All-optical switching of nonlinear structured light in crystal-engineered van der Waals materials
Paolo Valisa, Marc Richstaetter, Bianca Sanfilippo +9
The orbital angular momentum (OAM) of light is a discrete, unbounded degree of freedom that underpins mode-multiplexed communications and high-dimensional quantum photonics. Yet, d…
Quantum Light Nano-Imaging
Michael Dapolito, Matthew Fu, Fuyang Tay +20
Entanglement and quantum correlations are central to the physics of quantum materials, yet they have remained notoriously difficult to access experimentally. Accessing these phenom…
Scaling native entanglement generation in layered semiconductors with quasi-phase matching
Benjamin Braun, Andrea Alessandrini, Josip Bajo +10
Efficient generation of entangled photons typically relies on spontaneous parametric down-conversion (SPDC) in phase-matched macroscopic nonlinear media. However, generating entang…
Purcell enhancement of photogalvanic currents in a van der Waals plasmonic self-cavity
Xinyu Li, Jesse Hagelstein, Gunda Kipp +23
Cavities provide a means to manipulate the optical and electronic responses of quantum materials by selectively enhancing light-matter interaction at specific frequencies and momen…
Flat band excitons in a three-dimensional supertwisted spiral transition metal dichalcogenide
Yinan Dong, Yuzhou Zhao, Lennart Klebl +19
A new frontier in van der Waals twistronics is the development of three-dimensional (3D) supertwisted materials, where each successive atomic layer rotates by the same angle. While…
Van der Waals waveguide quantum electrodynamics probed by infrared nano-photoluminescence
Samuel L. Moore, Hae Yeon Lee, Nicholas Rivera +15
Atomically layered van der Waals (vdW) materials exhibit remarkable properties, including highly-confined infrared waveguide modes and the capacity for infrared emission in the mon…
