Physicists create a bizarre new quantum state called a fractional fermi sea
Physicists have uncovered a strange new form of quantum behavior in which particles organize themselves in ways that challenge established theories.
Physicists have uncovered a strange new form of quantum behavior in which particles organize themselves in ways that challenge established theories.
The short version
- Even more surprising, the particles maintain a remarkable hidden order despite being driven into an extremely energetic state.
- Rather than simply becoming disordered, the particles rearrange themselves into an unusual configuration that behaves differently from the quantum systems scientists have traditionally studied.
- The theoretical findings provide the foundation for recent experimental research conducted by Nägerl's team at the Department of Experimental Physics.
What happened
Under ordinary conditions, quantum particles follow well-established rules that determine how they arrange themselves, particularly at extremely low temperatures. One important example involves fermions, a category of particles that includes electrons.
Why it matters
These particles cannot all occupy the same quantum state, so they fill available energy levels according to specific restrictions.
