Effective operators from exact many-body renormalization
A. F. Lisetskiy, M. K. G. Kruse, B. R. Barrett +3
We construct effective two-body Hamiltonians and E2 operators for the p-shell by performing ab initio no-core shell model (NCSM) calculations for A=5 and A=6 nuclei and…
Aspects of quantum phase transitions
M. K. G. Kruse, H. G. Millerr, A. Plastino +1
A unified description of i) classical phase transitions and their remnants in finite systems and ii) quantum phase transitions is presented. The ensuing discussion relies on the in…
Ab-initio shell model with a core
A. F. Lisetskiy, B. R. Barrett, M. K. G. Kruse +3
We construct effective 2- and 3-body Hamiltonians for the p-shell by performing 12\hbarΩab initio no-core shell model (NCSM) calculations for A=6 and 7 nuclei and explicitly projec…
Landau-Ginzburg method applied to finite fermion systems: Pairing in Nuclei
M. K. G. Kruse, H. G. Miller, A. R. Plastino +2
Given the spectrum of a Hamiltonian, a methodology is developed which employs the Landau-Ginsburg method for characterizing phase transitions in infinite systems to identify phase…
