Formation of the Hayward black hole from a collapsing shell
Hwajin Um, Wontae Kim
We consider a collapsing shell of matter to form the Hayward black hole and investigate semiclassically quantum radiation from the shell. Using the Israel's formulation, we obtain…

Unruh temperatures in circular and drifted Rindler motions
Yongwan Gim, Hwajin Um, Wontae Kim
We study the temperatures for the circular and drifted Rindler motions by employing the Unruh-DeWitt detector method. In the circular motion, the temperature is increasing along th…

Unruh effect of nonlocal field theories with a minimal length
Yongwan Gim, Hwajin Um, Wontae Kim
The nonlocal field theory commonly requires a minimal length, and so it appears to formulate the nonlocal theory in terms of the doubly special relativity which makes the speed of…
