Asymptotic Weyl Symmetry and Its Anomaly in a Curved Spacetime
Jeongwon Ho, O-Kab Kwon, Sang-A Park +1
We explore an unusual symmetry in a field theory on a specific (1+1)-dimensional curved spacetime, which has an interesting interpretation as an approximate asymptotic Weyl symmetr…

Quantum Inhomogeneous Field Theory: Unruh-Like Effects and Bubble Wall Friction
Jeongwon Ho, O-Kab Kwon, Sang-Heon Yi
In this paper, we study a free scalar field in a specific (1+1)-dimensional curved spacetime. By introducing an algebraic state that is locally Hadamard, we derive the renormalized…
