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…

The quasilocal energy and thermodynamic first law in accelerating AdS black holes
Wontae Kim, Mungon Nam, Sang-Heon Yi
We scrutinize the conserved energy of an accelerating AdS black hole by employing the off-shell quasilocal formalism, which amalgamates the ADT formalism with the covariant phase s…

Janus Deformation of de Sitter Space and Transitions in Gravitational Algebras
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We consider a time-dependent deformation of pure de Sitter (dS) space in dS gravity coupled to a massless scalar field. It is the dS counterpart of the AdS Janus…
