A Study of the Low-Energy Spectrum and Phase Structure of a Yang-Mills Matrix Model
Yang-Mills theory is a non-Abelian gauge theory based on the gauge group SU(N), and lies at the heart of the QCD, the theory underlying strong interactions. Due to the fundamental property of asymptotic freedom, a study ... -
A Study Of The Metric Induced By The Robin Function
(2013-09-13)Let D be a smoothly bounded domain in Cn , n> 1. For each point p _ D, we have the Green function G(z, p) associated to the standard sum-of-squares Laplacian Δ with pole at p and the Robin constant __ Λ(p) = lim G(z, p) ... -
Study of the Thermoelectric Properties of RxCo4Sb12 (R=In, Ba) with InSb/GaSb Nano Inclusions
Almost 80% of the world’s energy needs depend on oil, coal and natural gases. Use of natural gases, fossil fuels emit a large amount of CO2 to the earth’s atmosphere, which causes the greenhouse effect and results in an ... -
A Study of the X-ray Variability and Accretion Mechanism in High Mass X-ray Binary Pulsars
High-mass X-ray binaries are among the most luminous X-ray sources. They host an accreting compact object (more often a neutron star) and a massive (M > 10 M⊙) donor star. They are among the earliest discovered X-ray sources ... -
