Phase diagram near the quantum critical point in Schwinger model at : analogy with quantum Ising chain
Hiroki Ohata
The Schwinger model, one-dimensional quantum electrodynamics, has CP symmetry at due to the topological nature of the term. At zero temperature, it is known that as incr…

A new perspective on thermal transition in QCD
Masanori Hanada, Hiroki Ohata, Hidehiko Shimada +1
Motivated by the picture of partial deconfinement developed in recent years for large- gauge theories, we propose a new way of analyzing and understanding thermal phase transiti…

Monte Carlo study of Schwinger model without the sign problem
Hiroki Ohata
Monte Carlo study of the Schwinger model (quantum electrodynamics in one spatial dimension) with a topological term is very difficult due to the sign problem in the conventiona…
