Magnetic oscillations in the Nambu-Jona-Lasinio model

The phase structure of a simple Nambu-Jona-Lasinio model has been investigated at non-zero values of mu and H, where H is an external magnetic field and mu is the chemical potential. On this basis magnetic oscillations effects were considered. It was shown that there are standard (periodic) van Alph...

description The phase structure of a simple Nambu-Jona-Lasinio model has been investigated at non-zero values of mu and H, where H is an external magnetic field and mu is the chemical potential. On this basis magnetic oscillations effects were considered. It was shown that there are standard (periodic) van Alphen-de Haas magnetic oscillations of some thermodynamical quantities, including magnetization, pressure and particle density in the NJL system. Besides, we have found non-standard, i.e. non-periodic, magnetic oscillations, since the frequency of oscillations is an H-dependent quantity. Finally, there arises an oscillating behaviour not only for thermodynamical quantities, but also for a dynamical quantity like the quark mass. (19 refs).
