Dynamical Singularities of Glassy Systems in a Quantum Quench
Tomoyuki Obuchi, Kazutaka Takahashi
We present a prototype of behavior of glassy systems driven by quantum dynamics in a quenching protocol by analyzing the random energy model in a transverse field. We calculate sev…

Spin and chiral orderings of the antiferromagnetic XY model on the triangular lattice and their critical properties
Tomoyuki Obuchi, Hikaru Kawamura
We study the antiferromagnetic {\it XY} model on a triangular lattice by extensive Monte Carlo simulations, focusing on its ordering and critical properties. Our result clearly sho…

Replica symmetry breaking, complexity and spin representation in the generalized random energy model
Tomoyuki Obuchi, Kazutaka Takahashi, Koujin Takeda
We study the random energy model with a hierarchical structure known as the generalized random energy model (GREM). In contrast to the original analysis by the microcanonical ensem…
