Comparative studies of dipole polarizabilities in Sr, Ba and Ra and their applications to optical clocks
B. K. Sahoo, R. G. E. Timmermans, B. P. Das +1
Static dipole polarizabilities are calculated in the ground and metastable states of Sr, Ba and Ra using the relativistic coupled-cluster method. Trends of the electron…
Supersolid and solitonic phases in one-dimensional Extended Bose-Hubbard model
Tapan Mishra, Ramesh V. Pai, S. Ramanan +2
We report our findings on quantum phase transitions in cold bosonic atoms in a one dimensional optical lattice using the finite size density matrix renormalization group method in…
Induced supersolidity in a normal and hardcore boson mixture
Tapan Mishra, Ramesh V. Pai, B. P. Das
It is well known that the supersolid form of matter can arise in a single species of cold bosonic atoms in an optical lattice due to long range interactions. We present a scenario…
Relativistic Theory of the Electric Dipole Moment of an Atom due to the Electric Dipole Moment of an Electron
Debashis Mukherjee, B. K. Sahoo, H. S. Nataraj +1
The relativistic theory for the electric dipole moment (EDM) of paramagnetic atoms arising from the electric dipole moment of the electron is presented. A novel approach using the…
Probing CP violation with the electric dipole moment of atomic mercury
K. V. P. Latha, D. Angom, B. P. Das +1
The electric dipole moment of atomic Hg induced by the nuclear Schiff moment and tensor-pseudotensor electron-nucleus interactions has been calculated. For this, we have de…
Relativistic coupled-cluster studies of ionization potentials, lifetimes and polarizabilities in singly ionized calcium
B. K. Sahoo, B. P. Das, D. Mukherjee
Using the relativistic coupled-cluster method, we have calculated ionization potentials, E1 matrix elements and dipole polarizabilities of many low-lying states of Ca. Contribu…
