Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Approximation and computation for the linear and nonlinear eigenvalue problems in photonic crystals
光子晶体 线性非线性特征值问题 近似 计算
2023/5/15
In this talk, we discuss the approximation and computation for the linear and nonlinear eigenvalue problems in photonic crystals. We discretize the shifted Maxwell operator with edge finite elements a...
Absence of sign problem in the (saddle point approximation of the) nilpotency expansion of QCD at finite chemical potential
nilpotency expansion finite chemical potential
2011/1/13
We have developed a method to derive the (approximate) quark contribution to the fermion free
energy of QCD on a lattice, at finite temperature and chemical potential, with Kogut-Susskind
fermions i...
A qubit strongly-coupled to a resonant cavity: asymmetry of the spontaneous emission spectrum beyond the rotating wave approximation
spontaneous emission spectrum vacuum Rabi splitting qubit strongly-coupled to a cavity
2010/10/20
We investigate the spontaneous emission spectrum of a qubit in a lossy resonant cavity. We
use neither the rotating-wave approximation nor the Markov approximation. The qubit-cavity
coupling strengt...
