Continuous quantum phase transition in the fermionic mass solutions of the Nambu-Jona-Lasinio model
Alireza Beygi, S. P. Klevansky, R. H. Lemmer
Recently quantum simulators have been constructed to investigate experimentally the most prominent theoretical four-point many-body system described by the Hubbard model. By varyin…

Relativistic PT-symmetric fermionic theories in 1+1 and 3+1 dimensions
Alireza Beygi, S. P. Klevansky, C. M. Bender
Relativistic PT-symmetric fermionic interacting systems are studied in 1+1 and 3+1 dimensions. The objective is to include non-Hermitian PT-symmetric interaction terms that give {\…
