DOI: 10.1088/1361-6382/ac1fd2

Abstract: We study the evaporation of a four-dimensional spherically symmetric black hole formed in a gravitational collapse. We analyze the back-reaction of a massless quantum scalar field conformally coupled to the scalar curvature by means of… read more here.

DOI: 10.1103/physrevc.109.055203

Abstract: We investigate theoretically a nonrelativistic trace anomaly and its impact on the low-temperature equation of state in spatially one-dimensional three-component fermionic systems with a three-body interaction, which exhibit a nontrivial three-body crossover from a bound trimer… read more here.

DOI: 10.1103/physrevd.104.056008

Abstract: We compute trace anomaly contribution to hydrogen atom mass, which turns out to be related to the part of the Lamb shift. This finding might shed new light on our understandings of the mass structure… read more here.

DOI: 10.1103/physrevd.99.105007

Abstract: The effective average action is a form of effective action which depends on a cutoff scale suppressing the contribution of low momentum modes in the functional integral. It reduces to the ordinary effective action when… read more here.
