Pure SU(3) glue theories exhibit a decon ning phase transition at a nonzero temperature, Tc.
Using lattice measurements of the pressure, we develop a simple matrix model to describe the
transition r...
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...
Efficient Algorithm for Asymptotics-Based CI and Electronic Structure of Transition Metal Atoms
Efficient Algorithm Asymptotics-Based CI Electronic Structure Transition Metal Atoms
2010/10/19
Asymptotics-based CI methods1 are a class of Configuration-Interaction (CI) methods for atoms which reproduce,at fixed finite subspace dimension, the exact Schr¨odinger eigenstates in the limit of fix...
Precision measurement of the 5 2S1/2 - 4 2D5/2 quadrupole transition isotope shift between 88Sr+ and 86Sr+
Precision measurement 88Sr+ 86Sr+
2010/10/21
We have measured the isotope shift of the narrow quadrupole-allowed 52S1=2 - 42D5=2 transition
in 86Sr+ relative to the most abundant isotope 88Sr+. This was accomplished using high-resolution laser ...
