Twisted boundary conditions
WebJun 4, 1998 · Gauge theories on the torus T 2 and higher‐dimensional tori are considered. The compactness of these manifolds induces boundary conditions on path integrals, one for each compactified dimension. Gauge fixing affects these boundary conditions, causing them to be nonperiodic in certain gauges, the nonperiodicity being expressed in terms of a … WebJun 4, 1998 · Condensed matter systems are usually characterized by their response to external fields. The Kubo linear response theory is the standard theoretical tool used to analyze it. In order to obtain transport quantities with this method, we generally need to know both the eigenvalues and the eigenfunctions. This article discusses another …

WebDec 8, 2011 · We consider a planar waveguide with “twisted” boundary conditions. By twisting we mean a special combination of Dirichlet and Neumann boundary conditions. Assuming that the width of the waveguide goes to zero, we identify the effective (limiting) operator as the width of the waveguide tends to zero, establishes the uniform resolvent … http://twcp3.phys.ntu.edu.tw/lqcdjc/fjchiang/fjchiang_081114.pdf
