Extending the uncertainty principle by using an unbounded operator

New way to charge batteries harnesses the power of ‘indefinite causal order’

In the classical world, if you tried to charge a battery using two chargers, you would have to do so in sequence, limiting the available options to just two possible…

First direct observation of spin quadrupole moments in a spin-nematic phase

Physicists discover new quantum phases in low-dimensional polar systems

a Phase diagram of PZT films as a function of electric field from CMC calculations (P = 1). a1-a5 Selected topological patterns from the last configuration of CMC simulations for Phases I,…

Researchers observe a hallmark quantum behavior in bouncing droplets

MIT mathematicians tracked a droplet as it bounced through a structure inspired by the theoretical “quantum bomb test.” The shows the droplet’s trajectories when the “bomb” is present, and the…

A superconducting junction made from a single 2D material promises to harness strange new physics

A schematic image showing a Josephson junction (central section) made from a single layer of tungsten telluride. The red spheres are electron with spin up, while the blue ones have…

Diamond quantum sensors measure neuron activity

Schematic of the sensor operation (not to scale), where green laser light directed to subsurface colour centres (NV) in the diamond enables recording of magnetic field arising from compound action…

Physicists ‘entangle’ individual molecules for the first time, hastening possibilities for quantum computing

Polaritons open up a new lane on the semiconductor highway

On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But those phonons don’t remove enough heat at the nanoscale of today’s most…
