The Fredenhagen-Marcu operator in the gauge-Higgs Z(2) LGT at finite temperature
B. Allés, B. Allés, O. Borisenko +2
We explore the possibility to use the Fredenhagen-Marcu operator as a candidate order parameter of the deconfinement phase transition in gauge matter systems at finite temperature.…
Confinement-Higgs and deconfinement-Higgs transitions in four-dimensional SU(2) LGT at finite temperature
B. Allés, O. Borisenko, A. Papa
We re-examine by numerical simulation the phase structure of the (3+1)-dimensional SU(2) lattice gauge theory (LGT) with gauge fields coupled to Higgs fields at finite temperature.…
Confinement-Higgs and deconfinement-Higgs transitions in three-dimensional LGT
B. Allés, O. Borisenko, A. Papa
We re-examine by numerical simulation the phase structure of the three-dimensional Abelian lattice gauge theory (LGT) with gauge fields coupled to -valued Higgs fields…
One-dimensional QCD at finite density and its 't Hooft-Veneziano limit
O. Borisenko, V. Chelnokov, S. Voloshyn +1
An exact solution of one-dimensional lattice gauge theory at finite temperature and non-zero chemical potential is reviewed for the gauge groups for all values…
