摘要：Spin Hamiltonians in condensed matter and quantum sensing typically utilize pairwise or two-body interactions between constituents in the material or ensemble. However, there is growing interest in exploring more general n-body interactions for n > 2. In this study, we realized an effective n = 3-body Hamiltonian interaction using an ensemble of laser-cooled atoms in a high-finesse optical cavity with the pseudospin 1/2 encoded by two atomic momentum states. We applied two dressing tones that ...

摘要：The environmental burden of vapor compression refrigeration has driven interest in alternatives. Caloric refrigeration cycles offer a path forward, but most rely on solid-state materials with limited temperature lift, low performance, and poor fluidity, which hinder scalability. We introduce a liquid-phase dipolarcaloric refrigeration cycle utilizing endothermic dissolution of nitrate-based salts regenerated through electrodialysis. This cycle achieves large adiabatic temperature changes and h...

摘要：Topological phases of matter are of both fundamental and practical interest. In this study, we implemented both equilibrium and nonequilibrium higher-order topological phases using a two-dimensional programmable superconducting quantum processor. Quantum programming of nonequilibrium higher-order topological phases was achieved by constructing quantum circuits comprising >50 cycles of Floquet operators on a six-by-six qubit array. Additionally, we introduce a universal approach based on measur...
