A Bayesian Approach to Comparing Cosmic Ray Energy Spectra
Bayesian Approach Cosmic Ray Energy Spectra
font style='font-size:12px;'>
2011/9/13
A common problem in ultra-high energy cosmic ray physics is the comparison of energy spectra. The question is whether the spectra from two experiments or two
regions of the sky agree within their sta...
Analytic approach to the study of the electric-magnetic asymmetry of the dimension 2 condensate
electric-magnetic asymmetry dimension 2 condensate
font style='font-size:12px;'>
2010/12/23
Recent work by Chernodub and Ilgenfritz has uncovered non-trivial temperature dependence in the electric-magnetic asymmetry in the dimension 2 condensate. This asymmetry measures the difference betwe...
Geometric approach to asymptotic expansion of Feynman integrals
Geometric asymptotic expansion Feynman integrals

2010/12/27
We present an algorithm that reveals relevant contributions in non-threshold-type asymptotic expansion of Feynman integrals about a small parameter. It is shown that the problem reduces to finding a c...
Boundary conditions in the Dirac approach to graphene devices
Boundary conditions Dirac approach graphene devices
font style='font-size:12px;'>
2010/12/27
We study a family of local boundary conditions for the Dirac problem corresponding to the continuum limit of graphene, both for nanoribbons and nanodots. We show that, among the members of such family...

Spin operator matrix elements in the quantum Ising chain: fermion approach
Spin operator matrix elements quantum Ising chain
font style='font-size:12px;'>
2010/12/27
Using some modification of the standard fermion technique we derive factorized formula for spin operator matrix elements (form-factors) between general eigenstates of the Hamiltonian of quantum Ising ...
Gauge invariant approach to low-spin anomalous conformal currents and shadow fields
low-spin anomalous conformal currents shadow fields
font style='font-size:12px;'>
2010/12/24
Conformal low-spin anomalous currents and shadow fields in flat space-time of dimension greater than or equal to four are studied. Gauge invariant formulation for such currents and shadow fields is de...
Cartesian approach for constrained mechanical systems
Cartesian approach constrained mechanical systems
font style='font-size:12px;'>
2010/11/19
In the history of mechanics, there have been two points of view for studying mechanical systems: Newtonian and Cartesian.
According the Descartes point of view, the motion of mechanical systems is ...
