Notes on the Schwinger model: regularization and gauge invariance
the Schwinger model regularization and gauge invariance Mathematical Physics
2012/6/21
The point-splitting computation of the gauge invariant Hamiltonian for the Schwinger model on the circle in a positive energy representation is presented.
Notes on dark energy interacting with dark matter and unparticle in loop quantum cosmology
Notes dark energy dark matter unparticle loop quantum cosmology
2011/8/3
Abstract: We investigate the behavior of dark energy interacting with dark matter and unparticle in the framework of loop quantum cosmology. In four toy models, we study the interaction between the co...

Notes on Ghost Dark Energy
Notes Ghost Dark Energy
2010/12/27
We study a phenomenological dark energy model which is rooted in the Veneziano ghost of QCD. In this dark energy model, the energy density of dark energy is proportional to Hubble parameter and the pr...

Notes Concerning "On the Origin of Gravity and the Laws of Newton" by E. Verlinde
structure of spacetime partition function phase transition
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...
Optical-Wavelength Paramagnetic Phaser (Lecture Notes). Section 3.1. Nonlinear Balance Equations of Motion
Optical-Wavelength Paramagnetic Phaser Nonlinear Balance Equations class-B lasers
2010/4/1
In this work I present a detailed description of the simplest nonlinear model for an optical wavelength paramagnetic phaser, which is an acoustic analog of the class-B lasers. Despite of its simplicit...
