Ferroelectricity in Magnon Bose-Einstein Condensate
Analysis
This paper explores a novel ferroelectric transition in a magnon Bose-Einstein condensate, driven by its interaction with an electric field. The key finding is the emergence of non-reciprocal superfluidity, exceptional points, and a bosonic analog of Majorana fermions. This work could have implications for spintronics and quantum information processing by providing a new platform for manipulating magnons and exploring exotic quantum phenomena.
Key Takeaways
- •Investigates ferroelectric instability in a magnon Bose-Einstein condensate.
- •Highlights the role of the Aharonov-Casher phase in mediating the interaction with an electric field.
- •Predicts non-reciprocal superfluidity and exceptional points.
- •Identifies a bosonic analog of a Majorana fermion at the critical point.
