Monte Carlo simulations of two-dimensional charged bosons
Quantum Monte Carlo methods are used to calculate various ground state properties of charged bosons in two dimensions, throughout the whole density range where the fluid phase is stable. Wigner…

Two-vibron bound states lifetime in a one-dimensional molecular lattice coupled to acoustic phonons
The lifetime of two-vibron bound states in the overtone region of a one-dimensional anharmonic molecular lattice is investigated. The anharmonicity, introduced within an attractive Hubbard…

Large Grain Size Dependence of Resistance of Polycrystalline Films
A qualitative behavior of grain size dependent resistance of polycrystalline films has been worked out by extending the earlier model (Volger's model) for polycrystalline films. Growth of grain…

Impurity Effects on the A1-A2 Splitting of Superfluid 3He in Aerogel
When liquid 3He is impregnated into silica aerogel a solid-like layer of 3He atoms coats the silica structure. The surface 3He is in fast exchange with the liquid on NMR timescales. The exchange…

Short time evolved wave functions for solving quantum many-body problems
The exact ground state of a strongly interacting quantum many-body system can be obtained by evolving a trial state with finite overlap with the ground state to infinite imaginary time. In this work,…

Selective Transport and Mobility Edges in Quasi-1D Systems with a Stratified Correlated Disorder
We present analytical results on transport properties of many-mode waveguides with randomly stratified disorder having long-range correlations. To describe such systems, the theory of 1D transport…

The Eight Dimensional Quantum Hall Effect and the Octonions
We construct a generalization of the quantum Hall effect where particles move in an eight dimensional space under an SO(8) gauge field. The underlying mathematics of this particle liquid is that of…

Refraction of Electromagnetic Energy for Wave Packets Incident on a Negative Index Medium is Always Negative
We analyze refraction of electromagnetic wave packets on passing from an isotropic positive to an isotropic negative refractive index medium. We definitively show that in all cases the energy is…

Ideal glass transitions in thin films: An energy landscape perspective
We introduce a mean-field model for the potential energy landscape of a thin fluid film confined between parallel substrates. The model predicts how the number of accessible basins on the energy…

Kinetics of nucleation for the decreasing rate of the new embryos growth
Kinetics of the first order phase transition is investigated. In some rather wide spread situations the property of avalanche growth of the objects of a new phase doesn't take place. This…

Solitonic transmission of Bose-Einstein matter waves
We consider a continuous atom laser propagating through a wave guide with a constriction. Two different types of transmitted stationary flow coexist. The first one coincides, at low incident current,…

Erratum: Diffusion Monte Carlo study of circular quantum dots
Several of the energies in Tables I and II of our previous paper are incorrect. Most of the errors are due to incorrectly inputting the symmetry of some of the states, others are due to incorrectly…
