Charged Particle and Strong Cosmic Censorship in Reissner-Nordström-de Sitter Black Holes
Yongwan Gim, Bogeun Gwak
We investigate the instability of the unstable circular orbit of a charged null particle to test the strong cosmic censorship conjecture in Nariai-type near-extremal Reissner--Nord…
The role of the cosmological constant as a pressure in the (2+1)-dimensional black string
Yongwan Gim, Wontae Kim
It has been claimed that the cosmological constant in AdS black holes such as the BTZ black hole plays the role of the thermodynamic variable of a pressure in the thermodynamic fir…
A Survey on Nonconvex Regularization Based Sparse and Low-Rank Recovery in Signal Processing, Statistics, and Machine Learning
Fei Wen, Lei Chu, Peilin Liu +1
In the past decade, sparse and low-rank recovery have drawn much attention in many areas such as signal/image processing, statistics, bioinformatics and machine learning. To achiev…
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…
Validity of black hole complementarity in the BTZ black hole
Yongwan Gim, Wontae Kim
Based on the gedanken experiment for black hole complementarity in the Schwarzschild black hole, we calculate the energy required to duplicate information in the BTZ black hole und…
