Observation of the 87Rb 5S1/2 to 4D3/2 electric quadrupole transition at 516.6 nm mediated via an optical nanofibre [PDF]
New Journal of Physics, 2020 Light guided by an optical nanofibre has a very steep evanescent field gradient extending from the fibre surface. This gradient can be exploited to drive electric quadrupole transitions in nearby quantum emitters.

Lamb Dip of a Quadrupole Transition in H_{2}. [PDF]
Physical Review Letters, 2023 The saturated absorption spectrum of the hyperfineless S(0) quadrupole line in the (2-0) band of H_{2} is measured at λ=1189 nm, using the NICE-OHMS technique under cryogenic conditions (72 K).

Control of an Atomic Quadrupole Transition in a Phase-Stable Standing Wave. [PDF]
Physical Review Letters, 2022 Using a single calcium ion confined in a surface-electrode trap, we study the interaction of electric quadrupole transitions with a passively phase-stable optical standing wave field sourced by photonics integrated within the trap.

Transfer of angular momentum of guided light to an atom with an electric quadrupole transition near an optical nanofiber [PDF]
Physical Review A, 2022 We study the transfer of angular momentum of guided photons to a two-level atom with an electric quadrupole transition near an optical nanofiber. We show that the generation of the axial orbital torque of the driving guided field on the atom is governed by

High-order correction calculation for survival of Rydberg atoms in intense laser fields
Results in Physics, 2021 Using a method based on the Magnus expansion, the survival of Rydberg atoms in intense laser fields is studied. Usually, for atoms in intense laser fields, effects beyond the electric dipole approximation need to be considered.
