Magnon squeezing in an antiferromagnet: Reducing the spin noise below the standard quantum limit

Mostrar todas las versiones(2)

The quantum squeezing of a collective spin-wave excitation (magnon) was investigated using femtosecond optical pulses. The quantum squeezed magnon was used to generate correlations involving pairs of spins in an antiferromagnetic insulator MnF2. It was found that the fluctutations of the magnetizati...
