Ponderomotive forces and wave dispersion: two sides of the same coin
Ponderomotive wave dispersion coin Quantum Physics
2011/8/4
Abstract: Presented here is a general view on adiabatic and resonant wave-particle interactions leading to a uniform description of nonlinear ponderomotive effects in very different environments, from...
Figure "8" gravitational-wave antenna using a superconducting-core coaxial cable: Continuity equation and its superluminal consequences
General Relativity and Quantum Cosmology(gr-qc) Quantum Physics(quant-ph)
2010/11/9
A novel gravitational-wave antenna is proposed based on the prediction that supercurrents induced by gravitational waves in a superconductor that is bent into the shape of a figure "8" will couple eff...

confinement-induced p-wave resonances s-wave interaction
2010/11/8
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partial-wave resonances in mixed dimensions. We develop two-body scattering theories in all three cases of 0D-3D, 1D...

We calculate the probability distributions of quarks in the ground state of the proton, and how
they are a ected in the presence of a constant background magnetic eld. We focus on wave functions in ...

Symmetry breaking orbital anisotropy detwinned Ba
2010/11/17
Nematicity, defined as broken rotational symmetry, has recently been observed in the competing phases in proximity to the superconducting phase in the high TC cuprates (1-2). Similarly, the new iron-b...

We show that a purely s-wave interaction in three dimensions (3D) can induce higher partialwave
resonances in mixed dimensions. We develop two-body scattering theories in all three cases of
0D-3D.

Modified Padé Approach S-Wave Charmonium Spectroscopy QCD
2010/11/9
We calculate the S-wave charmonium spectroscopy using the Hamiltonian with the non-relativistic QCD (NRQCD) potential. The logarithmic factor $\ln \mu r$, appearing in the next-to-leading order QCD lo...
Wave packet evolution in non-Hermitian quantum systems

2010/11/8
The quantum evolution of the Wigner function for Gaussian wave packets generated by a non-Hermitian Hamiltonian is investigated. In the semiclassical limit $\hbar\to 0$ this yields the non-Hermitian a...

Schrodinger equation radial equation boundary condition singular potentials
2010/10/20
The mathematical physics literatures as well as quantum mechanics textbooks on spherically symmetric potentials are enormous. Despite of these there is no unique point of view about the boundary behav...

2010/3/18
We study the use of atom interferometers as detectors for gravitational waves in the mHz - Hz frequency band, which is complementary to planned optical interferometers, such as LIGO and LISA. We descr...
Everlasting Quantum Wave: NIST Physicists Predict New Form of Soliton in Ultracold Gases（图）
Quantum Wave NIST Physicists Predict Soliton Ultracold Gases
2009/12/23
Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint ...
