Control of dynamical instability in semiconductor quantum nanostructures diode lasers: role of phase-amplitude coupling
Pramod Kumar, Frédéric Grillot
We numerically investigate the complex nonlinear dynamics for two independently coupled laser systems consisting of (i) mutually delay-coupled edge emitting diode lasers and (ii) i…
Sm2Al: Another ferromagnet with spin-orbital compensation?
Pramod Kumar, K. G. Suresh, A. K. Nigam
We report the observation of a compensation point in the temperature dependence of magnetization data of polycrystalline Sm2Al. Magnetization measurements show that this compound m…
Role of coexisting ferromagnetic and antiferromagnetic phases on the magnetocaloric effect in metamagnetic Tb2Ni2Sn
Pramod Kumar, Niraj K. Singh, K. G. Suresh +1
We report the anomalous magnetocaloric behavior in the polycrystalline compound Tb2Ni2Sn. The magnetization measurements show that this compound shows multiple magnetic transitions…
Correlated Non-Gaussian phase fluctuations in LaAlO/SrTiO heterointerface
Gopi Nath Daptary, Shelender Kumar, Pramod Kumar +4
We probe the existence of large correlated non-Gaussian phase fluctuations in the vicinity of the superconducting phase transition in the conducting layer residing at the interface…
An algorithm based on DQM with modified trigonometric cubic Bsplines for solving coupled viscous Burgers equations
Brajesh Kumar Singh, Pramod Kumar
This paper deals with a new algorithm called modified trigonometric cubic B-spline differential quadrature method for numerical computation of the time dependent partial differenti…
Upper critical field, critical current density and thermally activated flux flow in CaFFe0.9Co0.1As superconductor
Chandra Shekhar, Amit Srivastava, Pramod Kumar +2
In this paper, we report the synthesis, structure, transition temperature, upper critical field, critical current density and thermally activated flux flow in CaFFe0.9Co0.1As super…
