Partner formula for an arbitrary moving mirror in dimensions
Takeshi Tomitsuka, Koji Yamaguchi, Masahiro Hotta
In the information loss problem in black hole evaporation, investigation of the purification partner of a Hawking particle is crucial. It is a well-known fact that 3+1 dimensional…
Spatially Overlapped Partners in Quantum Field Theory
Jose Trevison, Koji Yamaguchi, Masahiro Hotta
In quantum field theory particles are physically defined as what Unruh-DeWitt particle detectors observe. By detecting a particle mode , a reduced density operator for a quantum…
Soft-Hair-Enhanced Entanglement Beyond Page Curves in a Black-hole Evaporation Qubit Model
Masahiro Hotta, Yasusada Nambu, Koji Yamaguchi
We propose a model with multiple qubits that reproduces the thermal properties of 4-dimensional (4-dim) Schwarzschild black holes (BHs) by simultaneously taking account of the emis…
Gravitational Memory Charges of Supertranslation and Superrotation on Rindler Horizons
Masahiro Hotta, Jose Trevison, Koji Yamaguchi
In a Rindler-type coordinate system spanned in a region outside of a black hole horizon, we have nonvanishing classical holographic charges as soft hairs on the horizon for station…
