Quasilocal energy and conserved charges derived from the gravitational action.
  • Brown, York
  • Physics, Medicine
    Physical review. D, Particles and fields
  • 29 September 1992
TLDR
For spherically symmetric spacetimes, it is shown that the quasilocal energy has the correct Newtonian limit, and includes a negative contribution due to gravitational binding.
Dust as a standard of space and time in canonical quantum gravity.
  • Brown, Kuchar
  • Physics, Medicine
    Physical review. D, Particles and fields
  • 1 September 1994
TLDR
The particles of dust introduce into space a privileged system of coordinates that allows the supermomentum constraint to be solved explicitly and yields a formally conserved inner product that can be written in terms of either the instantaneous state functionals or the solutions of constraints.
Scaling effective Lagrangians in a dense medium.
  • Brown, Rho
  • Physics, Medicine
    Physical review letters
  • 27 May 1991
TLDR
The approximate {ital in}{minus}{ital medium} scaling law is established, which has a highly nontrivial implication for nuclear processes at and above nuclear-matter density.
Charged black hole in a grand canonical ensemble.
Summing tree graphs at threshold.
  • Brown
  • Physics, Medicine
    Physical review. D, Particles and fields
  • 1 September 1992
TLDR
It is shown that the classical equation reduces to an easily solved ordinary differential equation for certain multiparticle threshold amplitudes and compute these amplitudes.
Temperature, energy, and heat capacity of asymptotically anti-de Sitter black holes.
  • Brown, Creighton, Mann
  • Physics, Medicine
    Physical review. D, Particles and fields
  • 3 May 1994
TLDR
The thermodynamic properties of black holes in (3+1)- and (2+1-dimensional Einstein gravity with a negative cosmological constant are investigated and it is shown that the chemical potential conjugate to angular momentum is equal to the proper angular velocity of the black hole with respect to observers who are at rest in the stationary time slices.
Fourfold anisotropy and structural behavior of epitaxial hcp Co/GaAs(001) thin films.
  • Gu, Gester, +7 authors Riedi
  • Physics, Medicine
    Physical review. B, Condensed matter
  • 15 November 1995
TLDR
In-plane magneto-optical Kerr-effect hysteresis loops and Brillouin light-scattering measurements show that the thinnest epitaxial hcp Co film (50 Angstrom) has a dominant fourfold anisotropy with easy axes along the in-plane [100] directions and that a uniaxial an isotropy becomes dominant with increasing film thickness.
Fractal boundaries for exit in Hamiltonian dynamics.
TLDR
It is found that the regions of initial-condition state space corresponding to the two exit modes are separated by a boundary that has both fractal and smooth (nonfractal) regions, for one example, and by a fractal boundary for the other example.
Microcanonical functional integral for the gravitational field.
  • Brown, York
  • Physics, Medicine
    Physical review. D, Particles and fields
  • 30 September 1992
TLDR
A general form of the first law of thermodynamics for stationary black holes is derived and the density of states is expressed as a real-time functional integral and then used to deduce Feynman's imaginary- time functional integral for the canonical partition function.
