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…
Collective rotational cat states of molecules in microwave cavities
Volker Karle, Florian Kluibenschedl, Mikhail Lemeshko +1
We show theoretically that an ensemble of polar molecules coupled to a microwave cavity supports hybrid rotational-photonic cat states. The cavity couples to a symmetric rotor in t…
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.…
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…
The R-index: A universal metric for evaluating OAM content and mode purity in optical fields
Monika Bahl, Georgios M. Koutentakis, Mikhail Maslov +4
Despite its pivotal role in optical manipulation, high-capacity communications, and quantum information, a general measure of orbital angular momentum (OAM) in structured light rem…
Phenomenological model of decaying Bose polarons
Ragheed Alhyder, Georg M. Bruun, Thomas Pohl +2
Cold atom experiments show that a mobile impurity particle immersed in a Bose-Einstein condensate forms a well-defined quasiparticle (Bose polaron) for weak to moderate impurity-bo…
Tunable Field-Linked -wave Interactions in Dipolar Fermi Mixtures
Jing-Lun Li, Georgios M. Koutentakis, Mateja Hrast +3
Spin mixtures of degenerate fermions are a cornerstone of quantum many-body physics, enabling superfluidity, polarons, and rich spin dynamics through -wave scattering resonances…
Bottom-up Analysis of Ro-Vibrational Helical Dichroism
Mateja Hrast, Georgios M. Koutentakis, Mikhail Maslov +1
Helical dichroism (HD) is a proposed method for the resolution of molecular chirality, employing the orbital angular momentum (OAM) of light. Going beyond the conventional assumpti…
Domain-Wall Ferroelectric Polarons in a two-dimensional Rotor Lattice Model
Florian Kluibenschedl, Georgios M. Koutentakis, Ragheed Alhyder +1
We demonstrate the formation of ferroelectric domain-wall polarons in a minimal two-dimensional lattice model of electrons interacting with rotating dipoles. Along the domain-wall,…
Quantum rotor in a two-dimensional mesoscopic Bose gas
Michał Suchorowski, Alina Badamshina, Mikhail Lemeshko +2
We investigate a molecular quantum rotor in a two-dimensional Bose-Einstein condensate. The focus is on studying the angulon quasiparticle concept in the crossover from few- to man…
Massive Dirac-Pauli physics in lead-halide perovskites
Abhishek Shiva Kumar, Mikhail Maslov, Mikhail Lemeshko +2
In standard quantum electrodynamics (QED), the so-called non-minimal (Pauli) coupling is suppressed for elementary particles and has no physical implications. Here, we show that th…
Observation of Analogue Dynamic Schwinger Effect and Non-Perturbative Light Sensing in Lead Halide Perovskites
Dusan Lorenc, Artem G. Volosniev, Ayan A. Zhumekenov +5
Dielectric breakdown of physical vacuum (Schwinger effect) is the textbook demonstration of compatibility of Relativity and Quantum theory. Although observing this effect is still…
Theory of angular momentum transfer from light to molecules
Mikhail Maslov, Georgios M. Koutentakis, Mateja Hrast +2
We present a theory describing interaction of structured light, such as light carrying orbital angular momentum, with molecules. The light-matter interaction Hamiltonian we derive…
