Bethe lattice solution of a model of SAW's with up to 3 monomers per site and no restriction
Bethe lattice solution model of SAW's 3 monomers per site no restriction

2010/11/23
In the multiple monomers per site (MMS) model, polymeric chains are represented by walks on
a lattice which may visit each site up to K times. We have solved the unrestricted version of this model, w...
Shell-model effective interactions calculated with chiral two- and three-nucleons forces and the Okamoto-Suzuki and Krenciglowa-Kuo iteraction methods

2011/1/6
We present calculations of the sd and sdpf shell-model effective interactions using the Krenciglowa-Kuo (KK) and the recently developed extended Krenciglowa-Kuo iteration method of Okamoto et al. (EKK...

2010/12/21
We show a different modification of Poincare algebra that also preserves the Lorentz algebra. The change begins with how boosts affect space-time in a way similar to how boosts affect the momenta in k...

We generalize the binary quantum counting algorithm of Lesovik, Suslov, and Blatter [Phys. Rev.
A 82, 012316 (2010)] to higher counting bases. The algorithm makes use of qubits, qutrits, and
qudits ...
We prove local existence and uniqueness of the Cauchy problem for a large class of tensorial second order linear hyperbolic partial differential equations with coefficients of low regularity in a suit...

The radiative capture cross sections for the 3He( ,)7Be and 3H( ,)7Li reactions are calculated in the fully microscopic Fermionic Molecular Dynamics approach using a realistic effective interaction th...
Comparing parallel and simulated tempering enhanced sampling algorithms at phase transition regimes
parallel tempering simulated tempering first-order phase transitions Ising and lattice-gas models

2010/11/19
Two important enhanced sampling algorithms, simulated (ST) and parallel (PT) tempering,are commonly used when ergodic simulations may be hard to achieve, e.g, due to a phase space separated by large f...
Gauge-invariant formulation of $N N \to N N \gamma$
Gauge-invariant formulation $N N \to N N \gamma$

2011/1/6
A complete, rigorous relativistic field-theory formulation of the nucleon-nucleon (NN)bremsstrahlung reaction is presented. The resulting amplitude is unitary as a matter of course
and it is gauge in...

An efficient order−N real-space Kubo approach is developed for the calculation of the thermal
conductivity of complex disordered materials. The method, which is based on the Chebyshev polyno-mi...

We explore the precision with which the Einstein Telescope (ET) will be able to measure the
parameters of intermediate–mass–ratio inspirals (IMRIs), i.e., the inspirals of stellar mass compact object...
An application of the variational analysis to calculate the meson spectral functions

2011/1/13
We present a new method to calculate meson spectral functions (SPFs) on the lattice based on
a variational method. Because, on a finite volume lattice, the meson SPFs have discrete spectra
only, a s...
