Entanglement in a first order quantum phase transition
J. Vidal, R. Mosseri, J. Dukelsky
The phase diagram of spins 1/2 embedded in a magnetic field mutually interacting antiferromagnetically is determined. Contrary to the ferromagnetic case where a second order quantu…
Some new perspectives on pairing in nuclei
S. Pittel, J. Dukelsky
Following a brief reminder of how the pairing model can be solved exactly, we describe how this can be used to address two interesting issues in nuclear structure physics. One conc…
Pair Fluctuations in Ultra-small Fermi Systems within Self-Consistent RPA at Finite Temperature
A. Storozhenko, P. Schuck, J. Dukelsky +2
A self-consistent version of the Thermal Random Phase Approximation (TSCRPA) is developed within the Matsubara Green's Function (GF) formalism. The TSCRPA is applied to the many le…
The Density Matrix Renormalization Group in Nuclear Physics: A Status Report
S. Pittel, J. Dukelsky, S. Dimitrova +1
We report on the current status of recent efforts to develop the Density Matrix Renormalization Group method for use in large-scale nuclear shell-model calculations.
The elementary excitations of the BCS model in the canonical ensemble
G. Sierra, J. M. Roman, J. Dukelsky
We summarize previous works on the exact ground state and the elementary excitations of the exactly solvable BCS model in the canonical ensemble. The BCS model is solved by Richard…
