Real critical exponents from the $ε$ -expansion in an interacting $U (1)$ model with non-Hermitian $Z_{4}$ anisotropy

Eduard Naichuk, Jeroen van den Brink, Flavio S. Nogueira

In quantum optics and condensed matter physics non-Hermitian phenomena are often studied under the assumption of an open physical system. However, there are examples of intrinsical…

Walking behavior induced by $P T$ symmetry breaking in a non-Hermitian $XY$ model with clock anisotropy

Eduard Naichuk, Jeroen van den Brink, Flavio S. Nogueira

A quantum system governed by a non-Hermitian Hamiltonian may exhibit zero temperature phase transitions that are driven by interactions, just as its Hermitian counterpart, raising…
