Polarization Jumps across Topological Phase Transitions in Two-dimensional Systems
Hiroki Yoshida, Tiantian Zhang, Shuichi Murakami
In topological phase transitions involving a change in topological invariants such as the Chern number and the topological invariant, the gap closes, and the electri…
Complex Langevin Method on Rotating Matrix Quantum Mechanics at Thermal Equilibrium
Takehiro Azuma, Takeshi Morita, Hiroki Yoshida
Rotating systems in thermal equilibrium are ubiquitous in our world. In the context of high energy physics, rotations would affect the phase structure of QCD. However, the standard…
Polarization jumps by breaking symmetries of two-dimensional Weyl semimetals
Hiroki Yoshida, Tiantian Zhang, Shuichi Murakami
The electric polarization as a bulk quantity is described by the modern theory of polarization in insulating systems and cannot be defined in conducting systems. Upon a gradual cha…
Dynamical Lee-Yang zeros for continuous-time and discrete-time stochastic processes
Hiroki Yoshida, Kazutaka Takahashi
We describe classical stochastic processes by using dynamical Lee-Yang zeros. The system is in contact with external leads and the time evolution is described by the two-state clas…
Critical Dimension and Negative Specific Heat in One-dimensional Large-N Reduced Models
Takeshi Morita, Hiroki Yoshida
We investigate critical phenomena of the Yang-Mills (YM) type one-dimensional matrix model that is a large- reduction (or dimensional reduction) of the dimensional …
