The first three dynamic multipole polarizabilities for the ground state of hydrogen, helium, hydride ion, and positronium hydride PsH have been computed using the variational Monte Carlo ~VMC! method and explicitly correlated wave functions. Results for the static dipole polarizability by means of the diffusion Monte Carlo method and the finite field approach show the VMC results to be quite ac...

The monochromatic scheme adopted in the tau-charm factories uses a large dispersion at interaction point to obtain a very high collision energy resolution. Due to the presence of dispersion, however, the beambeam interaction induces the synchro-betatron coupling. Even if in the linear regime, it can lead to potentially serious effects. One of the most serious is the rapid decrease of the energy...

The first three dynamic multipole polarizabilities for the ground state of hydrogen, helium, hydride ion, and positronium hydride PsH have been computed using the variational Monte Carlo (VMC) method and explicitly correlated wave functions. Results for the static dipole polarizability by means of the diffusion Monte Carlo (DMC) method and the finite field approach show the VMC results to be qu...

The most exciting result of the last decade has been the growing evidence that neutrinos are massive. The V-A structure of the electroweak theory requires only left handed and therefore massless neutrinos. Observation of neutrino mass is therefore in direct conflict with the Standard Model. The most important result, indicating that neutrinos do oscillate and therefore have to have mass, comes ...

Models-3, a flexible software framework, and its Community Multiscale Air Quality (CMAQ) modeling system form a powerful third generation air quality modeling and assessment tool designed to support air quality modeling applications ranging from regulatory issues to science inquiries on atmospheric science processes. The CMAQ system can address tropospheric ozone, acid deposition, visibility, f...

We study a fully inertial model of a martensitic phase transition in a one-dimensional crystal lattice with long-range interactions. The model allows one to represent a broad range of dynamic regimes, from underdamped to overdamped. We systematically compare the discrete model with its various continuum counterparts including elastic, viscoelastic and viscosity-capillarity models. Each of these...

By exploiting differences in muon lifetimes it is possible to distinguish ν µ from ν µ charged current interactions in underground neutrino detectors. Such observations would be a useful tool in understanding the source of the atmospheric neutrino anomaly.

We study the Fermi liquid properties of the cold atomic dipolar Fermi gases with the explicit dipolar anisotropy using perturbative approaches. Due to the explicit dipolar anisotropy, Fermi surfaces exhibit distortions of the dr2−3z2 type in three dimensions and of the dx2−y2 type in two dimensions. The fermion self-energy, effective mass, and Fermi velocity develop the same anisotropy at the H...

Molecular fractionation with conjugate caps (MFCC) method is introduced for the efficient estimation of quantum mechanical (QM) interaction energies between nanomaterial (carbon nanotube, fullerene, and graphene surface) and ligand (charged and neutral). In the calculations, nanomaterials are partitioned into small fragments and conjugated caps that are properly capped, and the interaction ener...

In this paper we examine the effect of introducing an Electromagnetic metamaterial into a Travelling Wave structure to mediate inverse Cherenkov acceleration. Electromagnetic metamaterials are artificial materials that consist of macroscopic structures that yield an effective permittivity and permeability less than zero. The properties of metamaterials are highly frequency dependent and give ri...
