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…
Microsopic nuclear level densities by the shell model Monte Carlo method
Y. Alhassid, G. F. Bertsch, C. N. Gilbreth +2
The configuration-interaction shell model approach provides an attractive framework for the calculation of nuclear level densities in the presence of correlations, but the large di…
Recent Advances in the Application of the Shell Model Monte Carlo Approach to Nuclei
Y. Alhassid, M. Bonett-Matiz, A. Mukherjee +2
The shell model Monte Carlo (SMMC) method is a powerful technique for calculating the statistical and collective properties of nuclei in the presence of correlations in model space…
Collective enhancement of nuclear state densities by the shell model Monte Carlo approach
C. Özen, Y. Alhassid, H. Nakada
The shell model Monte Carlo (SMMC) approach allows for the microscopic calculation of statistical and collective properties of heavy nuclei using the framework of the configuration…
Collectivity in Heavy Nuclei in the Shell Model Monte Carlo Approach
C. Özen, Y. Alhassid, H. Nakada
The microscopic description of collectivity in heavy nuclei in the framework of the configuration-interaction shell model has been a major challenge. The size of the model space re…
Level Densities of Heavy Nuclei by the Shell Model Monte Carlo Method
Y. Alhassid, C. Özen, H. Nakada
The microscopic calculation of nuclear level densities in the presence of correlations is a difficult many-body problem. The shell model Monte Carlo method provides a powerful tech…
Signatures of phase transitions in nuclei at finite excitation energies
Y. Alhassid, C. Özen, H. Nakada
The mean-field approximation predicts pairing and shape phase transitions in nuclei as a function of temperature or excitation energy. However, in the finite nucleus the singularit…
Recent developments in the shell model Monte Carlo approach to nuclei
Y. Alhassid, A. Mukherjee, H. Nakada +1
The shell model Monte Carlo (SMMC) approach provides a powerful method for the microscopic calculation of statistical and collective nuclear properties in model spaces that are man…
Crossover from vibrational to rotational collectivity in heavy nuclei in the shell-model Monte Carlo approach
C. Özen, Y. Alhassid, H. Nakada
Heavy nuclei exhibit a crossover from vibrational to rotational collectivity as the number of neutrons or protons increases from shell closure towards midshell, but the microscopic…
Mapping the Two-Component Atomic Fermi Gas to the Nuclear Shell-Model
C. Özen, N. T. Zinner
The physics of a two-component cold fermi gas is now frequently addressed in laboratories. Usually this is done for large samples of tens to hundreds of thousands of particles. How…
Shell Model Monte Carlo method in the -formalism and applications to the Zr and Mo isotopes
C. Ozen, D. J. Dean
We report on the development of a new shell-model Monte Carlo algorithm which uses the proton-neutron formalism. Shell model Monte Carlo methods, within the isospin formulation, ha…
