Observational Constraints on Interacting Model of New Agegraphic Dark Energy and Alleviation of Cosmic Age Problem
Observational Constraints on Interacting Model Agegraphic Dark Energy
2010/12/27
Many dark energy models fail to pass the cosmic age test via the old quasar APM 08279+5255 at redshift $z=3.91$, even the $\Lambda$CDM model and the holographic dark energy model are not exception. I...
Phase diagram and critical endpoint for strongly-interacting quarks
Phase diagram critical endpoint strongly-interacting quarks
2011/1/7
We introduce a method based on the chiral susceptibility, which enables one to draw a phase diagram in the chemical-potential/temperature plane for strongly-interacting quarks whose interactions are d...
Infrared behavior in systems with a broken continuous symmetry: classical O(N) model vs interacting bosons
Infrared behavior in systems broken continuous symmetry interacting bosons
2010/11/23
In systems with a spontaneously broken continuous symmetry, the perturbative loop expansion
is plagued with infrared divergences due to the coupling between transverse and longitudinal fluctuations.A...

Higher Spin Interacting Quantum Field Theory and Higher Order Conformal Invariant Lagrangians
Quantum Field Theory Conformal Invariant Lagrangians
2010/12/22
This thesis includes several original results. All of them are already published or submitted for publication. I present here the short summary of main results: The ultraviolet singular structure of t...
Closing the Window on Strongly Interacting Dark Matter with IceCube
Super-heavy dark matter Simpzillas IceCube
2010/3/15
We use the recent results on dark matter searches of the 22-string IceCube detector to probe the remaining allowed window for strongly interacting dark matter in the mass range 10^4
Nearest-Neighbor Distributions and Tunneling Splittings in Interacting Many-Body Two-Level Boson Systems
Nearest-Neighbor Distributions Many-Body Two-Level Boson Systems Tunneling Splittings
2010/4/8
We study the nearest-neighbor distributions of the $k$-body Embedded Ensembles of Random Matrices for $n$ bosons distributed over two-degenerate single-particle states. This ensemble, as a function of...
Tachyonic field interacting with Scalar (Phantom) Field
acceleration tachyonic field scalar field phantom field
2010/7/5
In this letter, we have considered the universe is filled with the mixture of tachyonic field and scalar or phantom field. If the tachyonic field interacts with scalar or phantom field, the interactio...
