Field-resolved high-order sub-cycle nonlinearities in a terahertz semiconductor laser

Light: Science & Applications, 2021
The exploitation of ultrafast electron dynamics in quantum cascade lasers (QCLs) holds enormous potential for intense, compact mode-locked terahertz (THz) sources, squeezed THz light, frequency mixers, and comb-based metrology systems.

Ultrafast two-dimensional field spectroscopy of terahertz intersubband saturable absorbers. [PDF]

Optics Express, 2019
Intersubband (ISB) transitions in semiconductor multi-quantum well (MQW) structures are promising candidates for the development of saturable absorbers at terahertz (THz) frequencies. Here, we exploit amplitude and phase-resolved two-dimensional (2D) THz

An algorithmic approach to Rupert's problem [PDF]

Mathematics of Computation, 2021
A polyhedron $\textbf{P} \subset \mathbb{R}^3$ has Rupert's property if a hole can be cut into it, such that a copy of $\textbf{P}$ can pass through this hole.

Fast range expansion of the red imported fire ant in Virginia and prediction of future spread in the United States

Ecosphere, Volume 14, Issue 8, August 2023., 2023
Abstract The red imported fire ant (RIFA), Solenopsis invicta (Buren), is a notorious, invasive species with broad impacts on ecosystems, economies, and human health. While incidental reports to the Virginia Department of Agriculture and Consumer Services (VDACS) indicate a recent range expansion in Virginia, the full extent of RIFA spread in the area ...

Investigating Adsorption of Cellulose Nanocrystals at Air–Liquid and Substrate–Liquid Interfaces after pH Manipulation

Advanced Materials Interfaces, Volume 10, Issue 11, April 14, 2023., 2023
An “additive‐free” method for dip coating of cellulose nanocrystal (CNCs) monolayers is developed. Electrostatic interactions are exploited in the pH window between pH 2 and 4 where the air–water interface is positively charged and CNCs are negatively charged.

The 2017 terahertz science and technology roadmap

Journal of Physics D: Applied Physics, 2017
Science and technologies based on terahertz frequency electromagnetic radiation (100 GHz–30 THz) have developed rapidly over the last 30 years. For most of the 20th Century, terahertz radiation, then referred to as sub-millimeter wave or far-infrared ...
