Unitarity of Symplectic Fermion in -vacua with Negative Central Charge
Shinsei Ryu, Junggi Yoon
We study the two-dimensional free symplectic fermion with anti-periodic boundary condition. This model has negative norm states with naive inner product. This negative norm problem…
Tunneling between multiple histories as a solution to the information loss paradox
Pisin Chen, Misao Sasaki, Dong-han Yeom +1
The information loss paradox associated with black hole Hawking evaporation is an unresolved problem in modern theoretical physics. In a recent brief essay, we revisited the the ev…
Resolving information loss paradox with Euclidean path integral
Pisin Chen, Misao Sasaki, Dong-han Yeom +1
The information loss paradox remains unresolved ever since Hawking's seminal discovery of black hole evaporation. In this essay, we revisit the entanglement entropy via Euclidean p…
Color decorations of Jackiw-Teitelboim gravity
K. B. Alkalaev, Euihun Joung, Junggi Yoon
We introduce the colored version of Jackiw-Teitelboim (JT) gravity which is the two-dimensional dilaton gravity model with matrix-valued fields. It is straightforwardly formulated…
Schwarzian for colored Jackiw-Teitelboim gravity
K. B. Alkalaev, Euihun Joung, Junggi Yoon
We study the boundary effective action of the colored version of the Jackiw-Teitelboim (JT) gravity. We derive the boundary action, which is the color generalization of the Schwarz…
