Quantum renormalization group of XY model in two dimensions
M. Usman, Asif Ilyas, Khalid Khan
We investigate entanglement and quantum phase transition (QPT) in a two-dimensional Heisenberg anisotropic spin-1/2 XY model, using quantum renormalization group method (QRG) on a…

The extra scalar degrees of freedom from the two Higgs doublet model for dark energy
Muhammad Usman, Asghar Qadir
In principle a minimal extension of the standard model of Particle Physics, the two Higgs doublet model, can be invoked to explain the scalar field responsible of dark energy. The…

Constraints on Two Higgs Doublet Model Parameters in the light of rare -Decays
Mureed Hussain, Muhammad Usman, Muhammad Ali Paracha +1
We established the allowed parameters of two-Higgs doublet model(2HDM) from flavor physics observables, precisely from rare meson decays. In our analysis most formidable constr…
