Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover
Advanced Science, EarlyView.This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Unitary representations of knot groups
Topology, 1993 The paper is a part of the author's program to develop a generalization of Casson's invariant by using \(\text{SU}(n)\) instead of \(\text{SU}(2)\). The first step in such a program is to define an analog of Casson's invariant of knots. The definition of these invariants and the derivation of their properties is given in [the author and \textit{D.

Performance Rate Analysis in Photovoltaic Solar Plants by Machine Learning
Advanced Energy and Sustainability Research, EarlyView.Thermal imaging and deep learning are combined to detect faults in photovoltaic panels inspected by autonomous vehicles. A robust pipeline classifies panel defects from aerial thermograms using a convolutional neural network, supporting both real‐time and offline analysis.

Angular Gelfand--Tzetlin Coordinates for the Supergroup UOSp(k_1/2k_2)
, 2002 We construct Gelfand--Tzetlin coordinates for the unitary orthosymplectic supergroup UOSp(k_1/2k_2). This extends a previous construction for the unitary supergroup U(k_1/k_2). We focus on the angular Gelfand--Tzetlin coordinates, i.e.

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future
Advanced Intelligent Systems, EarlyView.Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

Unitary Groups: Representations and Decompositions [PDF]
Reviews of Modern Physics, 1966 An elementary account is given of the representation theory for unitary groups. We review the basic definitions and the construction of irreducible representations using tensor methods, and indicate the connection to the infinitesimal approach. Special attention has been given to the detailed procedure to obtain Clebsch-Gordan series and to the problem

Reprogrammable, In‐Materia Matrix‐Vector Multiplication with Floppy Modes
Advanced Intelligent Systems, EarlyView.This article describes a metamaterial that mechanically computes matrix‐vector multiplications, one of the fundamental operations in artificial intelligence models. The matrix multiplication is encoded in floppy modes, near‐zero force deformations of soft matter systems.

Distinguished representations for unitary groups [PDF]
Pacific Journal of Mathematics, 1997 This paper is concerned with a unitary group \(G=U(2r,2r)\) of a quadratic extension \(K/k\) of number fields, and a symplectic subgroup \(H=Sp(r,r,D)\) associated with a quaternion algebra \(D\). It is observed that Fourier type local orbital integrals \(\int f(u^{-1}\xi\theta(u))\psi(u)du\) for some characters \(\psi\not=1\) of a unipotent subgroup \(

A Field Programmable Gate Array‐Assisted Optoelectronic Emulator for Photonic Neuromorphic Computing
Advanced Intelligent Systems, EarlyView.This work presents a hybrid optoelectronic architecture using field‐programmable‐gate‐array‐controlled optical components for multiplication operations. Data are encoded via electro‐optic modulator, weights are programmed via a variable optical attenuator, and results are detected by a photodetector.
