Quantum critical dynamics in two-dimensional transverse Ising model
Chisa Hotta, Tempei Yoshida, Kenji Harada
In the vicinity of the quantum critical point(QCP), thermodynamic properties diverge toward zero temperature governed by universal exponents. Although this fact is well known, how…
Emergent chiral symmetry in non-bipartite kagome and pyrochlore lattices with spin-orbit coupling
Hiroki Nakai, Masataka Kawano, Chisa Hotta
Chiral symmetry in energy bands appears as perfectly symmetric anti-bonding and bonding pairs of energy levels. It has only been observed in a few classes of models with a bipartit…
Phase diagram of the square lattice Hubbard model with Rashba-type antisymmetric spin-orbit coupling
Masataka Kawano, Chisa Hotta
We clarify the ground state phase diagram of the half-filled square-lattice Hubbard model with Rashba spin-orbit coupling (SOC) characterized by the spin-split energy bands due to…
Quantum mechanically driven structural-spin glass in two dimensions at finite temperature
Chisa Hotta, Kazumasa Ueda, Masatoshi Imada
In magnetic materials, spins sometimes freeze into spatially disordered glassy states. Glass forming liquids or structural glasses are found very often in three dimensions. However…
Purity of thermal mixed quantum states
Atsushi Iwaki, Chisa Hotta
We develop a formula to evaluate the purity of a series of thermal equilibrium states that can be calculated in numerical experiments without knowing the exact form of the quantum…
Supercooled Jahn-Teller Ice
Kota Mitsumoto, Chisa Hotta, Hajime Yoshino
When the spins on the frustrated pyrochlore lattice obey the celebrated 2--2- ice rule, they stay in a correlated disordered phase and break the third law of thermodynamic…
