Nematic ordering in the Heisenberg spin-glass system in three dimensions
Tunca, Egemen; Berker, A. Nihat (Amer Physical Soc, 2023)Nematic ordering, where the spins globally align along a spontaneously chosen axis irrespective of direction, occurs in spin-glass systems of classical Heisenberg spins in d = 3. In this system where the nearest-neighbor ... -
Renormalization-group theory of the Heisenberg model in d dimensions
Tunca, Egemen; Berker, A. Nihat (Elsevier, 2022)The classical Heisenberg model has been solved in spatial d dimensions, exactly in d = 1 and by the Migdal-Kadanoff approximation in d > 1, by using a Fourier-Legendre expansion. The phase transition temperatures, the ...
