  • Are Black Holes Springy? 
    Good, Michael R.R.; Ong, Yen Chin (2014)
    A (3+1)-dimensional asymptotically at Kerr black hole angular speed + can be used to de ne an e ective spring constant, k = m2 +. Its maximum value is the Schwarzschild surface gravity, k = , which rapidly weakens as ...
  • Black Hole - Moving Mirror I: An Exact Correspondence 
    Anderson, Paul R.; Good, Michael R.R.; Evans, Charles R. (2015)
    An exact correspondence is shown between a new moving mirror trajectory in (1+1)D and a spacetime in (1+1)D in which a black hole forms from the collapse of a null shell. It is shown that the Bogolubov coe cients between ...
  • Black Hole - Moving Mirror II: Particle Creation 
    Good, Michael R.R.; Anderson, Paul R.; Evans, Charles R. (2016)
    There is an exact correspondence between the simplest solution to Einstein's equa- tions describing the formation of a black hole and a particular moving mirror tra- jectory. In both cases the Bogolubov coe cients in 1+1 ...
  • Extremal Black Hole in a Nonlinear Newtonian Theory of Gravity 
    Good, Michael R.R. (2013-01-22)
    This work investigates an upper-limit of charge for a black hole in a nonlinear Newtonian theory of gravity. The charge is accumulated via protons fired isotropically at the black hole. This theoretical study of gravity ...
  • Geometric creation of quantum vorticity 
    Good, Michael R.R.; Xiong, Chi; Chua, Alvin J.K.; Huang, Kerson (2015)
    We consider superfluidity and quantum vorticity in rotating spacetimes. The system is described by a complex scalar satisfying a nonlinear Klein-Gordon equation. Rotation terms are identified and found to lead to the ...
  • On horizonless temperature with an accelerating mirror 
    Good, Michael R.R.; Yelshibekova, Khalykbek; Chin Ong, Yen (ArXiv, 2017-03-03)
    A new solution of a unitary moving mirror is found to produce nite energy and emit thermal radiation despite the absence of an acceleration horizon. In the limit that the mirror approaches the speed of light, the model ...
  • On Spin-Statistics and Bogoliubov Transformations in Flat Spacetime With Acceleration Conditions 
    Good, Michael R.R. (2013-02-01)
    A single real scalar field of spin zero obeying the Klein-Gordon equation in flat spacetime under external conditions is considered in the context of the spin-statistics connection. An imposed accelerated boundary on the ...
  • Relativistic superfluidity and vorticity from the nonlinear Klein-Gordon equation 
    Good, Michael R.R.; Xiong, Chi; Guo, Yulong; Liu, Xiaopei; Huang, Kerson (2014)
    We investigate superfluidity, and the mechanism for creation of quantized vortices, in the relativistic regime.The general framework is a nonlinear Klein-Gordon equation in curved spacetime for a complex scalar field, whose ...
  • Signatures of Energy Flux in Particle Production: A Black Hole Birth Cry and Death Gasp 
    Good, Michael R.R.; Ong, Yen Chin (2015)
    It is recently argued that if the Hawking radiation process is unitary, then a black hole's mass cannot be monotonically decreasing. We examine the time dependent particle count and negative energy flux in the non-trivial ...
  • Time Dependence of Particle Creation from Accelerating Mirrors 
    Good, Michael R.R.; Anderson, Paul R.; Evans, Charles R. (2013-03-28)
    Particle production due to a quantized, massless, minimally coupled scalar eld in two-dimensional at spacetime with an accelerating mirror is investigated, with a focus on the time dependence of the process. We analyze ...
