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…
