Author(s): Botao Wang, Monika Aidelsburger, Jean Dalibard, André Eckardt, and Nathan Goldman Optical box traps offer new possibilities for quantum-gas experiments. Building on their exquisite spatial and temporal control, we propose to engineer system-reservoir configurations using box traps, in view of preparing and manipulating topological atomic states in optical lattices. First, we cons… [Phys. Rev. Lett. 132, 163402] Published Tue Apr...

Author(s): Gianluca Passarelli, Xhek Turkeshi, Angelo Russomanno, Procolo Lucignano, Marco Schirò, and Rosario Fazio We study the properties of a monitored ensemble of atoms driven by a laser field and in the presence of collective decay. The properties of the quantum trajectories describing the atomic cloud drastically depend on the monitoring protocol and are distinct from those of the average density matrix. By… [Phys. Rev.

Author(s): R. J. Lewis-Swan, J. C. Zuñiga Castro, D. Barberena, and A. M. Rey We theoretically investigate prospects for the creation of nonclassical spin states in trapped ion arrays by coupling to a squeezed state of the collective motion of the ions. The correlations of the generated spin states can be tailored for quantum-enhanced sensing of global or differential rotatio… [Phys. Rev. Lett. 132, 163601] Published Mon Apr 15, 2024

Author(s): Matija Tečer, Marco Di Liberto, Pietro Silvi, Simone Montangero, Filippo Romanato, and Giuseppe Calajó One-dimensional confinement in waveguide quantum electrodynamics (QED) plays a crucial role to enhance light-matter interactions and to induce a strong quantum nonlinear optical response. In two or higher-dimensional settings, this response is reduced since photons can be emitted within a larger pha… [Phys. Rev. Lett. 132, 163602...

Author(s): Sebastian C. Carrasco, Michael H. Goerz, Svetlana A. Malinovskaya, Vladan Vuletić, Wolfgang P. Schleich, and Vladimir S. Malinovsky Considering the unique energy level structure of the one-axis twisting Hamiltonian in combination with standard rotations, we propose the implementation of a rapid adiabatic passage scheme on the Dicke state basis. The method permits to drive Dicke states of the many-atom system into entangled state… ...

Author(s): Wei Chen, Yuan Liu, An-Zhuo Yu, Han Cao, Wei Hu, Wen Qiao, Lin-Sen Chen, and Yan-Qing Lu In this Letter, we explore the intersection of chirality and recently discovered toroidal spatiotemporal optical vortices (STOVs). We introduce “photonic conchs” theoretically as a new type of toroidal-like state exhibiting geometrical chirality, and experimentally observe these wave packets with co… [Phys. Rev.
