Time-resolved second harmonic generation probe
The coherent, time delay dependent oscillations in \(\varDelta {I}_{{SH}}\) induced by an infrared-active mode \({Q}_{i}({\omega }_{i})\) of a solid at frequency \({\omega }_{i}\) can be cast in the…

Terahertz chiral photonic-crystal cavities for Dirac gap engineering in graphene
Distinctions between chiral cavity types
Here, we provide a concise overview of the distinction between chiral cavities with broken mirror symmetry and those with broken TRS. Chiral matter exhibits different optical responses to LCP and RCP light….

Low-force pulse switching of ferroelectric polarization enabled by imprint field
Switching barrier lowering by imprint field
We first explain the strategy for enabling low-force polarization switching by introducing an imprint field via asymmetric electrostatic boundary conditions in ferroelectric materials. As known, the…

A novel framework for neutron-gamma density logging: semi-empirical modeling, directional neutron sources, and experimental benchmarking
Distribution of energy
In this section, a simulation was conducted using a sandstone model with dry conditions. The neutron beam was collimated at four angles (0°, 25°, 50°, and 75°) and the fluxes of both neutrons and gamma rays were recorded…

Spin-photon interaction between a ruby crystal and a high-critical-temperature superconducting microwave cavity
Sample and experimental setup
Ruby is a corundum (Al2O3) crystal, whose distinct red hue results from chromium dopants that replace some of the aluminum atoms. It can be manufactured artificially with a relatively low concentration of chromium,…
