Qubit Heating Near a Hotspot
G. Kaplanek, C. P. Burgess, R. Holman
Effective theories describing black hole exteriors contain many open-system features due to the large number of gapless degrees of freedom that lie beyond reach across the horizon.…
Influence Through Mixing: Hotspots as Benchmarks for Basic Black-Hole Behaviour
G. Kaplanek, C. P. Burgess, R. Holman
Effective theories are being developed for fields outside black holes, often with an unusual open-system feel due to the influence of large number of degrees of freedom that lie ou…
Qubits on the Horizon: Decoherence and Thermalization near Black Holes
Greg Kaplanek, C. P. Burgess
We examine the late-time evolution of a qubit (or Unruh-De Witt detector) that hovers very near to the event horizon of a Schwarzschild black hole, while interacting with a free qu…
Hot Cosmic Qubits: Late-Time de Sitter Evolution and Critical Slowing Down
Greg Kaplanek, C. P. Burgess
Temporal evolution of a comoving qubit coupled to a scalar field in de Sitter space is studied with an emphasis on reliable extraction of late-time behaviour. The phenomenon of cri…
Hot Accelerated Qubits: Decoherence, Thermalization, Secular Growth and Reliable Late-time Predictions
Greg Kaplanek, C. P. Burgess
We compute how an accelerating qubit coupled to a scalar field - i.e. an Unruh-DeWitt detector - evolves in flat space, with an emphasis on its late-time behaviour. When calculable…
Failure of Perturbation Theory Near Horizons: the Rindler Example
C. P. Burgess, Joshua Hainge, Greg Kaplanek +1
Persistent puzzles to do with information loss for black holes have stimulated critical reassessment of the domain of validity of semiclassical EFT reasoning in curved spacetimes,…
