Spectrum and wave functions of excited states in lattice gauge theory [PDF]

, 2008
We suggest a new method to compute the spectrum and wave functions of excited states. We construct a stochastic basis of Bargmann link states, drawn from a physical probability density distribution and compute transition amplitudes between stochastic ...

Transparent Topological Meta‐Diplexer via Tightly Confined Valley Surface States

Advanced Science, EarlyView.
An optically transparent topological metasurface supporting tightly confined valley surface states enables robust and flexible wave routing in an ultrathin platform. A compact transparent meta‐diplexer with spatially and spectrally separated channels is realized, while communication experiments verify high‐fidelity signal transmission, opening new ...

Generalized honeycomb torus is Hamiltonian

, 2004
Generalized honeycomb torus is a candidate for interconnection network architectures, which includes honeycomb torus, honeycomb rectangular torus, and honeycomb parallelogramic torus as special cases. Existence of Hamiltonian cycle is a basic requirement

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Bifurcations for Hamiltonian systems

Advanced Nonlinear Studies
Our assumptions and results include the following special versions: for a topological space Λ and H∈C(Λ×S1×R2n) $H\in C\left({\Lambda}{\times}{S}^{1}{\times}{\mathbb{R}}^{2n}\right)$ , S1=R/Z ${S}^{1}=\mathbb{R}/\mathbb{Z}$ , suppose that each H(λ, t, ⋅)

Calculation of modified Hamiltonian in Sage

Discrete and Continuous Models and Applied Computational Science
The algebraic properties of difference approximations of Hamiltonian systems are investigated. Symplectic schemes exactly preserve linear and quadratic integrals by virtue of Cooper's theorem, but not the total mechanical energy of nonlinear systems ...

Multiphoton Quantum Reservoirs For Robust Multidimensional Computing

Advanced Science, EarlyView.
Projective measurements reveal hidden multidimensional quantum networks within classical multiphoton fields, enabling robust quantum reservoirs for room‐temperature quantum simulation, prediction, and information processing. These networks transform noisy classical photonic platforms into scalable quantum computational architectures.

Power oscillation suppression strategy of VSG based on finite‐time Hamiltonian method

IET Power Electronics
In order to improve the stability of the virtual synchronous generator (VSG) system and suppress the power oscillation, a power oscillation suppression strategy of VSG based on the finite‐time Hamiltonian method is proposed in this paper.
