Glycogen phosphorylase inhibitors: A free energy perturbation analysis of glucopyranose spirohydantoin analogues
(2005)
GP catalyzes the phosphorylation of glycogen to Glc-1-P. Because of its fundamental role in the metabolism of glycogen, GP has been the target for a systematic structure-assisted design of inhibitory compounds, which could ...
The lattice free energy of QCD with clover fermions, up to three-loops
(2008)
We calculate the perturbative value of the free energy in Lattice QCD, up to three loops. Our calculation is performed using Wilson gluons and the Sheikholeslami-Wohlert (clover) improved action for fermions. The free ...
Lattice free energy with overlap fermions: A two-loop result
(2004)
We calculate the two-loop partition function of QCD on the lattice, using the Wilson formulation for gluons and the overlap-Dirac operator for fermions. Direct by-products of our result are the two-loop free energy and ...
Large Wilson loops with overlap and clover fermions: Two-loop evaluation of the b-quark mass shift and the quark-antiquark potential
(2008)
We compute, to two loops in perturbation theory, the fermionic contribution to rectangular R × T Wilson loops, for different values of R and T. We use the overlap fermionic action. We also employ the clover action, for ...
Higher loop results for the plaquette, using the clover and overlap actions
(2005)
We calculate the perturbative value of the free energy in QCD on the lattice. This quantity is directly related to the average plaquette. Our calculation is done to 3 loops using the clover action for fermions
Competing broken-symmetry and rotationally symmetric spin-singlet states in a few-electron quantum dot in a magnetic field
(2008)
On the basis of developed variational many-body approach, within a second quantized formulation, the nature of the ground state of a few-electron system in a parabolic two-dimensional (2D) quantum dot (QD) is theoretically ...
Few-electron systems in a quantum dot in a magnetic field: The Wigner molecule and paired electron phases
(2006)
We have developed a variational many-body description for few-electron systems in a parabolic quantum dot in an external magnetic field. The ground state energy of the electronic system has been theoretically investigated ...
Coulomb repulsive correlation in A3B5 semiconductor quantum dots in the presence of a magnetic field
(2006)
The ground state total and correlation energies of a negative ion-electron and electron-electron systems in a parabolic QD with standard dispersion law are theoretically investigated in an external magnetic field by a ...
Exciton-donor complexes in semiconductor quantum dots in a magnetic field: Infinite and finite potential barriers
(2008)
The binding energy of the ground state of a charged exciton-donor complex in a spherical semiconductor quantum dot with infinite and finite potential barriers as well as the oscillator strength for the optical transition ...
