We construct a nonrelativistic field theory for the second-quantized {ital N}-body system of point particles with Chern-Simons interactions. Various properties of this model are discussed: its… (More)

A gauged, nonlinear Schroedinger equation in two spatial dimensions is considered. This equation describes nonrelativistic matter interacting with Chern-Simons gauge fields. We find explicit static,… (More)

An attempt is made to clarify the quantum theory of the ''slow-rollover'' phase transition which characterizes the new inflationary universe model. We discuss the theory of the upside-down harmonic… (More)

The goal of Project ACCESS is to create novel technologies that will enhance the quality of life of people with cognitive disabilities. Specifically, we investigate the use of assisted cognition as a… (More)

Standing wave patterns that arise on the surface of ferrofluids by (single frequency) parametric forcing with an ac magnetic field are investigated experimentally. Depending on the frequency and… (More)

We present N-body simulations of a new class of self-interacting dark matter models, which do not violate any astrophysical constraints due to a non-power-law velocity dependence of the transfer… (More)

We present a self-consistent calculation of the finite-temperature effective potential for $\ensuremath{\lambda}{\ensuremath{\varphi}}^{4}$ theory, using the composite operator effective potential in… (More)

Vortex solitons of the planar, gauged nonlinear Schroedinger equation are quantized semiclassically in the presence of an external magnetic field.

The nonlinear planar Schroedinger equation with additional coupling to non-Abelian Chern-Simons gauge fields possesses static, zero-energy solutions that satisfy self-dual equations. When the… (More)

We show that excitations in a recently proposed gauge theory for anyons on a line in fact do not obey anomalous statistics. On the other hand, the theory supports novel chiral solitons. Also we… (More)
