Low-temperature thermodynamics of the two-leg ladder Ising model with trimer rungs: A mystery explained (2008.03753v1)
Published 9 Aug 2020 in cond-mat.stat-mech and cond-mat.str-el
Abstract: Recently, a surprising low-temperature behavior has been revealed in a two-leg ladder Ising model with trimer rungs (Weiguo Yin, arXiv:2006.08921). Motivated by these findings, we study this model from another perspective and demonstrate that the reported observations are related to a critical phenomenon in the standard Ising chain. We also discuss a related curiosity, namely, the emergence of a power-law behavior characterized by quasicritical exponents.
