Stochastic dynamics for quantum billiards: Bridging integrability, chaos, and freezing transitions [0.03%]
量子比尔利恩的随机动力学：整合定态、混沌和冻结转变

Iván R R González et al.
We present a stochastic framework for describing the transition from regular to chaotic dynamics in quantum billiards by incorporating a background scale of fluctuations in the level spacing evolution. Analytic expressions for the nearest-n...

We introduce the α-Gauss-Logistic map, a new nonlinear dynamics constructed by composing the logistic and α-Gauss maps. Explicitly, our model is given by x_{t+1}=f_{L}(x_{t})x_{t}^{-α}-⌊f_{L}(x_{t})x_{t}^{-α}⌋, where f_{L}(x_{t})=rx_{...
Dependence of Krylov complexity saturation on the initial operator and state [0.03%]

Sreeram Pg et al.
Krylov complexity, a quantum complexity measure which uniquely characterizes the spread of a quantum state or an operator, has recently been studied in the context of quantum chaos. However, the definitiveness of this measure as a chaos qua...

Through the development of a microscopic deterministic model in the framework of three-phase traffic theory, microscopic features of vehicle overacceleration, which determines the occurrence of the metastability of free traffic flow at a bo...
Convective nature of the stimulated Raman side scattering in inertial confinement fusion [0.03%]

The absolute growth of stimulated Raman side scattering (SRSS) predicted by previous theories appeared to be surprisingly absent in the recent ignition-scale direct-drive experiments with the absence attributed to different reasons. We pres...

Determining the onset of rigidity in gels is a fundamental challenge with significant practical implications across different applications. Limited-valence, or patchy-particle, systems have proven to be a valuable model to study the relatio...

For two high-dimensional datasets X and Y, with dimensionalities N_{X} and N_{Y} of order of the number of samples T, estimates of their cross-covariance will have large fluctuations. These sampling fluctuations can be studied by analyzing ...
Active stop and go motion: A strategy to improve spatial exploration and survival [0.03%]
主动式停止与移动：一种提高空间探索和生存率的策略

We consider active Brownian particles that intermittently switch between active and inactive states. Such behavior is ubiquitous at all scales, from bacteria to animals and in artificial active systems. We derive exact expressions for key t...

We apply a simple sudden-quench approximation for the unitary work strokes of a quantum Otto engine in order to provide a general analysis of its performance, applicable to arbitrary quantum models with two-body interactions. This work exte...
Soft cavity model for touch mechanoreceptors under static and sliding contact [0.03%]
静止和滑动接触下触觉机械感受器的软腔模型

P Tapie et al.
We mimic the mechanical response of touch mechanoreceptors by that of a gas cavity embedded in an elastic semicylinder, as a fingertip analog. Using tribological experiments combined with optical imaging, we measure the dynamics and deforma...
