Lopsided fish show that symmetry is only skin deep

Putting function before form, members of the Perissodinus genus of fish have developed a hugely lopsided jaw that provides a distinct feeding advantage. Research published in the open access journal BMC Biology describes ...

The building blocks for exploring new exotic states of matter

Topological insulators act as electrical insulators on the inside but conduct electricity along their surfaces. Researchers study some of these insulators' exotic behavior using an external magnetic field to force the ion ...

Dual-polarization two-dimensional valley photonic crystals

The introduction of topology in photonic systems has attracted considerable attention not only for the elaborate molding of light but also for its practical applications in novel photonic devices. Originally, the quantum ...

When light loses symmetry, it can hold particles

Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous ...

Polarimetric parity-time-symmetric photonic system

Parity-time-symmetric photonic and optoelectronic systems are being intensively explored recently, which has been bringing about significant fundamental physics and technological outcomes. One of the main characteristics ...
