Cluster Dynamics Stay Fast-Until Tricriticality
Minjun Jeon, Alexandros Vasilopoulos, Dong-Hee Kim +2
Cluster Monte Carlo algorithms are widely regarded as the most effective route to overcoming critical slowing down in lattice spin systems. Whether this acceleration persists in th…
Crossover and universality breaking in the dilute Baxter-Wu model
Dimitrios Mataragkas, Alexandros Vasilopoulos, Dong-Hee Kim +1
The critical behavior of the Baxter-Wu model belongs to the universality class of the four-state Potts model. While the introduction of annealed vacancies does not alter the critic…
Transfer-matrix approach to the Blume-Capel model on the triangular lattice
Dimitrios Mataragkas, Alexandros Vasilopoulos, Nikolaos G. Fytas +1
We investigate the spin- Blume-Capel model on an infinite strip of the triangular lattice using the transfer-matrix method combined with a sparse-matrix factorization technique.…
Tricriticality and finite-size scaling in the triangular Blume-Capel ferromagnet
Dimitrios Mataragkas, Alexandros Vasilopoulos, Nikolaos G. Fytas +1
We report on numerical simulations of the two-dimensional spin- Blume-Capel ferromagnet embedded in a triangular lattice. Utilizing a range of Monte Carlo and finite-size scalin…
Kinetic Roughening of Ion-Sputtered Pd(001) Surface: Beyond the Kuramoto-Sivashinsky Model
T. C. Kim, C. -M. Ghim, H. J. Kim +9
We investigate the kinetic roughening of Ar ion-sputtered Pd(001) surface both experimentally and theoretically. \textit{In situ} real-time x-ray reflectivity and \textit{in si…
