Author(s): Maxim Sukharev The ultrafast nonlinear optical response of molecular ensembles is fundamentally altered under strong light-matter coupling. To rigorously isolate the genuine many-body contributions, an exact time-domain field-subtraction protocol is developed within a fully nonperturbative Maxwell-Liouville framew… [Phys. Rev.

Author(s): G. A. Bougas, A. Vardi, H. R. Sadeghpour, C. Chin, and S. I. Mistakidis We map the phase diagram of a two-mode atom-molecule Bose-Einstein condensate with Fano-Feshbach and coherent three-body recombination (cTBR) terms. The standard second-order phase transition observed as the molecular energy is tuned through the Fano-Feshbach resonance is replaced by a first-order t… [Phys. Rev.

Author(s): DinhDuy Vu, Dominik S. Kufel, Jack Kemp, Lode Pollet, Chris R. Laumann, and Norman Y. Yao Quantum spin liquids are elusive long-range entangled states. Motivated by experiments in Rydberg quantum simulators, recent excitement has centered on the possibility of dynamically preparing a state with quantum spin-liquid correlations even when the ground-state phase diagram does not exhibit suc… [Phys.

Author(s): Shulin Wang, Jiawei He, Zhiyuan Yang, Stefano Longhi, and Peng Xue Non-Hermitian systems exhibit anomalous scaling, a striking departure from conventional bulk laws, rooted in the non-Hermitian skin effect (NHSE). Here, we experimentally uncover this scaling and demonstrate its active control in a temporal photonic lattice. By tracking the real-time evolution of al… [Phys. Rev.

Author(s): Sam Foster, Olivier Bleu, Jesper Levinsen, and Meera M. Parish We study the canonical problem of a Fermi gas interacting with a weakly repulsive Bose-Einstein condensate at zero temperature. To explore the quantum phases across the full range of boson-fermion interactions, we construct a versatile variational Ansatz that incorporates pair correlations and corre… [Phys. Rev.

Author(s): Chong-Xiao Chen, Zheng-Wei Zhou, Han Pu, and Xi-Wang Luo The interplay between topology and nonlinearity represents a central challenge in modern physics. Here, we investigate this interplay by considering a synthetic Su-Schrieffer-Heeger lattice with all-to-all nonlocal interactions. We find that the distinctive nonlinearity maintains an effective chiral… [Phys. Rev. Lett. 137, 073803] Published Fri Aug 14, 2026

Author(s): Aileen A. T. Durst, Seth T. Rittenhouse, H. R. Sadeghpour, and Matthew T. Eiles We present a framework for treating mesoscopic anisotropic and nonadditive impurity–bath interactions, ubiquitous in realistic quantum impurity problems, which are often neglected in conventional approaches relying on additive, spherically symmetric pseudopotentials. To illustrate this general appro… [Phys. Rev. Lett. 137, 073401] Published Thu Aug 13...
