Local density of states above a disk—Geometrical vs thermal boundary conditions
نویسندگان
چکیده
We analytically calculate the contribution to local density of states due thermal sources in a disk-like patch within framework fluctuational electrodynamics. further introduce wavevector cutoff method approximate this contribution. compare results obtained with source and numerical exact LDOS above metal disk attained by SCUFF-EM calculations. By comparison we highlight difference resemblance geometrical boundary conditions which are both relevant for near-field scanning microscope measurements. Finally, give an outlook general lateral temperature profiles it surface profiles.

Neutralino relic density in supersymmetric GUTs with no-scale boundary conditions above the unification scale
We investigate SU(5) and SO(10) GUTs with vanishing scalar masses and trilinear scalar couplings at a scale higher than the unification scale. The parameter space of the models, further constrained by b-τ Yukawa coupling unification, consists of a common gaugino mass and of tanβ. We analyze the low energy phenomenology, finding that A-pole annihilations of neutralinos and/or coannihilations wit...
متن کاملThe Study of Some Boundary Value Problems Including Fractional Partial Differential Equations with non-Local Boundary Conditions
In this paper, we consider some boundary value problems (BVP) for fractional order partial differential equations (FPDE) with non-local boundary conditions. The solutions of these problems are presented as series solutions analytically via modified Mittag-Leffler functions. These functions have been modified by authors such that their derivatives are invariant with respect to fractional deriv...
متن کاملCasimir effect with non-local boundary conditions
Non-local boundary conditions have been considered in theoretical highenergy physics with emphasis on one-loop quantum cosmology, one-loop conformal anomalies, Bose–Einstein condensation models and spectral branes. In the present paper, for the first time in the literature, the Wightman function, the vacuum expectation values of the field square and the energy-momentum tensor are investigated f...
متن کاملBoundary conditions in local electrostatics algorithms.
We study the simulation of charged systems in the presence of general boundary conditions in a local Monte Carlo algorithm based on a constrained electric field. We first show how to implement constant-potential, Dirichlet boundary conditions by introducing extra Monte Carlo moves to the algorithm. Second, we show the interest of the algorithm for studying systems which require anisotropic elec...
متن کاملLocal Boundary Conditions in Quantum Supergravity
When quantum supergravity is studied on manifolds with boundary, one may consider local boundary conditions which fix on the initial surface the whole primed part of tangential components of gravitino perturbations, and fix on the final surface the whole unprimed part of tangential components of gravitino perturbations. This paper studies such local boundary conditions in a flat Euclidean backg...
