Rotational coherence spectroscopy of molecules in helium nanodroplets: Reconciling the time and the frequency domains
Adam S. Chatterley, Lars Christiansen, Constant A. Schouder +7
Alignment of OCS, CS and I molecules embedded in helium nanodroplets is measured as a function of time following rotational excitation by a non-resonant, comparatively weak…
BKT-paired phase in coupled XY models
Giacomo Bighin, Nicolò Defenu, István Nándori +2
We study the effect of a linear tunneling coupling between 2D systems, each separately exhibiting the topological Berezinskii-Kosterlitz-Thouless (BKT) transition. In the uncoupled…
Far-from-equilibrium dynamics of angular momentum in a quantum many-particle system
Igor N. Cherepanov, Giacomo Bighin, Lars Christiansen +4
We use laser-induced rotation of single molecules embedded in superfluid helium nanodroplets to reveal angular momentum dynamics and transfer in a controlled setting, under far-fro…
Detecting composite orders in layered models via machine learning
W. Rzadkowski, N. Defenu, S. Chiacchiera +2
Determining the phase diagram of systems consisting of smaller subsystems 'connected' via a tunable coupling is a challenging task relevant for a variety of physical settings. A ge…
Variational approaches to quantum impurities: from the Fröhlich polaron to the angulon
Xiang Li, Giacomo Bighin, Enderalp Yakaboylu +1
Problems involving quantum impurities, in which one or a few particles are interacting with a macroscopic environment, represent a pervasive paradigm, spanning across atomic, molec…
Diagrammatic Monte Carlo approach to angular momentum in quantum many-particle systems
G. Bighin, T. V. Tscherbul, M. Lemeshko
We introduce a Diagrammatic Monte Carlo (DiagMC) approach to angular momentum properties of quantum many-particle systems possessing a macroscopic number of degrees of freedom. The…
