When optical materials (molecules or solid-state semiconductors) are embedded in tiny photonic boxes, known as optical microcavities, they form hybrid light-matter states known as polaritons. Most of ...

Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations—virtual photons popping in and out of existence that can interact with matter, giving rise to new, ...

A new study reports on a deep new probe into the interface between the theories of gravity and quantum mechanics, using ultra-high energy neutrino particles detected by a particle detector set deep ...

Quantum computing has been touted as a revolutionary advance that uses our growing scientific understanding of the subatomic world to create a machine with powers far ...

The Casimir effect is a quantum phenomenon in which two materials, when placed close together, can be attracted or repelled by quantum fluctuations. A new study from researchers at the Chinese Academy ...

In a collider ring on Long Island, physicists have turned a long standing thought experiment into hard data, watching new particles emerge from what once looked like empty space. By tracing the birth ...

Theoretical physicists are trying to understand how the many possibilities that exist in quantum physics can become 'real.' A new model developed by UC Davis researchers suggests that there may be ...

This illustration shows how tiny quantum irregularities in the newborn universe can be stretched and amplified during cosmic inflation, eventually seeding the large-scale structure of the cosmos.
