Predissociation dynamics of negative ion resonances of H near 12 eV and 14.5 eV using velocity slice imaging technique
Akshay Kumar, Suvasis Swain, Jankee Upadhyay +3
Dissociative electron attachment (DEA) is an important tool for investigating negative ion resonances. We have studied the negative ion resonances of H2 at 10 eV and 14 eV using th…
Quantum coherence in molecular dynamics induced by inelastic free electron scattering
Akshay Kumar, Suvasis Swain, Vaibhav S. Prabhudesai
This paper presents the inversion symmetry breaking observed in ion-pair formation from molecular hydrogen on electron impact. We explain these observations using quantum interfere…
Gyrogroup extensions and semi cross product
Akshay Kumar, Mani Shankar Pandey, Seema Kushwaha +1
The aim of the article is to study the extension theory of gyrogroups under certain conditions. Consequently, we see that there is an equivalence between the category GEXT of group…
Gyrogroup through its Grothendieck Group Completion and Right gyrogroup action
Akshay Kumar, Mani Shankar Pandey, Seema Kushwaha +1
In this article, we discuss the Grothendieck group completion (GGC) of a gyrogroup. Consequently, we show that there is a one to one correspondence between actions and representati…
Low temperature carrier transport mechanism and photoconductivity of WSe2
Manjot Kaur, Kulwinder Singh, Ishant Chauhan +5
This work reports the electrical transport and temperature-dependent photoconductivity in tungsten diselenide (WSe2) thin films. The electrical conductivity analysis shows the pres…
Specially designed B4C/SnO2 nanocomposite for photocatalysis: traditional ceramic with unique properties
Paviter Singh, Gurpreet Kaur, Kulwinder Singh +7
Boron carbide: A traditional ceramic material shows unique properties when explored in nano-range. Specially designed boron based nanocomposite has been synthesized by reflux metho…
Insights of preferred growth, elemental and morphological properties of BN/SnO2 composite for photocatalytic applications towards organic pollutants
Bikramjeet Singh, Kulwinder Singh, Manjeet Kumar +1
Boron nitride (BN) has been explored these days because of its extraordinary optical, chemical and mechanical properties. BN is sensitive to its crystal structure that slight chang…
Order by Disorder and by Doping in Quantum Hall Valley Ferromagnets
Akshay Kumar, S. A. Parameswaran, S. L. Sondhi
We examine the Si(111) multi-valley quantum Hall system and show that it exhibits an exceptionally rich interplay of broken symmetries and quantum Hall ordering already near intege…
Generalizing Quantum Hall Ferromagnetism to Fractional Chern Bands
Akshay Kumar, Rahul Roy, S. L. Sondhi
We study the interplay between quantum Hall ordering and spontaneous sublattice symmetry breaking in multiple Chern number bands at fractional fillings. Primarily we study fermions…
Microscopic Theory of a Quantum Hall Ising Nematic: Domain Walls and Disorder
Akshay Kumar, S. A. Parameswaran, S. L. Sondhi
We study the the interplay between spontaneously broken valley symmetry and spatial disorder in multivalley semiconductors in the quantum Hall regime. In cases where valleys have a…
Flat bands with local Berry curvature in multilayer graphene
Akshay Kumar, Rahul Nandkishore
We demonstrate that flat bands with local Berry curvature arise naturally in chiral (ABC) multilayer graphene placed on a boron nitride (BN) substrate. The degree of flatness can b…
