Quantum simulations with ultracold atoms typically create atomic wavefunctions with structures at optical length scales, where direct imaging suffers from the diffraction limit. In analogy to advances in optical microscopy for biological ap...

Qubits strongly coupled to a photonic crystal give rise to qubit-photon dressed bound states. These bound states, comprising the qubits and spatially localized photonic modes induced around the qubits, are the basis for many exotic physical...
Parametric heating in a 2D periodically-driven bosonic system: Beyond the weakly-interacting regime [0.03%]
超越弱相互作用 regimes 的二维周期驱动玻色子系统的参数加热

T Boulier et al.
We experimentally investigate the effects of parametric instabilities on the short-time heating process of periodically-driven bosons in 2D optical lattices with a continuous transverse (tube) degree of freedom. We analyze three types of pe...

The propagation of information in nonrelativistic quantum systems obeys a speed limit known as a Lieb-Robinson bound. We derive a new Lieb-Robinson bound for systems with interactions that decay with distance r as a power law, 1/r α . The ...

A curious feature of organ and organoid morphogenesis is that in certain cases, spatial oscillations in the thickness of the growing "film" are out of phase with the deformation of the slower-growing "substrate," while in other cases, the o...
A rapidly expanding Bose-Einstein condensate: an expanding universe in the lab [0.03%]
膨胀的玻色-爱因斯坦凝缩物中的宇宙学 Hawkins 机制

S Eckel et al.
We study the dynamics of a supersonically expanding ring-shaped Bose-Einstein condensate both experimentally and theoretically. The expansion redshifts long-wavelength excitations, as in an expanding universe. After expansion, energy in the...
Rapid evolution of the Photosystem II electronic structure during water splitting [0.03%]
光解水过程中光系统II电子结构的快速演化

Katherine M Davis et al.
Photosynthetic water oxidation is a fundamental process that sustains the biosphere. A Mn4Ca cluster embedded in the photosystem II protein environment is responsible for the production of atmospheric oxygen. Here, time-resolved x-ray emiss...
Broadband spectroscopy of thermodynamic magnetization fluctuations through a ferromagnetic spin-reorientation transition [0.03%]
通过铁磁自旋旋转过渡的热力学磁化波动的宽带光谱学研究

A L Balk et al.
We use scanning optical magnetometry to study the broadband frequency spectra of spontaneous magnetization fluctuations, or "magnetization noise", in an archetypal ferromagnetic film that can be smoothly tuned through a spin reorientation t...
Observability and Controllability of Nonlinear Networks: The Role of Symmetry [0.03%]
非线性网络的可观察性和可控性：对称性的角色

Andrew J Whalen et al.
Observability and controllability are essential concepts to the design of predictive observer models and feedback controllers of networked systems. For example, noncontrollable mathematical models of real systems have subspaces that influen...
Paradoxical Onset of Arrhythmic Waves from Depolarized Areas in Cardiac Tissue Due to Curvature-Dependent Instability [0.03%]
心脏组织中脱极化区域由于曲率依赖性不稳定性导致的反常心律失常起始机制

The generation of abnormal excitations in pathological regions of the heart is a main trigger for lethal cardiac arrhythmias. Such abnormal excitations, also called ectopic activity, often arise from areas with local tissue heterogeneity or...
