Structure and Dynamics of Bose Polarons across the Mott-Insulator to Superfluid Transition
Ragheed Alhyder, Alessio Recati, Georg M. Bruun
A mobile impurity particle immersed in a quantum degenerate gas leads to the formation of a quasiparticle, which can serve as a sensor for its environment. Here, we develop a unifi…
First-principles theory of phonon renormalization from nonlinear electron-phonon interactions
Florian Kluibenschedl, Matthew Houtput, Jacques Tempere +3
Electron-phonon interactions renormalize phonon frequencies and lifetimes and are central to the dynamical properties of solids. While these effects are usually described within li…
Crossing the Rotational Sound Barrier in a Quantum Solvent
Baptiste Coquinot, Giacomo Bighin, Mikhail Lemeshko +1
Molecules embedded in superfluids provide an experimentally controllable platform for investigating impurity physics. Here, we investigate a driven molecule rotating in a superflui…
Optical centrifuge as a probe of strong dissipative coupling between a molecular rotor and superfluid helium
Ian MacPhail-Bartley, Sören E. Mahr, Cameron E. Peters +7
A macroscopic manifestation of superfluidity is that objects moving through liquid helium experience negligible friction below the Landau critical velocity. How this frictionless m…
Engineering SU()-Symmetric Hubbard Models with Microwave-Shielded Dipolar Molecules
Jing-Lun Li, Ragheed Alhyder, Andreas Schindewolf +3
Ultracold polar molecules provide strong, long-range interactions that microwave shielding makes tunable and nearly nuclear-spin independent, giving an emergent SU() symmetry. H…
Scale invariance of the polaron energy at the Mott-superfluid critical point
Matija Čufar, Ragheed Alhyder, C. J. Bradly +4
Continuous quantum phase transitions are characterized by an order parameter and correlation functions that are often challenging to access experimentally or in direct numerical si…
Reflections on future problems in cluster science
K. Hansen, V. V. Kresin, R. Alhyder +22
This article is a collection of contributions from speakers at the 2025 DEAMN [Dynamics of Electrons in Atomic and Molecular Nanoclusters] workshop at the Majorana Centre in Erice.…
Supercurrents in Josephson junctions with chiral molecular potentials
Oleg Kuliashov, Alberto Cappellaro, Oded Millo +3
The influence of chiral molecular potentials on phase-coherent transport in superconducting Josephson junctions is investigated. Within a Bogoliubov--de Gennes tight-binding framew…
Kerr-enhanced amplification of three-wave mixing and emergent masing regimes
Ragheed Alhyder, Rishabh Sahu, Johannes M. Fink +2
Integrated optical microresonators exploiting either second-order () or third-order () nonlinearities have become key platforms for frequency conversion, low-nois…
