Quantum physics may sound abstract, but Ph.D. candidates Kirsten Kanneworff and David Dechant show that quantum research can also be very concrete. Together, they are investigating how quantum ...

A team of theoretical researchers has found duality can unveil non-invertible symmetry protected topological phases, which ...

Physicists saw excitons, a type of quasiparticle, undergo a reversible phase transition from superfluid to supersolid for the first time, opening new doors for studying extreme states of matter.

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

John von Neumann came about as close as humanly possible to embodying the Platonic ideal of a genius. Conversant in ancient Greek by age 6, the Hungarian made significant mathematical advances in his ...

They combined optical tweezers with metasurfaces to trap more than 1,000 atoms, with the potential to capture hundreds of ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

To alumnus Gal Weitz (EngrPhys, ApMath’22), Boulder was a “dream destination” for undergrad. Now working in quantitative finance, Weitz shares how his education at CU Boulder set him up for success in ...
