Superradiant and subradiant states in lifetime-limited organic molecules through laser-induced tuning
Christian Lange, Emma Daggett, Valentin Walther +2
An array of radiatively coupled emitters is an exciting new platform for generating, storing, and manipulating quantum light. However, the simultaneous positioning and tuning of mu…
Photon control and coherent interactions via lattice dark states in atomic arrays
Oriol Rubies-Bigorda, Valentin Walther, Taylor L. Patti +1
Ordered atomic arrays with subwavelength spacing have emerged as an efficient and versatile light-matter interface, where emitters respond collectively and form subradiant lattice…
Simulation of many-body dynamics using Rydberg excitons
Jacob Taylor, Sumit Goswami, Valentin Walther +3
The recent observation of high-lying Rydberg states of excitons in semiconductors with relatively high binding energy motivates exploring their applications in quantum nonlinear op…
Correlated many-body noise and emergent behavior in an anharmonic fluctuator model
P N Thomas Lloyd, Valentin Walther, Hossein Sadeghpour
Fluctuating electric fields emanating from surfaces are a primary source of decoherence in trapped ion qubits. Here, we show that superradiant phonon-induced excitation exchange be…
Photon-photon interactions in Rydberg-atom arrays
Lida Zhang, Valentin Walther, Klaus Mølmer +1
We investigate the interaction of weak light fields with two-dimensional lattices of atoms, in which two-photon coupling establishes conditions of electromagnetically induced trans…
