Physicists Use Quantum Mechanics to Pull Energy out of Nothing
The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.
The Physics Principle That Inspired Modern AI Art
Diffusion models generate incredible images by learning to reverse the process that, among other things, causes ink to spread through water.
Why This Universe? A New Calculation Suggests Our Cosmos Is Typical.
Two physicists have calculated that the universe has a higher entropy — and is therefore more likely — than alternative possible universes.
Controversy Continues Over Whether Hot Water Freezes Faster Than Cold
Decades after a Tanzanian teenager initiated study of the “Mpemba effect,” the effort to confirm or refute it is leading physicists toward new theories about how substances relax to equilibrium.
Physicists Rewrite the Fundamental Law That Leads to Disorder
The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.
Beyond the Second Law
Thanks to the power of fluctuation relations, physicists are taking the second law of thermodynamics to settings once thought impossible.
At the Dawn of Life, Heat May Have Driven Cell Division
A mathematical model shows how a thermodynamic mechanism could have made protocells split in two.
The New Thermodynamic Understanding of Clocks
Investigations of the simplest possible clocks have revealed their fundamental limitations — as well as insights into the nature of time itself.
How Maxwell’s Demon Continues to Startle Scientists
The thorny thought experiment has been turned into a real experiment — one that physicists use to probe the physics of information.
