CP violating effects in $^{210}$Fr and prospects for new physics beyond the Standard Model

Autor: Shitara, Nanako, Yamanaka, Nodoka, Sahoo, Bijaya Kumar, Watanabe, Toshio, Das, Bhanu Pratap

Publikováno v: JHEP02(2021)124

We report theoretical results of the electric dipole moment (EDM) of $^{210}$Fr which arises from the interaction of the EDM of an electron with the internal electric field in an atom and the scalar-pseudoscalar electron-nucleus interaction; the two

Two component quantum walk in one-dimensional lattice with hopping imbalance

Autor: Giri, Mrinal Kanti, Mondal, Suman, Das, Bhanu Pratap, Mishra, Tapan

Publikováno v: Sci Rep 11, 22056 (2021)

We investigate the two-component quantum walk in one-dimensional lattice. We show that the inter-component interaction strength together with the hopping imbalance between the components exhibit distinct features in the quantum walk for different ini

Random Phase Approximation For allowed and Parity Non-conserving Electric Dipole Transition Amplitudes and its connection with Many-Body Perturbation Theory and Coupled Cluster Theory

Autor: Gopakumar, Geetha, Sur, Chiranjib, Das, Bhanu Pratap, Chaudhuri, Rajat K., Mukherjee, D., Hirao, Kimihiko

The connections between the Random Phase Approximation (RPA) and Many-Body Perturbation Theory (MBPT) and its all order generalisation, the Coupled- Cluster Theory (CCT) have been explored. Explicit expressions have been derived for the electric dipo

The Parity Non-Conserving 3P0--1P1 E1 Transition Amplitude of the Atomic Yb

Autor: Singh, Angom Dilip, Das, Bhanu Pratap

The atomic parity non-conservation(PNC) experiments has reached accuracies which have important implications for physics beyond the standard model. An optical rotation experiment to measure the atomic PNC of the 3P1(6s6p)--1P1(6s6p) in Yb was propose

Coupled Electron Pair Approximation Calculation of the Electric Dipole Moment of Atomic Yb

Autor: Singh, Angom Dilip, Das, Bhanu Pratap, Mukherjee, Debashis

The existence of a finite electric dipole moment (EDM) d_a of the closed-shell atom Yb implies parity and time reversal violations involving the nuclear sector. An important effect which can contribute to the Yb EDM is the tensor-pseudotensor electro
