Using methods of coupling we analyze two models of card shuffling, the random transposition and the random-to-random process, to find minimal coupling times. Disregarding the rank and suit on the standard playing cards we are familiar with, we focus only on the color; specifically, we consider decks where half the cards are white and half are black. We define the total gaps on a pair of decks, ...

We study the effective field theory of a weakly coupled 3+1d gauged φ type model at high temperature. Our model has 4N real scalars (N complex Higgs doublets) and a gauge group SU(2) which is spontaneously broken by a nonzero scalar field vev at zero temperature. We find, for sufficiently large N , that the transition from the high temperature symmetry restoring phase to the low temperature pha...

The central thesis explored in this paper is that parallel model checking is easily achieved through compositional methods. This may strike the reader as being self-evident. Nevertheless, it does not appear to have been considered before. The justification comes from the following observations: (1) the efficacy of a parallel program is inversely proportional to the amount of synchronization and...

| Crosstalk noise in long interconnections is studied based on capacitive coupling and inductive coupling. It is shown that pulse noise is induced due to inductive coupling in heterogeneous insulators. The pulse noise becomes predominant noise factor on the condition that lines become longer, line resistance become lower, the signal raising time becomes faster and dielectric constant of materia...

We demonstrate strong coupling between molecular excited states and surface plasmon modes of a slit array in a thin metal film. The coupling manifests itself as an anticrossing behavior of the two newly formed polaritons. As the coupling strength grows, a new mode emerges, which is attributed to long-range molecular interactions mediated by the plasmonic field. The new, molecular-like mode repe...

A dual mechanical port machine (DMPM) is used as an electrically variable transmission (EVT) in hybrid electric vehicle (HEV). In the conventional HEV, this machine is replaced by a planetary gearbox and two electric machines and makes this structure simpler. This paper presents field oriented control (FOC) for DMPM. For HEV application, drive efficiency and wide operating speed range are impor...

We investigate the relevance to the physics of underdoped YBa2Cu3O6+x and YBa2Cu4O8 of the quantum critical point which occurs in a model of two antiferromagnetically coupled planes of antiferromagnetically correlated spins. We use a Schwinger boson mean field theory and a scaling analysis to obtain the phase diagram of the model and the temperature and frequency dependence of various susceptib...

We theoretically examine behavior of superconductivity at parallel interfaces separating the domains another dominant collective excitation, such as charge density waves or spin waves. Due to their competitive coupling in a two-component Ginzburg-Landau model, suppression order parameter interfacial planes allows for nucleation (hidden) superconducting those planes. In case, we demonstrate how ...
