More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that ...

A radical idea that resolves many quantum paradoxes suggests there is no objective view of reality. How can the cosmos be ...

Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

There is so much information about the world and life itself out there that it’s almost unfathomable. And every now and then, ...

Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

Researchers at Rensselaer Polytechnic Institute (RPI) have created a new and unusual state of matter—known as a supersolid—by ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...

Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s ...

Scientists observe a visible time crystal for the first time, revealing a phase of matter that repeats patterns through time.

Using a phenomenon called "negative light," scientists invisibly transferred data disguised as background thermal radiation.
