Statistically induced Phase Transitions: Turning Bosons smoothly via Anyons into Fermions
Phase Transitions Fermions
font style='font-size:12px;'>
2010/10/27
Anyons { particles carrying fractional statistics that interpolate between bosons and fermions { have been conjectured to exist in low dimensional systems. In the context of the fractional quantum Hal...
Noisy Random Boolean Formulae - a Statistical Physics Perspective
noisy logical gates Statistical Physics
font style='font-size:12px;'>
2010/4/6
Typical properties of computing circuits composed of noisy logical gates are studied using the statistical physics methodology. A growth model that gives rise to typical random Boolean functions is ma...
Micro-Macro Relation of Production - The Double Scaling Law for Statistical Physics of Economy
Micro-Macro Scaling Law Production Statistical Physics
font style='font-size:12px;'>
2010/4/27
We show that an economic system populated by multiple agents generates an equilibrium distribution in the form of multiple scaling laws of conditional PDFs, which are sufficient for characterizing the...
Quantum entanglement and entropy in particle creation
Quantum entanglement particle creation entropy

2010/3/18
We investigate the basic theoretical issues in the quantum entanglement of particle pairs created from the vacuum in a time-dependent background field or spacetime. Similar to entropy generation from ...
Towards Tests of Alternative Theories of Gravity with LISA
Gravitational Wave Astronomy Extreme-Mass-Ratio Inspirals
font style='font-size:12px;'>
2010/3/18
The inspiral of stellar compact objects into massive black holes, usually known as extreme-mass-ratio inspirals (EMRIs), is one of the most important sources of gravitational-waves for the future Lase...
Late-time tails of a self-gravitating Einstein-Skyrme model
Late-time tails self-gravitating Einstein-Skyrme model
font style='font-size:12px;'>
2010/3/18
We consider the long-time behaviour of spherically symmetric solutions in the Einstein-Skyrme model. Using nonlinear perturbation analysis we obtain the leading order estimation of the tail in the top...
F-theory and the LHC: Stau Search
F-theory soft supersymmetry
font style='font-size:12px;'>
2010/3/15
F-theory GUT models favor a relatively narrow range of soft supersymmetry breaking parameters in the MSSM Lagrangian. This leads to the specific predictions that a 10-100 MeV mass gravitino is the LSP...
Consistency of Equations for the Single Scalar Field Case in Second-order Gauge-invariant Cosmological Perturbation Theory
Single Scalar Field Case Cosmological Perturbation Theory
font style='font-size:12px;'>
2010/3/18
We derived the second-order perturbations of the Einstein equations and the Klein-Gordon equation for a generic situation in terms of gauge-invariant variables. The consistency of all the equations is...
Consistent Histories in Quantum Cosmology
Quantum Cosmology quantum states
font style='font-size:12px;'>
2010/3/18
We illustrate the crucial role played by decoherence (consistency of quantum histories) in extracting consistent quantum probabilities for alternative histories in quantum cosmology. Specifically, wit...
Advances in Simulations of Generic Black-Hole Binaries
Black-Hole Binaries hybrid post-Newtonian
font style='font-size:12px;'>
2010/3/18
We review some of the recent dramatic developments in the fully nonlinear simulation of generic, highly-precessing, black-hole binaries, and introduce a new approach for generating hybrid post-Newtoni...
Wormholes or Gravastars?
Wormholes Gravastars Zero Point Energy
font style='font-size:12px;'>
2010/3/18
The one loop effective action in a Schwarzschild background is here used to compute the Zero Point Energy (ZPE) which is compared to the same one generated by a gravastar. We find that only when we se...
Notes Concerning "On the Origin of Gravity and the Laws of Newton" by E. Verlinde
structure of spacetime partition function phase transition
font style='font-size:12px;'>
2010/3/18
We point out that certain equations which, in a very recent paper written by E. Verlinde, are postulated as a starting point for a thermodynamical derivation of classical gravity, are actually consequ...
