Hamiltonian dynamics for Einstein's action in G$\rightarrow$0 limit
Hamiltonian dynamics Einstein's action Mathematical Physics
2011/9/15
Abstract: The Hamiltonian analysis for the Einstein's action in $ G\to 0 $ limit is performed. Considering the original configuration space without involve the usual $ADM$ variables we show that the v...
Coupling of gravity to matter, spectral action and cosmic topology
Coupling of gravity spectral action cosmic topology
2011/7/26
Abstract: We consider a model of modified gravity based on the spectral action functional, for a cosmic topology given by a spherical space form, and the associated slow-roll inflation scenario. We co...
A ten-dimensional action for non-geometric fluxes
ten-dimensional action non-geometric fluxes High Energy Physics - Theory
2011/7/28
Abstract: The NSNS Lagrangian of ten-dimensional supergravity is rewritten via a change of field variables inspired by Generalized Complex Geometry. We obtain a new metric and dilaton, together with a...

Action-angle duality between the C(n)-type hyperbolic Sutherland and the rational Ruijsenaars-Schneider-van Diejen models
Action-angle duality the C(n)-type hyperbolic Sutherland the rational Ruijsenaars-Schneider-van Diejen models
2011/7/26
Abstract: In a symplectic reduction framework we construct action-angle systems of canonical coordinates for both the hyperbolic Sutherland and the rational Ruijsenaars-Schneider-van Diejen integrable...
The Random Discrete Action for 2-Dimensional Spacetime
The Random Discrete Action 2-Dimensional Spacetime
2010/12/27
A one-parameter family of random variables, called the Discrete Action, is defined for a 2-dimensional Lorentzian spacetime of finite volume. The single parameter is a discreteness scale. The expecta...
FV-type action for AdS(5) mixed-symmetry fields
FV-type action AdS(5) mixed-symmetry fields
2010/12/21
We formulate Fradkin-Vasiliev type theory of massless higher spin fields in AdS5.The corresponding action functional describes cubic order approximation to gravita-tional interactions of bosonic mixed...
Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action
Charmonium-nucleon interaction lattice QCD relativistic heavy quark action
2011/1/13
Detailed information of the low-energy interaction between the charmonia (hc and J=y) and the
nucleon is indispensable for exploring the formation of charmonium bound to nuclei. In order
to investig...
Cosmological Models with Fractional Derivatives and Fractional Action Functional
Fractional Derivative and Integral Cosmology
2010/12/20
Cosmological models of a scalar field with dynamical equations containing fractional derivatives or derived from the Einstein-Hilbert action of fractional order, are constructed. A number of exact sol...
There is no spooky action-at-a-distance in quantum correlations: Resolution of the EPR nonlocality puzzle
spooky action-at-a-distance quantum correlations: Resolution EPR nonlocality puzzle
2010/10/18
The long-standing puzzle of the nonlocal Einstein-Podolsky-Rosen correlations is resolved. The correct quantum mechanical correlations arise for the case of entangled particles when strict locality is...
