Twistoptics—A new way to control optical nonlinearity

Nonlinear optics, a study of how light interacts with matter, is critical to many photonic applications, from the green laser pointers we're all familiar with to intense broadband (white) light sources for quantum photonics ...

New microcomb could help discover exoplanets and detect diseases

Tiny photonic devices could be used to find new exoplanets, monitor health, and make the internet more energy efficient. Researchers from Chalmers University of Technology, Sweden, now present a game-changing microcomb that ...

Factoring in gravitomagnetism could do away with dark matter

Observations of galactic rotation curves give one of the strongest lines of evidence pointing towards the existence of dark matter, a non-baryonic form of matter that makes up an estimated 85% of the matter in the observable ...

A potential model for a real physical warp drive

A pair of researchers at Applied Physics has created what they describe as the first general model for a warp drive, a model for a space craft that could travel faster than the speed of light, without actually breaking the ...

Terahertz waves from electrons oscillating in liquid water

Ionization of water molecules by light generates free electrons in liquid water. After generation, the so-called solvated electron is formed, a localized electron surrounded by a shell of water molecules. In the ultrafast ...

Research contributes to understanding of hypersonic flow

Using data collected in a NASA Langley Mach 6 wind tunnel, researchers at the University of Illinois Urbana-Champaign replicated the hypersonic flow conditions of a compression ramp flow by means of Direct Numerical Simulation. ...

Thin explosive films provide snapshot of how detonations start

Using thin films—no more than a few pieces of notebook paper thick—of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow. Sandia is the only lab ...

Molybdenum disulfide ushers in era of post-silicon photonics

Researchers of the Center for Photonics and Two-Dimensional Materials at MIPT, together with their colleagues from Spain, Great Britain, Sweden, and Singapore, including co-creator of the world's first 2-D material and Nobel ...

Reading the physics hiding in data

Information is encoded in data. This is true for most aspects of modern life, but it is also true in most branches of contemporary physics, and extracting useful and meaningful information from very large data sets is a key ...
