Geometric Phase Effects in Ultracold Chemical Reactions

open access: yesAtoms, 2019
The role of the geometric phase effect in chemical reaction dynamics has long been a topic of active experimental and theoretical investigations. The topic has received renewed interest in recent years in cold and ultracold chemistry where it was shown ...

Feshbach spectroscopy of an ultracold Rb-Cs mixture [PDF]

open access: yes, 2012
This thesis reports the observation of interspecies Feshbach resonances in an ultracold mixture of Rb and Cs atoms. A versatile combined magnetic and optical potential has been designed and constructed which is capable of bringing both $^{87}\rm{Rb}$ and

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution

open access: yesLaser &Photonics Reviews, EarlyView.
A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...

A Quantum Degenerate Mixture of $^{87}$Rb and $^{133}$Cs [PDF]

open access: yes, 2011
This thesis reports the formation of a dual-species Bose-Einstein condensate of $^{87}$Rb and $^{133}$Cs in the same trapping potential. Quantum degenerate mixtures exhibit rich physics inaccessible to single species experiments and provide an ideal ...

Microwave-shielded ultracold polar molecules [PDF]

open access: yes, 2023
Since the realization of Bose--Einstein condensates and degenerate Fermi gases, ultracold atoms with tunable interactions have become an essential platform for studying quantum many-body phenomena.

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

open access: yesExperimental Physiology, Volume 111, Issue 6, Page 3082-3098, 1 June 2026.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...

Interfacing ultracold atoms with nanomagnetic domain walls [PDF]

open access: yes, 2012
This thesis presents the first realisation of a new type of hybrid quantum device based on spintronic technology. We demonstrate an interaction between the magnetic fringing fields produced by domain walls within planar permalloy nanowires and a cloud of

Tracking Microhydration of the NaCl Rocksalt Molecule by Quantum Chemical Calculations and Penning Ionization Electron Spectroscopy in Helium Nanodroplets

open access: yesSmall Structures, Volume 7, Issue 5, May 2026.
This study combines quantum chemical calculations and high‐resolution Penning ionization electron spectroscopy in helium nanodroplets to investigate NaCl microhydration. It reveals the transition from contact to solvent‐separated ion pairs and quantifies hydration shell completion at about 34 water molecules.
