FSRCC two-valence calculations of clock transition properties, dipole polarizability and isotope shifts in Fermionic and Bosonic Sr
Palki Gakkhar, D Angom, B K Mani
We employ an all-particle multireference Fock-space relativistic coupled-cluster (FSRCC) theory to study the clock transition in both Fermionic an…
Probing transition rates, nuclear moments and electric dipole polarizability in nobelium using multireference FSRCC and PRCC theories
Ravi Kumar, Palki Gakkhar, D. Angom +1
We employ an all-particle multireference Fock-space relativistic coupled-cluster (FSRCC) theory to compute the ionization potential, excitation energy, transition rate and hyperfin…
Disordered solid to Bose-glass transition in Bose-Hubbard model with disorder and long-range interactions
Kohenjit Pebam, Laxmi Angom, Bhumika Thoudam +3
The introduction of disorder in Bose-Hubbard model gives rise to new glassy quantum phases, namely the Bose-glass (BG) and disordered solid (DS) phases. In this work, we present th…
Fock-space perturbed relativistic coupled-cluster calculations of electric dipole polarizability and nuclear spin-dependent parity non-conservation in Cs
Suraj Pandey, Ravi Kumar, D. Angom +1
We implement the Fock-space perturbed relativistic coupled-cluster theory to compute the electric dipole polarizability of ground and low lying excited states, and nuclear spin-dep…
Exact diagonalization using hierarchical wave functions and calculation of topological entanglement entropy
Deepak Gaur, Hrushikesh Sable, D. Angom
In this work we describe a new technique for numerical exact diagonalization. The method is particularly suitable for cold bosonic atoms in optical lattices, in which multiple atom…
