Three Dimensional Ising Model, Percolation Theory and Conformal Invariance
Abbas Ali Saberi, Horr Dashti-Naserabadi
The fractal structure and scaling properties of a 2d slice of the 3d Ising model is studied using Monte Carlo techniques. The percolation transition of geometric spin (GS) clusters…
Polarized Deeply Inelastic Scattering (DIS) Structure Functions for Nucleons and Nuclei
Ali N. Khorramian, S. Atashbar Tehrani, S. Taheri Monfared +2
We extract parton distribution functions (PDFs) and structure functions from recent experimental data of polarized lepton-DIS on nucleons at next-to-leading order (NLO) Quantum Chr…
Fields Annihilation and Particles Creation in DBI inflation
Hassan Firouzjahi, Salomeh Khoeini-Moghaddam
We consider a model of DBI inflation where two stacks of mobile branes are moving ultra relativistically in a warped throat. The stack closer to the tip of the throat is annihilate…
Level Crossing Analysis of Cosmic Microwave Background Radiation: A method for detecting cosmic strings
M. Sadegh Movahed, Shahram Khosravi
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of l…
A novel method to extract dark matter parameters from neutrino telescope data
Arman Esmaili, Yasaman Farzan
Recently it has been shown that when the Dark Matter (DM) particles captured in the Sun directly annihilate into neutrino pairs, the oscillatory terms in the oscillation probabilit…
Light-Like Noncommutativity, Light-Front Quantization and New Light on UV/IR Mixing
M. M. Sheikh-Jabbari, A. Tureanu
We revisit the problem of quantizing field theories on noncommutative Moyal spacetime with \emph{light-like} noncommutativity. To tackle the issues arising from noncommuting and he…
