Single- and two-mode magnon thermal squeezing - Nature Physics
- Researchers observed single-mode thermal squeezing of magnetization fluctuations in YIG films under microwave parametric excitation.
- The study also demonstrates two-mode squeezing as correlated fluctuations of magnons on opposing surfaces of the film.
- Control of thermal squeezing in magnetic systems offers insights into fluctuation dynamics and quantum effects in magnets.
- The work uses parametric pumping to tune magnon modes and study squeezing phenomena.
- Extended data include temperature dependence and numerical simulations supporting the experimental results.
- Authors provide data and code access upon reasonable request, enabling reproducibility.
- The publication places magnon squeezing in the context of quantum magnonics and related quantum optics concepts.
- The study acknowledges support from JST CREST, JST PRESTO, and other Japanese research programs.
- The article reports potential implications for observing quantum effects in magnetic films.
- Authors confirm no competing interests and acknowledge peer review by Nature Physics.
