Optical Barium Ion Qubit
Dahyun Yum, Debashis De Munshi, Tarun Dutta +1
We demonstrate an optical single qubit based on 6S1/2 to 5D5/2 quadrupole transition of a single Ba+ ion operated by diode based lasers only. The resonance wavelength of the 6S1/2…
An exacting transition probability measurement - a direct test of atomic many-body theories
T. Dutta, D. De Munshi, D. Yum +2
A new protocol for measuring the branching fraction of hydrogenic atoms with only statistically limited uncertainty is proposed and demonstrated for the decay of the P leve…
Precision measurement of branching fractions of Ba: Testing many body theories below one percent level
D. De Munshi, T. Dutta, R. Rebhi +1
The branching fractions from the excited state of singly charged barium ion has been measured with a precision in an ion trap experiment. This measurement along…
Signature of Non-Abelian to Abelian Transition in Spin Systems Through Geometric Phase
Debashis De Munshi, Manas Mukherjee
Abelian and Non-Abelian evolution of a quantum system manifests differently in the geometric phase acquired by the system under such evolutions. In this work we develop and study,…
Space charge and collective oscillation of ion cloud in a linear Paul trap
P. Mandal, S. Das, D. De Munshi +2
The presence of charged particles in an ion trap modifies the harmonic trapping potential in which they are trapped, leading to observed shifts in secular frequency as well as appe…
Berry Phase Generation and Measurement in a Single Trapped Ion
D. De Munshi, M. Mukherjee, B. Dutta-Roy
In this work, we propose a new design of an ion trap which can enable us to generate state specific Berry phase in a single trapped ion. Such a design will enable us to study the p…
An atomic clockwork using phase dependent energy shifts
D. De Munshi, B. Dutta-Roy, M. Mukherjee
A frequency stabilized laser referenced to an unperturbed atomic two level system acts as the most accurate clock with femtosecond clock ticks. For any meaningful use, a Femtosecon…
