Quantum spin-current noise of magnons

Nakata, Koki ; Onuma, Yuichi*; Matsuo, Mamoru*

Using the Keldysh formalism, we calculate a magnonic current-noise and compare it with the current-noise of electrically charged electrons. We thus discuss the universality of current-noise against the difference of quantum-statistical properties of bosons and fermions.
