Extracting spectra in the shell model Monte Carlo method using imaginary-time correlation matrices
Y. Alhassid, M. Bonett-Matiz, C. N. Gilbreth +1
Conventional diagonalization methods to calculate nuclear energy levels in the framework of the configuration-interaction (CI) shell model approach are prohibited in very large mod…
Circumventing the odd particle-number sign problem in the shell model Monte Carlo
Y. Alhassid, P. Fanto, C. Özen
The shell model Monte Carlo (SMMC) method is a powerful method for calculating exactly (up to statistical errors) thermal observables and statistical properties of atomic nuclei. H…
Pseudogap effects in the strongly correlated regime of the two-dimensional Fermi gas
S. Ramachandran, S. Jensen, Y. Alhassid
The two-species Fermi gas with attractive short-range interactions in two spatial dimensions provides a paradigmatic system for the understanding of strongly correlated Fermi super…
Nuclear level densities: from empirical models to microscopic methods
Y. Alhassid
The level density is among the most important statistical nuclear properties. It appears in Fermi's golden rule for transition rates and is an important input to the Hauser-Feshbac…
Low-energy enhancement in the magnetic dipole -ray strength functions of heavy nuclei
P. Fanto, Y. Alhassid
A low-energy enhancement (LEE), observed experimentally in the -ray strength function (SF) describing the decay of compound nuclei, would have profound effects on -process…
Strong enhancement of level densities in the crossover from spherical to deformed neodymium isotopes
M. Guttormsen, Y. Alhassid, W. Ryssens +19
Understanding the evolution of level densities in the crossover from spherical to well-deformed nuclei has been a long-standing problem in nuclear physics. We measure nuclear level…
