I will introduce the thermodynamic phase diagram of a multilayered triangular lattice Ising model (MLTIM) with a finite number of vertically stacked layers. We will see that above a critical number of layers, there is a low temperature reentrance of one or two Berezinskii-Kosterlitz-Thouless (BKT) transitions, which results in an extended pseudo-critical… CONTINUE READING
