Spacetime Emergence and General Covariance Transmutation
Chiu Man Ho, Thomas W. Kephart, Djordje Minic +1
Spacetime emergence refers to the notion that classical spacetime "emerges" as an approximate macroscopic entity from a non-spatio-temporal structure present in a more complete the…
Projective Geometry and -Symmetric Dirac Hamiltonian
Y. Jack Ng, H. van Dam
The -dimensional (generalized) Dirac equation is shown to have the same form as the equation expressing the condition that a given point lies on a given line in 3-dimensio…
Replacing Anthropy with entropy: Does it work?
Irit Maor, Thomas W. Kephart, Lawrence M. Krauss +2
Probably not, because there are lots of manifestly unanthropic ways of producing entropy. We demonstrate that the Causal Entropic Principle (CEP), as a replacement for the anthropi…
The Partition Function and Level Density for Yang-Mills-Higgs Quantum Mechanics
S. G. Matinyan, Y. Jack Ng
We calculate the partition function and the asymptotic integrated level density for Yang-Mills-Higgs Quantum Mechanics for two and three dimensions (). Due…
A geometrical derivation of the Dirac equation
Y. Jack Ng, H. van Dam
We give a geometrical derivation of the Dirac equation by considering a spin-1/2 particle travelling with the speed of light in a cubic spacetime lattice. The mass of the particle…
The effective potential of composite fields in weakly coupled QED in a uniform external magnetic field
D. -S. Lee, P. N. McGraw, Y. J. Ng +1
The effective potential for the composite fields responsible for chiral symmetry breaking in weakly coupled QED in a magnetic field is derived. The global minimum of the effective…
Magnetic catalysis of chiral symmetry breaking and the Pauli problem
Y. Jack Ng
The non-perturbative Schwinger-Dyson equation is used to show that chiral symmetry is dynamically broken in QED at weak gauge couplings when an external uniform magnetic field is p…
Chiral symmetry breaking in a uniform external magnetic field II. Symmetry restoration at high temperatures and chemical potentials
D. -S. Lee, C. N. Leung, Y. J. Ng
Chiral symmetry is dynamically broken in quenched, ladder QED at weak gauge couplings when an external magnetic field is present. In this paper, we show that chiral symmetry is res…
Observability of the Bulk Casimir Effect: Can the Dynamical Casimir Effect be Relevant to Sonoluminescence?
Kimball A. Milton, Y. Jack Ng
The experimental observation of intense light emission by acoustically driven, periodically collapsing bubbles of air in water (sonoluminescence) has yet to receive an adequate exp…
Chiral Symmetry Breaking in a Uniform External Magnetic Field
D. -S. Lee, C. N. Leung, Y. J. Ng
Using the nonperturbative Schwinger-Dyson equation, we show that chiral symmetry is dynamically broken in QED at weak couplings when an external magnetic field is present, and that…
Chiral Symmetry Breaking by a Magnetic Field in Weak-coupling QED
C. N. Leung, Y. J. Ng, A. W. Ackley
Using the nonperturbative Schwinger-Dyson equation, we show that chiral symmetry in weak-coupling massless QED is dynamically broken by a constant but arbitrarily strong external m…
A Generalization of Quantum Statistics
Wei Chen, Jack Y. Ng, Hendrik van Dam
We propose a new fractional statistics for arbitrary dimensions, based on an extension of Pauli's exclusion principle, to allow for finite multi-occupancies of a single quantum sta…
