For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'.

Experimental Investigation of External Optical Injection and its Application in Gain-Switched Wavelength Tunable Optical Frequency Comb Generation A detailed experimental investigation of the effects ...

The model allows one to estimate the large downshift of resonant frequency and the bandwidth utilizing a simple formula. When used in a subresonant regime, the unit cell may have a dimension of a ...

Quantum mechanics looks at how things work at the atomic and subatomic levels, where particles behave in ways that seem ...

Astronomers from Bulgaria and Egypt have performed multi-wavelength observations of a well-known blazar designated S5 ...

New research finds that not only will climate change make heat waves hotter and longer, but the lengthening of heat waves ...

In this study, the authors take a foundational step toward creating a general equation of state for liquids based on phonon theory. If successful, such a model could have wide-ranging applications in ...

A frequency distribution is a representation, either in a graphical or tabular format, that counts how often a specific item happens.

Sub-wavelength optics articles from across Nature Portfolio Sub-wavelength optics is the study of light on a spatial scale smaller than its wavelength. Conventionally, the minimum length scale on ...

Your Connecticut car tax bill should have come in the mail this week, and viewers kept asking the I-Team why they were paying more this year if their car is getting older.

Fluid dynamics, a cornerstone of applied mathematics and engineering, investigates the behaviour of fluids in motion. Within this broad field, active scalar equations play a pivotal role by ...
