Low energy surface phonon dispersion of MoS2
The thermal and electronic performance of atomically thin semiconductors, a promising group of materials for electronics, is underpinned by their vibrational (phonon) dynamics. However, surface phonons in layered materials remain poorly understood due to limitations in conventional experimental techniques. We employ helium-3 spin-echo (HeSE) spectroscopy to measure the lowest energy (<10meV) dispersions of surface phonons on molybdenum disulfide (MoS2), a prototypical 2D semiconductor. We revea…

JENNA: [To Cally] You know what all this is about, don't you?
CALLY: [Nodding] I think I can guess.
JENNA: It is a trap, isn't it?
CALLY: Avon thinks so.
JENNA: Well Avon always thinks so.

Locomotion on Constrained Footholds via Layered Architectures and Model Predictive Control
Computing stabilizing and optimal control actions for legged locomotion in real time is difficult due to the nonlinear, hybrid, and high dimensional nature of these robots. The hybrid nature of the system introduces a combination of discrete and continuous variables which causes issues for numerical optimal control. To address these challenges, we propose a layered architecture that separates the choice of discrete variables and a smooth Model Predictive Controller (MPC). The layered formulatio…

X-ray diffraction from smectic multilayers: crossover from kinematical to dynamical regime
We study X-ray diffraction in smectic liquid crystal multilayers. Such systems are fabricated as freely suspended films and have a unique layered structure. As such, they can be described as organic Bragg mirrors with sub-nanometer roughness. However, an interesting peculiarity arises in the diffraction on these structures: the characteristic shape of diffraction peaks associated with dynamical scattering effects is not observed. Instead, the diffraction can be well described kinematically, whi…

Performance of MAGIC stellar intensity interferometer and expansion to MAGIC + CTAO-LST1 stellar intensity interferometer
A new generation of optical intensity interferometers are emerging in recent years taking advantage of the existing infrastructure of Imaging Atmospheric Cherenkov Telescopes (IACTs). The MAGIC SII (Stellar Intensity Interferometer) in La Palma, Spain, has been operating since its first successful measurements in 2019 and its current design allows it to operate regularly. The current setup is ready to follow up on bright optical transients, as changing from regular gamma-ray observations to SII…

Van der Waals waveguide quantum electrodynamics probed by infrared nano-photoluminescence
Atomically layered van der Waals (vdW) materials exhibit remarkable properties, including highly-confined infrared waveguide modes and the capacity for infrared emission in the monolayer limit. Here, we engineered structures that leverage both of these nano-optical functionalities. Specifically, we encased a photoluminescing atomic sheet of MoTe2 within two bulk crystals of WSe2, forming a vdW waveguide for the embedded light-emitting monolayer. The modified electromagnetic environment offered …
