Computer-Generated Holographic Optical Tweezer Arrays
Eric R. Dufresne, Gabriel C. Spalding, Matthew T. Dearing +2
Holographic techniques significantly extend the capabilities of laser tweezing, making possible extended trapping patterns for manipulating large numbers of particles and volumes o…
Extremal Black holes and the limits of the third law
Stefano Liberati, Tony Rothman, Sebastiano Sonego
Recent results of quantum field theory on a curved spacetime suggest that extremal black holes are not thermal objects and that the notion of zero temperature is ill-defined for th…
Holonomy in the Schwarzschild-Droste Geometry
Tony Rothman, George F. R. Ellis, Jeff Murugan
Parallel transport of vectors in curved spacetimes generally results in a deficit angle between the directions of the initial and final vectors. We examine such holonomy in the Sch…
Nonthermal nature of extremal Kerr black holes
Tony Rothman
Liberati, Rothman and Sonego have recently showed that objects collapsing into extremal Reissner-Nordstrom black holes do not behave as thermal objects at any time in their history…
Hidden Variables or Positive Probabilities?
Tony Rothman, E. C. G. Sudarshan
Despite claims that Bell's inequalities are based on the Einstein locality condition, or equivalent, all derivations make an identical mathematical assumption: that local hidden-va…
Nonthermal nature of incipient extremal black holes
S. Liberati, T. Rothman, S. Sonego
We examine particle production from spherical bodies collapsing into extremal Reissner-Nordström black holes. Kruskal coordinates become ill-defined in the extremal case, but we ar…
