Saad Zaheer 1, Sahand Jamal Rahi 1, Thorsten Emig 2, 3, Robert L. Jaffe 4 Physical Review A: Atomic, Molecular and Optical Physics 82 (2010) 052507 We study the electromagnetic Casimir interaction of a compact object contained inside a closed cavity of another compact object. We express the interaction energy in terms of the objects’ scattering matrices and translation matrices that relate the coordinate […]

Thorsten Emig 1, 2 International Journal of Modern Physics A 25, 11 (2010) 2177-2195 The properties of fluctuation induced interactions like van der Waals and Casimir-Lifshitz forces are of interest in a plethora of fields ranging from biophysics to nanotechnology. Here we describe a general approach to compute these interactions. It is based on a combination of methods

We show that a parabolic cylinder, for which analytic solutions to the Helmholtz equation are available, is another case where such

E. Trizac 1, Y. Levy 2, P. G. Wolynes 3 Proceeding of the national academy of sciences 107 (2010) 2746 Biomolecular folding and function are often coupled. During molecular recognition events, one of the binding partners may transiently or partially unfold, allowing more rapid access to a binding site. We describe a simple model for this flycasting mechanism based on the

E. Bogomolny 1 Journal of Physics A Mathematical and Theoretical 43 (2010) 335102 The large N limit of mean spectral density for the ensemble of NxN sub-unitary matrices derived by Wei and Fyodorov (J. Phys. A: Math. Theor. 41 (2008) 50201) is calculated by a modification of the saddle point method. It is shown that the result

Christophe Texier 1, 2 Journal of Physics A Mathematical and Theoretical 43 (2010) 425203 Several general results for the spectral determinant of the Schrödinger operator on metric graphs are reviewed. Then, a simple derivation for the $\zeta$-regularised spectral determinant is proposed, based on the Roth trace formula. Two types of boundary conditions are studied: functions continuous at the
