Zeros in the magic neutrino mass matrix
Radha Raman Gautam, Sanjeev Kumar
We study the phenomenological implications of the presence of two zeros in a magic neutrino mass matrix. We find that only two such patterns of the neutrino mass matrix are experim…
Many-body effects in a quasi-one-dimensional electron gas
Sanjeev Kumar, Kalarikad J. Thomas, Luke W. Smith +6
We have investigated electron transport in a quasi-one dimensional (quasi-1D) electron gas as a function of the confinement potential. At a particular potential configuration, and…
Electronic route to stabilize nanoscale spin textures in itinerant frustrated magnets
Sahinur Reja, Jeroen van den Brink, Sanjeev Kumar
We unveil novel spin textures in an itinerant fermion model on a frustrated triangular lattice in the limit of low electronic density. Using hybrid Monte Carlo simulations on finit…
Charged Compact Boson Stars and Shells in the Presence of a Cosmological Constant
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha
In this work we study the boson stars and boson shells in a theory involving massive complex scalar fields coupled to the U(1) gauge field and gravity in a conical potential in the…
Neutrino Mass Matrices with Generalized CP Symmetries and Texture Zeros
Sanjeev Kumar, Radha Raman Gautam
We investigate the properties of neutrino mass matrices that incorporate texture zeros and generalized CP symmetries associated with tribimaximal mixing. By combining these approac…
Tuning electrical properties of silicon dioxide through intrinsic nano-patterns
Subimal Majee, Devesh Barshilia, Debashree Banerjee +3
The inherent network of nanopores and voids in silicon dioxide (SiO2) is generally undesirable for aspects of film quality, electrical insulation and dielectric performance. Howeve…
