Electrically tunable artificial gauge potential for polaritons
Hyang-Tag Lim, Emre Togan, Martin Kroner +2
Neutral particles subject to artificial gauge potentials can behave as charged particles in magnetic fields. This fascinating premise has led to demonstrations of one-way waveguide…
Observation of the exciton Mott transition in the photoluminescence of coupled quantum wells
Gabija Kiršanskė, Petru Tighineanu, Raphaël S. Daveau +3
Indirect excitons in coupled quantum wells have long radiative lifetimes and form a cold quasi-two-dimensional population suitable for studying collective quantum effects. Here we…
Electron mean free path from angle-dependent photoelectron spectroscopy of aerosol particles
Maximilian Goldmann, Javier Miguel-Sánchez, Adam H. C. West +2
We propose angle-resolved photoelectron spectroscopy of aerosol particles as an alternative way to determine the electron mean free path of low energy electrons in solid and liquid…
Photonic nano-structures on (111) oriented diamond
Elke Neu, Patrick Appel, Marc Ganzhorn +7
We demonstrate the fabrication of single-crystalline diamond nanopillars on a (111)-oriented chemical vapor deposited diamond substrate. This crystal orientation offers optimal cou…
Polariton boxes in a tunable fiber cavity
Benjamin Besga, Cyril Vaneph, Jakob Reichel +5
Cavity-polaritons in semiconductor photonic structures have emerged as a test bed for exploring non-equilibrium dynamics of quantum fluids in an integrated solid-state device setti…
Observation of quantum jumps of a single quantum dot spin using sub-microsecond single-shot optical readout
Aymeric Delteil, Wei-bo Gao, Parisa Fallahi +2
Single-shot read-out of individual qubits is typically the slowest process among the elementary single- and two-qubit operations required for quantum information processing. Here,…
Quantum Teleportation from a Propagating Photon to a Solid-State Spin Qubit
Wei-bo Gao, P. Fallahi, E. Togan +4
The realization of a quantum interface between a propagating photon used for transmission of quantum information, and a stationary qubit used for storage and manipulation, has long…
Nonequilibrium dynamics in an optical transition from a neutral quantum dot to a correlated many-body state
F. Haupt, S. Smolka, M. Hanl +5
We investigate the effect of many-body interactions on the optical absorption spectrum of a charge-tunable quantum dot coupled to a degenerate electron gas. A constructive Fano int…
Cavity quantum electrodynamics with charge-controlled quantum dots coupled to a fiber Fabry-Perot cavity
J. Miguel-Sanchez, A. Reinhard, E. Togan +5
We demonstrate non-perturbative coupling between a single self-assembled InGaAs quantum dot and an external fiber-mirror based microcavity. Our results extend the previous realizat…
