1Physics Department and Center for Particle Physics and Field Theory, Fudan University, Shanghai 200433, China.
Rotating trapped Fermi gases with spin-orbit coupling exhibit chiral magnetic and separation effects, analogous to those in quark-gluon plasma. These findings suggest atomic gases can simulate these quantum phenomena.
Area of Science:
- Condensed Matter Physics
- Quantum Simulation
- Atomic Physics
Background:
- Chiral magnetic and separation effects are quantum-anomaly-induced phenomena studied in quark-gluon plasma.
- These effects involve electric currents along magnetic fields in parity-odd systems.
Purpose of the Study:
- To investigate analogous chiral effects in rotating trapped Fermi gases.
- To explore the role of Weyl-Zeeman spin-orbit coupling and rotation in simulating these phenomena.
Main Methods:
- Theoretical analysis of rotating trapped Fermi gases with Weyl-Zeeman spin-orbit coupling.
- Investigating the induction of mass quadrupole moments along the rotation axis.
Main Results:
- Analogous chiral magnetic and separation effects were identified in the studied atomic gases.
- Rotation in these systems effectively mimics an external magnetic field.
Conclusions:
- Rotating spin-orbit coupled Fermi gases can serve as simulators for chiral magnetic and separation effects.
- The induced mass quadrupole moment offers a potential experimental signature for future verification.

The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
