What’s “inside” a black hole? Are they portals to another universe, or are actually other universes in miniature? Those are ...

A Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, ...

Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into the basic laws of physics but instead emerges from gravity’s effect on heat ...

This article investigates the classical limit of the Jarzynski equality in quantum systems, specifically using a nonlinear Jaynes-Cummings model ...

Despite significant mathematical refinements, econometrics has shown the weaknesses of its logical underpinnings, primarily during economic turning points—financial crises, pandemics, and geopolitical ...

A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Blue lasers with surface gratings are delivering quantum precision from millimetre footprints. The visible spectrum is an exciting frontier for laser diode technology. Here emerging applications exist ...
