Synthesizing electromagnetically induced transparency without a control field in waveguide QED using small and giant atoms
Andreas Ask, Yao-Lung L. Fang, Anton Frisk Kockum
The absorption of photons in a three-level atom can be controlled and manipulated by applying a coherent drive at one of the atomic transitions. The situation where the absorption…
Breaking time-reversal and translational symmetry at edges of -wave superconductors: microscopic theory and comparison with quasiclassical theory
N. Wall Wennerdal, A. Ask, P. Holmvall +2
We report results of a microscopic calculation of a second-order phase transition into a state breaking time-reversal and translational invariance along pair-breaking edges of -…
Engineering the Level Structure of a Giant Artificial Atom in Waveguide Quantum Electrodynamics
A. M. Vadiraj, Andreas Ask, T. G. McConkey +4
Engineering light-matter interactions at the quantum level has been central to the pursuit of quantum optics for decades. Traditionally, this has been done by coupling emitters, ty…
Towards phonon routing: Controlling propagating acoustic waves in the quantum regime
M K Ekström, T Aref, A Ask +5
We explore routing of propagating phonons in analogy with previous experiments on photons. Surface acoustic waves (SAWs) in the microwave regime are scattered by a superconducting…
Cavity-free vacuum-Rabi splitting in circuit quantum acoustodynamics
Andreas Ask, Maria Ekström, Per Delsing +1
Artificial atoms coupled to surface acoustic waves (SAWs) have played a crucial role in the recent development of circuit quantum acoustodynamics (cQAD). In this paper, we have inv…
