Photon Correlation Spectroscopy as a Probe of Critical Fluctuations in Correlated Electron Systems
Natasha Kiper, Bertrand Evrard, Yuya Shimazaki +5
Characterizing phase transitions between correlated electronic phases, extracting their critical exponents, and identifying their universality class are of central interest in many…
Quantum correlations and dissipative blockade of polaritons in a tunable fiber cavity
Gian-Marco Schnüriger, Martin Kroner, Emre Togan +5
Cavity exciton--polaritons are quasiparticles that form when quantum well excitons hybridize with a cavity mode. Here, we carry out photon correlation measurements under continuous…
Optical Injection and Detection of Long-Lived Interlayer Excitons in van der Waals Heterostructures
Alperen TüÄen, Anna M. Seiler, Arthur Christianen +4
Interlayer excitons in semiconducting bilayers separated by insulating hBN layers constitute a promising platform for investigation of strongly correlated bosonic phases. Here, we…
Single Photon Emitters in Ultra-Thin Hexagonal Boron Nitride Layers
Le Liu, Igor Khanonkin, Johannes Eberle +6
Single-photon emitters (SPE) in hexagonal boron nitride (h-BN) are promising for applications ranging from single-photon sources to quantum sensors. Previous studies exclusively fo…
AC-Stark Spectroscopy of Interactions between Moiré Excitons and Polarons
B. Evrard, H. S. Adlong, A. A. Ghita +6
We use nonlinear pump-probe spectroscopy to study optical excitations in a charge-tunable MoSe\WS moiré heterostructure. An intense red-detuned laser pulse creates a photo…
