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…
