Bouncing cosmological models in a functional form of F(R) gravity
A. S. Agrawal, S. Mishra, S. K. Tripathy +1
We have investigated some bouncing cosmological models in an isotropic and homogeneous space time with the F(R) theory of gravity. Two functional forms of F(R) have been investigat…
Element-specific probe of quantum criticality in
A. Khansili, R. Sharma, R. Hissariya +11
Employing the elemental sensitivity of x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD), we study the valence and magnetic order in the heavy fermio…
Anharmonic Phonons and Anomalous Thermal Expansion of Graphite
Ranjan Mittal, Mayanak K. Gupta, Baltej Singh +2
We have investigated the anisotropic thermal expansion of graphite using ab-initio calculation of lattice dynamics and anharmonicity of the phonons, which reveal that the negative…
Textured heterogeneity in square artificial spin ice
J. C. T Lee, S. K. Mishra, V. S. Bhat +8
We report evidence of spontaneous formation of a heterogeneous network of superdomains in two-dimensional square artificial spin ice nanostructures in externally applied magnetic f…
Raman studies on nanocomposite silicon carbonitride thin film deposited by RF magnetron sputtering at different substrate temperatures
A. S. Bhattacharyya, S. K. Mishra
Raman studies of nanocomposite SiCN thin film by sputtering showed that with an increase of substrate temperature from room temperature to 500oC, a transition from mostly sp2 graph…
Magnetically Charged Superdomain Walls In Square Artificial Spin Ice
J. C. T Lee, S. K. Mishra, V. S. Bhat +8
We report direct evidence that magnetically charged superdomain walls form spontaneously in two dimensional square artificial spin ice nanostructures in response to external magnet…
