The effect of weekend curfews on epidemics: a Monte Carlo simulation
Kaygusuz, Hakan; Berker, A. Nihat (Tubitak Scientific & Technical Research Council Turkey, 2021)The ongoing COVID-19 pandemic is being responded with various methods, applying vaccines, experimental treatment options, total lockdowns or partial curfews. Weekend curfews are among the methods for reducing the number ... -
First-order to second-order phase transition changeover and latent heats of q-state Potts models in d=2,3 from a simple Migdal-Kadanoff adaptation
Devre, H. Yagiz; Berker, A. Nihat (Amer Physical Soc, 2022)The changeover from first-order to second-order phase transitions in q-state Potts models is obtained at q(c) = 2 in spatial dimension d = 3 and essentially at q(c) = 4 in d = 2, using a physically intuited simple adaptation ... -
Lower critical dimension of the random-field XY model and the zero-temperature critical line
Akin, Kutay; Berker, A. Nihat (Amer Physical Soc, 2022)The random-field XY model is studied in spatial dimensions d = 3 and 4, and in between, as the limit q -> infinity of the q-state clock models, by the exact renormalization-group solution of the hierarchical lattice or, ... -
Merged Potts-clock model: Algebraic and conventional multistructured multicritical orderings in two and three dimensions
Artun, E. Can; Berker, A. Nihat (Amer Physical Soc, 2023)A spin system is studied with simultaneous permutation-symmetric Potts and spin-rotation-symmetric clock interactions in spatial dimensions d = 2 and 3. The global phase diagram is calculated from the renormalization-group ... -
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 ... -
Spin-s spin-glass phases in the d=3 Ising model
Artun, E. Can; Berker, A. Nihat (Amer Physical Soc, 2021)All higher-spin (s >= 1/2) Ising spin glasses are studied by renormalization-group theory in spatial dimension d = 3, exactly on a d = 3 hierarchical model and, simultaneously, by the Migdal-Kadanoff approximation on the ...
