TU Wien Produces an Extremely Simple and Compact Source of Terahertz Radiation

Terahertz radiation has a wavelength of typically a little less than one millimetre - a technically difficult range. Electromagnetic waves with longer wavelengths can be generated with ordinary electronic components (such as transistors) and antennas.

Experimental Realization of Atom-Optically Synthetic Gauge Field for a Noninteracting Bose Gas

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to charge neutral systems by engineering an analog Hamiltonian that governs the effective dynamics of neutral particles subject to magnetic fields.

Review: Recent Progress and Applications of Hyperbolic Metamaterials

Hyperbolic metamaterials (HMMs), which have an extremely high anisotropy with a hyperbolic dispersion relation, are rising as an innovative method of manipulating light. HMMs have received tremendous interest in photonics for their applicability to various fields such as super-resolution imaging, negative refraction, and emission engineering.

Novel Technique to Simulate Light-Matter Interactions at the Atomic Scale

Light–matter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers from Japan have developed a technique that overcomes these limitations.

Integration of Optical Sensing into Orthopedic Surgical Devices

Knees and hips wear out. Backs and necks become unstable. Fortunately, orthopedic surgeons specialize in musculoskeletal repair. And surgeries that formerly required open exposure are now accomplished with minimally invasive techniques. Surgical risks are reduced, as are postoperative pain and recovery time.
