Fock-space perturbed relativistic coupled-cluster theory for electric dipole polarizability of one-valence atomic systems: Application to Al and In
Ravi Kumar, D. Angom, B. K. Mani
We have developed a Fock-space relativistic coupled-cluster theory based method for the calculation of electric dipole polarizability of one-valence atoms and ions. We employ this…
Observation of ballistic upstream modes at fractional quantum Hall edges of graphene
Ravi Kumar, Saurabh Kumar Srivastav, Christian Spånslätt +5
The structure of edge modes at the boundary of quantum Hall (QH) phases forms the basis for understanding low energy transport properties. In particular, the presence of ``upstream…
X-ray Absorption Spectroscopy Study of LaSrCoNbO
Rishabh Shukla, Ajay Kumar, Ravi Kumar +2
We use x-ray absorption spectroscopy to investigate the local structure and electronic properties of bulk LaSrCoNbO ( 2 as LSCNO and 0 as…
RCC calculation of electric dipole polarizability and correlation energy of Cn, Nh and Og: Correlation effects from lighter to superheavy elements
Ravi Kumar, S. Chattopadhyay, D. Angom +1
We employ a fully relativistic coupled-cluster theory to calculate the ground-state electric dipole polarizability and electron correlation energy of superheavy elements Cn, Nh…
Hall Effect for Dirac Electrons in Graphene Exposed to an Abrikosov Flux Lattice
Jonathan Schirmer, Ravi Kumar, Vivas Bagwe +6
The proposals for realizing exotic particles through coupling of quantum Hall effect to superconductivity involve spatially non-uniform magnetic fields. As a step toward that goal,…
Vanishing thermal equilibration for hole-conjugate fractional quantum Hall states in graphene
Saurabh Kumar Srivastav, Ravi Kumar, Christian Spånslätt +5
Transport through edge-channels is responsible for conduction in quantum Hall (QH) phases. Topology dictates quantization of both charge and thermal transport coefficients. These t…
