Relativistic coupled-cluster investigation of parity (P) and time-reversal (T) symmetry violations in HgF
Kaushik Talukdar, Malaya K. Nayak, Nayana Vaval +1
We employ the -vector method in the four-component relativistic coupled-cluster framework to calculate the parity () and time-reversal () symmetry…
Static and dynamic polarizabilities of Yb-ion]{Accurate determination of black-body radiation shift, magic and tune-out wavelengths for the clock transition in Yb

We present precise values of the dipole polarizabilities () of the ground and metastable states of Yb, that are…
Relativistic equation-of-motion coupled-cluster method using open-shell reference wavefunction
Himadri Pathak, Sudip Sasmal, Malaya K. Nayak +2
The open-shell reference relativistic equation-of-motion coupled-cluster method within its four-component description is successfully implemented with the consideration of single-…
Relativistic coupled-cluster study of RaF as a candidate for parity and time reversal violating interaction
Sudip Sasmal, Himadri Pathak, Malaya K. Nayak +2
We have employed both Z-vector method and the expectation value approach in the relativistic coupled-cluster framework to calculate the scalar-pseudoscalar (S-PS) P, T -odd interac…
An Optimized Ion Trap Geometry to Measure Quadrupole Shifts of Yb Clocks
N. Batra, B. K. Sahoo, S. De
We propose a new ion-trap geometry to carry out accurate measurements of the quadrupole shifts in the Yb-ion. This trap will produce nearly ideal harmonic potential where t…
