Solar Wind Penetration into Dusty Magnetospheres creates Electrostatic Waves and Structures
Usman Saeed, Shaukat Ali Shan, Hamid Saleem
The low frequency electrostatic perturbations have been investigated in a bi ion plasma in the background of static dust. It is shown that the field aligned shear flow of both the…
Messier 90 galactic halo rotation in the microwaves
F. De Paolis, V. G. Gurzadyan, A. L. Kashin +4
We used Planck data to study the Virgo Cluster's galaxy M 90 and its surroundings. We find, as in the case of certain galaxies of the Local Group and its vicinity, a substantial te…
Exploring Nonlinear Drift Waves: Limiting Cases and Dynamics
Hamid Saleem
A general equation for drift waves is derived incorporating both nonlinear electron density perturbation and ion vorticity effects. It is emphasized that the well-known Hasegawa-Mi…
3-D exact analytical solutions of two fluid plasma, MHD and neutral fluid equations for the creation of ordered structures as well as jet-like flows
Hamid Saleem, Zain H. Saleem
The 3-D exact analytical solutions of ideal two fluid plasma, single fluid plasma (MHD) and neutral fluid equations have been found using physically justifiable assumptions. Surpri…
Rotating baryonic dark halos
F. De Paolis, A. V. Gurzadyan, A. A. Nucita +8
Galactic halos are of great importance for our understanding of both the dark matter nature and primordial non-Gaussianity in the perturbation spectrum, a powerful discriminant of…
An Experimental Study of Shor's Factoring Algorithm on IBM Q
Mirko Amico, Zain H. Saleem, Muir Kumph
We study the results of a compiled version of Shor's factoring algorithm on the ibmqx5 superconducting chip, for the particular case of , and . The semi-classical qu…
Oscillating Entropy and Spin Precession in the Ensemble of Qubits Interacting with Thermal Systems
Xiaoyu He, Zain H. Saleem, Vladimir I. Tsifrinovich
We present a simple model which allows us to explain the physical nature of the oscillating entropy. We consider an ensemble of qubits interacting with thermal two-level systems. T…
Galaxy Rotation and Supermassive Black Hole Binary Evolution
Muhammad Awais Mirza, Afnan Tahir, Fazeel Mahmood Khan +4
Supermassive black hole (SMBH) binaries residing at the core of merging galaxies are recently found to be strongly affected by the rotation of their host galaxies. The highly eccen…
Dynamical spin effects in the pion
M. Ahmady, F. Chishtie, R. Sandapen
We take into account dynamical spin effects in the holographic light-front pion wavefunction in order to predict the pion radius, decay constant, the pion electromagnetic and photo…
Renormalization Scheme Dependence and the Renormalization Group Beta Function
F. A. Chishtie, D. G. C. McKeon
The renormalization that relates a coupling "a" associated with a distinct renormalization group beta function in a given theory is considered. Dimensional regularization and mass…
Shadow of a Charged Rotating Non-Commutative Black Hole
M. Sharif, Sehrish Iftikhar
This paper investigates the shadow of a charged rotating non-commutative black hole. For this purpose, we first formulate the null geodesics and study the effects of non-commutativ…
Renormalization Scheme Dependence in a QCD Cross Section
Farrukh Chishtie, D. G. C. McKeon, T. N. Sherry
The zero to four loop contribution to the cross section for hadrons, when combined with the renormalization group equation, allows for…
Extraordinary Drift Wave in Space and Cylindrically Bounded Heavy Ion Plasmas
Hamid Saleem, Usman Saeed
It is pointed out that electrostatic and electromagnetic waves propagating in perpendicular direction to the density gradient and external ma…
The Effective Potential in Non-Conformal Gauge Theories
F. T. Brandt, F. A. Chishtie, D. G. C. McKeon
By using the renormalization group (RG) equation it has proved possible to sum logarithmic corrections to quantities that arise due to quantum effects in field theories. In particu…
