Quantum Monte Carlo method applied to strongly correlated dilute fermi gases with finite effective range
G. Wlazlowski, P. Magierski
We discuss the Auxiliary Field Quantum Monte Carlo (AFQMC) method applied to dilute neutron matter at finite temperatures. We formulate the discrete Hubbard-Stratonovich transforma…
Nuclear tetrahedral configurations at spin zero
Krzysztof Zberecki, Paul-Henri Heenen, Piotr Magierski
The possibility of the existence of stable tetrahedral deformations at spin zero is investigated using the Skyrme-HFBCS approach and the generator coordinate method (GCM). The stud…
Quantum Monte Carlo Simulations of the BCS-BEC Crossover at Finite Temperature
Aurel Bulgac, Joaquin E. Drut, Piotr Magierski
The Quantum Monte Carlo method for spin 1/2 fermions at finite temperature is formulated for dilute systems with an s-wave interaction. The motivation and the formalism are discuss…
The Finite Temperature Pairing Gap of a Unitary Fermi Gas by Quantum Monte Carlo Calculations
P. Magierski, G. Wlazlowski, A. Bulgac +1
We calculate the one-body temperature Green's (Matsubara) function of the unitary Fermi gas via Quantum Monte Carlo, and extract the spectral weight function using the met…
