The Widom line in the Ising model on a decorated bilayer lattice
Joseph Chapman, Justas Gidziunas, Bruno Tomasello +1
There has been much recent interest devoted to a class of frustrated one-dimensional statistical mechanics lattice models which exhibit sharp thermodynamics. In this work, we study…
Bifurcation in correlation length of the Ising model on a "Toblerone" lattice
Joseph Chapman, Bruno Tomasello, Sam T. Carr
The classical Ising chain is the paradigm for the non-existence of phase transitions in 1D systems and was solved by Ernst Ising one hundred years ago. More recently, a decorated t…
Quantum discord in a spin system with symmetry breaking
Bruno Tomasello, Davide Rossini, Alioscia Hamma +1
We analyze the quantum discord Q throughout the low-temperature phase diagram of the quantum XY model in transverse field. We first focus on the T=0 order-disorder quantum phase tr…
