Enhancement of photon emission rate near QCD critical point
Yukinao Akamatsu, Masayuki Asakawa, Masaru Hongo +2
We compute photon emission rate enhancement near the QCD critical point using an effective theory of dynamic critical phenomena and derive a universal photon spectrum. The emission…

Schwinger-Keldysh effective action for hydrodynamics with approximate symmetries
Masaru Hongo, Noriyuki Sogabe, Mikhail A. Stephanov +1
We study the hydrodynamic theories with approximate symmetries in the recently developed effective action approach on the Schwinger-Keldysh (SK) contour. We employ the method of sp…

Nonmonotonic specific entropy on the transition line near the QCD critical point
Maneesha Sushama Pradeep, Noriyuki Sogabe, Mikhail Stephanov +1
We investigate the effect of the quantum chromodynamics (QCD) critical point on the isentropic trajectories in the QCD phase diagram. We point out that the universality of the crit…
