, 2017
Quantum thermodynamics: Quantum correlations are key for work extraction! A strong connection exists between the ability of a quantum system to perform thermodynamic work and the amount of quantum correlations that are set in its physical configuration ...

Welcome to Atoms: A New Open Access Journal

open access: yesAtoms, 2012
There is no doubt that it is an exciting time to be studying quantum properties of atoms, molecules, and nuclei. Increasingly deep connections between long-established fields: “atomic physics”, “molecular physics”, “chemical physics”, “nuclear physics”, “

Complete phase retrieval of photoelectron wavepackets

open access: yesNew Journal of Physics, 2020
Coherent, broadband pulses of extreme ultraviolet light provide a new and exciting tool for exploring attosecond electron dynamics. Using photoelectron streaking, interferometric spectrograms can be generated that contain a wealth of information about ...

Entanglement scaling at first order quantum phase transitions

open access: yesNew Journal of Physics, 2018
First order quantum phase transitions (1QPTs) are signalled, in the thermodynamic limit, by discontinuous changes in the ground state properties. These discontinuities affect expectation values of observables, including spatial correlations.

Laboratory Transition-rate Measurement of the Coronal Intercombination Line of Ar xv by Time-resolved Laser Spectroscopy

open access: yesThe Astrophysical Journal
The extreme-ultraviolet emission line (424 Å) of the intercombination 1 s ^2 2 s ^2 ^1 S _0 –1 s ^2 2 s 2 p ^3 P _1 transition of Ar xv can potentially characterize the electron temperature of astrophysical plasma.
