High energy physics signatures from inflation and conformal symmetry of de Sitter [PDF]

, 2015
During inflation, the geometry of spacetime is described by a (quasi‐)de Sitter phase. Inflationary observables are determined by the underlying (softly broken) de Sitter isometry group SO(1,4) which acts like a conformal group on R3 : when the ...

Gravitational Wave Implications for the Parity Symmetry of Gravity in the High Energy Region

, 2021
Einstein's general relativity, as the most successful theory of gravity, is one of the cornerstones of modern physics. However, the experimental tests for gravity in the high energy region are limited. The emerging gravitational-wave astronomy has opened

Zettawatt-Exawatt Lasers and Their Applications in Ultrastrong-Field Physics: High Energy Front [PDF]

, 2001
Since its birth, the laser has been extraordinarily effective in the study and applications of laser-matter interaction at the atomic and molecular level and in the nonlinear optics of the bound electron.

Non-equilibrium field theory [PDF]

, 2000
I discuss various topics in relativistic non-equilibrium field theory related to high energy physics and cosmology. I focus on non-perturbative problems and how they can be treated on the lattice.Comment: Plenary talk given at the 18th International ...

The Standard Model of Electroweak Interactions [PDF]

, 2007
Gauge invariance is a powerful tool to determine the dynamics of the electroweak and strong forces. The particle content, structure and symmetries of the Standard Model Lagrangian are discussed.

Decoupling in an expanding universe: boundary RG-flow affects initial conditions for inflation

, 2004
We study decoupling in FRW spacetimes, emphasizing a Lagrangian description throughout. To account for the vacuum choice ambiguity in cosmological settings, we introduce an arbitrary boundary action representing the initial conditions.

Trace Anomaly and Quantization of Maxwell's Theory on Non-Commutative Spaces

, 2002
The canonical and symmetrical energy-momentum tensors and their non-zero traces in Maxwell's theory on non-commutative spaces have been found. Dirac's quantization of the theory under consideration has been performed.
