Exact density functional theory with the density matrix renormalization group
density functional theory density matrix renormalization group electronic structure models
2011/8/17
Abstract: Combining density functional theory with controlled numerical methods for strongly correlated systems could greatly extend the range of both. We use the density matrix renormalization group ...
K-shell photoionization of Nickel ions using R-matrix
atomic data atomic processes line formation X-rays
2011/8/17
Abstract: We present R-matrix calculations of photoabsorption and photoionization cross sections across the K edge of the Li-like to Ca-like ions stages of Ni. Level-resolved, Breit-Pauli calculations...
Optical Excitation and Decay Dynamics of Ytterbium Atoms Embedded in a Solid Neon Matrix
Ytterbium Atoms Embedded Optical Excitation and Decay Dynamics
2011/9/2
Neutral ytterbium atoms embedded in solid neon qualitatively retain the structure of free atoms. Despite the atom-solid interaction, the 6s6p 3P0 level is found to remain metastable with its lifetimes...
Tensorial form and matrix elements of the relativistic nuclear recoil operator
Isotope shifts, mass shift, relativistic nuclear recoil
2011/8/31
Within the lowest-order relativistic approximation (∼ v2/c2) and to first order in me/M, the tensorial form of the relativistic corrections of the nuclear recoil Hamiltonian is derived, opening ...
On the structure of the S-matrix in general boundary quantum field theory in curved space
the S-matrix quantum field theory
2010/12/23
We use the general boundary formulation (GBF) of quantum field theory to compute the S-matrix for a general interacting scalar field in curved spacetime. This S-matrix is obtained as the asymptotic li...
Chiral fermions and the standard model from the matrix model compactified on a torus
Chiral fermions standard model matrix model compactified
2011/1/14
It is shown that the IIB matrix model compactified on a six-dimensional torus with a nontrivial topology can provide chiral fermions and matter content close to the standard model on our four-dimensio...
Constraining the mixing matrix for Standard Model with four generations: time dependent and semi-leptonic CP asymmetries in $B_d^0$, $B_s$ and $D^0$
Constraining the mixing matrix Standard Model four generations: time dependent semi-leptonic CP asymmetries $B_d^0$, $B_s$ $D^0$
2011/1/6
Using existing experimental information from K, B and D decays as well as electroweak precision tests and oblique parameters, we provide constraints and correlations on the pa-
