Parity-violating photoproduction of pi(+/-) on the Delta resonance
Asymmetry of real - photon resonance asymmetric nonzero coupling dynamic hadron p-wave mystery hyperon in violation of the o 'hara theorem of weak radiation hyperon decay
2014/12/22
We analyze the real-photon asymmetry Aγ± for the parity-violating (PV) π± production on the Δ resonance via the reactions γ⃗+p→Δ+→π++n and γ⃗+d→Δ0+p→π-+p+p. This asymmetry is nonvanishing ...

2011/9/6
Abstract: We consider the Schr\"odinger operator $Hy=-y"+(p+q)y$ with a periodic potential $p$ plus a compactly supported potential $q$ on the real line. The spectrum of $H$ consists of an absolutely ...
The Friedrichs Model and its use in resonance phenomena
The Friedrichs Model resonance phenomena
2011/7/27
Abstract: We present here a relation of different types of Friedrichs models and their use in the description and comprehension of resonance phenomena. We first discuss the basic Friedrichs model and ...
Density Functional Resonance Theory of Unbound Electronic Systems
Density Functional Resonance Theory Electronic Systems
2011/9/14
Density Functional Resonance Theory (DFRT) is a complex-scaled version of ground-state Density Functional Theory (DFT) that allows one to calculate the resonance energies and lifetimes of metastable a...

Pseudo resonance quasi-periodic behavior stochastic threshold dynamics
2011/7/27
Abstract: Here we present a simple stochastic threshold model consisting of a deterministic slowly decaying term and a fast stochastic noise term. The process shows a pseudo-resonance, in the sense th...

2010/12/27
We briefly discuss construction of energy-dependent effective non-hermitian hamiltonians for studying resonances in open disordered systems

Far-Field Plasmonic Resonance Nano-Particle Image Velocimetry Micro Channel
2010/11/16
In this paper, a novel far-field plasmonic resonance enhanced nanoparticle-seeded Particle Image Velocimetry (nPIV) has been demonstrated to measure the velocity profile in a micro channel. Chemicall...
The low-lying even-parity states of the nucleon are explored in lattice QCD using the PACS-CS
collaboration 2+1-flavor dynamical-QCD gauge-field configurations made available through the In-ternation...

2011/1/14
We perform a non-perturbative lattice calculation of the P-wave pion-pion scattering phase in
the -meson decay channel using two flavors of maximally twisted mass fermions at pion masses

Pauli Blocking Effect on Efimov States Near Feshbach Resonance
Pauli Blocking Effect Efimov States Feshbach Resonance
2010/11/17
In this Letter we study the effect of Pauli blocking on the Efimov states in a quantum Fermi
gas and illustrate that the universal Efimov potential is altered at large distances. We obtain the univer...
Resonance clustering in wave turbulent regimes: Integrable dynamics
Resonance clustering wave turbulent regimes Integrable dynamics
2010/4/2
Two fundamental facts of the modern wave turbulence theory are 1) existence of power energy spectra in $k$-space, and 2) existence of "gaps" in this spectra corresponding to the resonance clustering. ...

Subharmonic resonance global climate solar forcing
2010/4/2
It is shown that, the wavelet regression detrended fluctuations of the monthly global temperature data (land and ocean combined) for the period 1880-2009yy, are completely dominated by one-third subha...
Theory of localization and resonance phenomena in the quantum kicked rotor
resonance phenomena quantum kicked rotor
2010/4/1
We present an analytic theory of quantum interference and Anderson localization in the quantum kicked rotor (QKR). The behavior of the system is known to depend sensitively on the value of its effecti...
We discuss stochastic resonance-like effects in the context of coupled quantum spin systems. We focus here on an information-theoretic approach and analyze the steady state quantum correlations (entan...

Intensity-field single-atom resonance fluorescence
2010/4/9
We report measurements of an intensity-field correlation function of the resonance fluorescence of a single trapped Ba+ ion. Detection of a photon prepares the atom in its ground state and we observe ...
