The thermal dynamical property of ideal gas on the noncommutative geometry in the coherent state formalism is investigated. We first evaluate the statistical interparticle potential and see that there are residual “attraction potential” between boson and residual “repulsion potential” between fermion in the high temperature limit. The characters could be traced to the fact that, the particle wi...

The program to construct minimum-uncertainty coherent states for general potentials works transparently with solvable analytic potentials. However, when an analytic potential is not completely solvable, like for a doublewell or the linear (gravitational) potential, there can be a conundrum. Motivated by supersymmetry concepts in higher dimensions, we show how these conundrums can be overcome.

We construct coherent states of the massless and massive representations of the Poincaré group. They are parameterised by points on the classical state space of spinning particles. Their properties are explored, with special emphasis on the geometrical structures on the state space.

Differences in the kinetic behavior of aldol reactions compared to aminoxylation and amination reactions are rationalized by consideration of the ratedetermining step in each case. Both autoinductive behavior and the rate-enhancing effect of additives are attributed to an effect on the enamine formation step.

We show that waveform-synthesized chirped laser fields are efficient tools for coherent harmonic control. A single harmonic order, or two harmonic orders, can be selectively enhanced by using a two-color field allowing a moderate linear chirp for each color. Different harmonic orders within a wide spectral range can be selectively enhanced by adjusting the laser parameters. Our theory bridges t...

Because noise-based correlation processing is based on equilibrium related stationary statistics, the ocean does not really provide a cooperatiing scenario for such processing. The objectives of this research is to develop array and signal processing that overcome the effects of the fluctuating ocean by essentilly developing techniques that speed up the processing to time scales shorter than th...

Coherent electronic transport in single-molecule junctions is investigated in the Coulomb blockade regime. Both the transmission phase and probability are calculated for junctions with various contact symmetries. A dramatic suppression of the Coulomb blockade peaks is predicted for junctions where multiple atomic orbitals of the molecule couple to a single electrode although the charging steps ...
