Partial deconfinement in QCD at $N = 3$ and $N = \infty$

Masanori Hanada, Hiroki Ohata, Hidehiko Shimada +1

We describe how the general mechanism of partial deconfinement applies to large- $N$ QCD and the partially-deconfined phase inevitably appears between completely-confined and comple…

Phase diagram near the quantum critical point in Schwinger model at $θ = π$ : analogy with quantum Ising chain

Hiroki Ohata

The Schwinger model, one-dimensional quantum electrodynamics, has CP symmetry at $θ = π$ due to the topological nature of the $θ$ term. At zero temperature, it is known that as incr…
