Journal Article
Niranjan, A., Li, W., & Nath, R. (2020). Landau-Zener transitions and adiabatic impulse approximation in an array of two Rydberg atoms with time-dependent detuning. Physical Review A, 101(6), https://doi.org/10.1103/physreva.101.063415

We study the Landau-Zener (LZ) dynamics in a setup of two Rydberg atoms with time-dependent detuning, both linear and periodic, using both the exact numerical calculations as well as the method of adiabatic impulse approximation (AIA). By varying the... Read More about Landau-Zener transitions and adiabatic impulse approximation in an array of two Rydberg atoms with time-dependent detuning.

Controlling the dynamical scale factor in a trapped atom Sagnac interferometer (2020)
Journal Article

Sagnac interferometers with massive particles promise unique advantages in achieving high-precision measurements of rotation rates over their optical counterparts. Recent proposals and experiments are exploring nonballistic Sagnac interferometers whe... Read More about Controlling the dynamical scale factor in a trapped atom Sagnac interferometer.

Robust Rydberg gate via Landau-Zener control of Förster resonance (2018)
Journal Article
Huang, X., Ding, Z., Hu, C., Shen, L., Li, W., Wu, H., & Zheng, S. (2018). Robust Rydberg gate via Landau-Zener control of Förster resonance. Physical Review A, 98(5), Article 052324. https://doi.org/10.1103/physreva.98.052324

In this paper, we propose a scheme to implement the two-qubit controlled-Z gate via the Stark-tuned Förster interaction of Rydberg atoms, where the Förster defect is driven by a time-dependent electric field of a simple sinusoidal function while the...
