  12. 19. Quantum tunneling, decoherence and the beginning of the Universe from Lefschetz thimble real-time simulations
    Prof. Jun Nishimura
    11/12/2024, 17:25

    Monte　Carlo simulations of quantum time-evolution based on the real-
    time path integral have been thought to be extremely difficult since it involves a
    phase factor exp(iS) in the integrand, which causes a severe sign
    problem. We apply the Lefschetz thimble method with various new
    techniques to such systems. In this talk, I would like to discuss a new
    understanding of quantum tunneling...

  28. 38. Revisiting Hawking Radiation via Generalized Uncertainty Principle
    Mr Tin-Long Chau
    12/12/2024, 17:40

    The generalized uncertainty relation is expected to be an essential element in a theory of quantum gravity. We examine its effect on the Hawking radiation of a Schwarzschild black hole formed from collapse by incorporating a minimal uncertainty length scale into the radial coordinate of the background. This is implemented in both the ingoing Vaidya coordinates and a family of freely falling...

  30. 39. UV Origin of Late-time Hawking Radiation
    Mr Cheng-Tsung WANG
    12/12/2024, 18:05

    We reexamined the connection between the Hawking radiation of a Schwarzschild black hole formed from collapse and ultraviolet(UV) physics with the local Lorentz symmetry violation or the existence of a minimal length. Significant modifications are reported after the scrambling time in both cases, which reflects the UV sensitivity of Hawking radiation. Depending on the physics at the...
