Suppressing nonperturbative gauge errors in the thermodynamic limit using local pseudogenerators [PDF]

open access: yesCommunications Physics
With recent progress in quantum simulations of lattice-gauge theories, it is becoming a pressing question how to reliably protect the gauge symmetry that defines such models.

Analytic Design of Accelerated Adiabatic Gates in Realistic Qubits: General Theory and Applications to Superconducting Circuits [PDF]

open access: yesPRX Quantum, 2021
Shortcuts to adiabaticity is a general method for speeding up adiabatic quantum protocols, and has many potential applications in quantum information processing. Unfortunately, analytically constructing shortcuts to adiabaticity for systems having complex interactions and more than a few levels is a challenging task.

Calculation of Rotor’s Current and MMF in a Squirrel Cage Induction Machine [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
This paper presents a method for calculation of bar’s currents and its magneto motive force (MMF) in a squirrel cage induction machine. For this propose, at first multiple coupled circuit modeling of cage induction motor is introduced.

Interfacial spin-flip-generated charge pumping

open access: yesPhysical Review Research, 2021
Precessing magnetization is known to generate and inject pure spin currents to adjacent materials by the spin pumping effect. However, the generation of the pure spin current is the only case of the spin pumping at the spin-conserving interface.

Towards Distributed Stability Analytics of Dynamic Power Systems: A Phasor-Circuit Theory Perspective [PDF]

open access: yes2019 Chinese Control Conference (CCC), 2019
With the rapid development of renewable and distributed energies, the underlying dynamics of power systems are no longer dominated by large synchronous generators, but by numerous dynamic components with heterogeneous characteristics. In such a situation, the traditional stability analysis method may fail due to the challenges of heterogeneity and ...

A NEW WIDE-STOPBAND LOW-PASS FILTER WITH GENERALIZED COUPLED-LINE CIRCUIT AND ANALYTICAL THEORY [PDF]

open access: yesProgress In Electromagnetics Research, 2011
A generalized coupled-line circuit is introduced to construct a wide-stopband low-pass fllter in this paper. This circuit conflguration includes two-section coupled lines and a connected transmission-line stub. Due to the symmetry of this proposed structure, closed-form equations for scattering parameters are investigated.

Second-Harmonic Nonlinear Electrochemical Impedance Spectroscopy: Part I. Analytical Theory and Equivalent Circuit Representations for Planar and Porous Electrodes

open access: yesJournal of The Electrochemical Society, 2023
Analytical theory for second harmonic nonlinear electrochemical impedance spectroscopy (2nd-NLEIS) of planar and porous electrodes is developed for interfaces governed by Butler-Volmer kinetics, a Helmholtz (mainly) or Gouy-Chapman (introduced) double layer, and transport by ion migration and diffusion.

Comparing habitat suitability and connectivity modeling methods for conserving pronghorn migrations. [PDF]

open access: yesPLoS ONE, 2012
Terrestrial long-distance migrations are declining globally: in North America, nearly 75% have been lost. Yet there has been limited research comparing habitat suitability and connectivity models to identify migration corridors across increasingly ...
