Rotational excitation of molecules in the regime of strong ro-vibrational coupling: Comparison between an optical centrifuge and a transform-limited pulse

J. M. García-Garrido, V. Milner, C. P. Koch +1 more·Dec 10, 2025

We investigate theoretically the ability of an optical centrifuge - a laser pulse whose linear polarization is rotating at an accelerated rate, to control molecular rotation in the regime when the rigid-rotor approximation breaks down due to coupling...

Exceptional points of arbitrary high orders induced by non-Markovian dynamics

Timofey T. Sergeev, Evgeny S. Andrianov, Alexander A. Zyablovsky·Dec 10, 2025

Exceptional points are singularities in the spectrum of non-Hermitian systems in which several eigenvectors are linearly dependent and their eigenvalues are equal to each other. Usually it is assumed that the order of the exceptional point is limited...

Subradiant collective states for precision sensing via transmission spectra

Diego Zafra-Bono, Oriol Rubies-Bigorda, Susanne F. Yelin·Dec 9, 2025

When an ensemble of quantum emitters interacts with a common radiation field, their emission becomes collective, giving rise to superradiant and subradiant states, characterized by broadened and narrowed linewidths. In this work, we propose to harnes...

Fluctuation-Induced Supersolidity at the Superfluid-Solid Interface

Baptiste Coquinot, Ragheed Alhyder, Alberto Cappellaro +1 more·Dec 9, 2025

Supersolidity, combining superfluid and crystalline orders, has been realized in dipolar Bose-Einstein condensates by tuning interatomic interactions. Here we show that supersolidity can also emerge from mode coupling at a superfluid-solid interface,...
