Behavioral studies using personal digital devices typically produce rich longitudinal datasets of mixed data types. These data provide information about the behavior of users of these devices in real-time and in the users’ natural environments. Ana

SU(2) gauge theory with $N_f=24$ quarks at non-zero mass

Autor: Ahmed Salami, Jarno Rantaharju, Tobias Rindlisbacher, Kari Rummukainen, Kimmo Tuominen

We study SU(2) gauge field theory with $N_f=24$ quarks. The theory is asymptotically non-free and, at vanishing quark mass, governed by a Gaussian fixed point at long distances. On the other hand, at non-zero quark mass the quarks are expected to dec

The study of QFTs at finite density is hindered by the presence of the so-called sign problem. The action definition of such systems is, in fact, complex-valued making standard importance sampling Monte Carlo methods ineffective. In this work, we sha

Benchmark results in the 2D lattice Thirring model with a chemical potential

Autor: Venkitesh Ayyar, Shailesh Chandrasekharan, Jarno Rantaharju

Publikováno v: Physical Review

We study the two dimensional lattice Thirring model in the presence of a fermion chemical po- tential. Our model is asymptotically free, contains massive fermions that mimic a baryon and light bosons that mimic pions. Hence it is a useful toy model f
