Effective field theory for hydrodynamics: Wess-Zumino term and anomalies in two spacetime dimensions
Effective field theory hydrodynamics:anomalies spacetime dimensions
2011/10/14
We develop the formalism that incorporates quantum anomalies in the effective field theory of non-dissipative fluids. We consider the effect of adding a Wess-Zumino-like term to the low-energy effecti...
Homochirality through Photon-Induced Melting of RNA/DNA: the Thermodynamic Dissipation Theory of the Origin of Life
Homochirality Photon-Induced Melting RNA/DNA
2011/1/13
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication...
Theory of Feedback in Clusters and Molecular Cloud Turbulence
Feedback in Clusters Molecular Cloud Turbulence
2011/1/11
I review recent numerical and analytical work on the feedback from both low- and high-mass cluster stars into their gasoeus environment. The main conclusions are that i) outflow driving appears capabl...
Applications of the IGIMF-theory to the astrophysics of galaxies
Applications astrophysics of galaxies
2010/11/12
The functional form of the galaxy-wide stellar initial mass function is of fundamental importance for understanding galaxies. So far this stellar initial mass function has been assumed to be identical...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
Unified cosmic history theory Lorentz non-invariant models
2010/11/16
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structure and cosm...
Quantifying the Imprecision of Accretion Theory and Implications for Multi-Epoch Observations of Protoplanetary Discs
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP) High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
If accretion disc emission results from turbulent dissipation, then axisymmetric accretion theory must be used as a mean field theory: turbulent flows are at most axisymmetric only when suitably avera...
Quantum theory, gravity, and the standard model of particle physics : using the hints of today to build the final theory of tomorrow
Quantum theory gravity particle physics
2010/3/19
When a mountaineer is ascending one of the great peaks of the Himalayas she knows that an entirely new vista awaits her at the top, whose ramifications will be known only after she gets there. Her imm...
Local causal structures, Hadamard states and the principle of local covariance in quantum field theory
quantum field theory local covariance
2010/3/18
In the framework of the algebraic formulation, we discuss and analyse some new features of the local structure of a real scalar quantum field theory in a strongly causal spacetime. In particular we us...
Noncommutative gauge theory using covariant star product defined between Lie valued differential forms
covariant star product differential forms symplectic manifold
2010/3/18
We develop an internal gauge theory using a covariant star product. The space-time is a symplectic manifold endowed only with torsion but no curvature. It is shown that, in order to assure the restric...
Singularities in Horava-Lifshitz theory
Horava-Lifshitz Lu-Mei-Pope Schwarzschild solutions
2010/3/18
Singularities in $(3+1)$-dimensional Horava-Lifshitz (HL) theory of gravity are studied. These singularities can be divided into scalar, non-scalar curvature, and coordinate singularities. Because of ...
