Spin superfluidity, coherent spin precession

and magnon BEC

S

pin superfluidity, coherent spin precession, and

magnon BEC are intensively investigated theoretically

and experimentally nowadays. Meanwhile, clear definition

and differentiation between these related phenomena is

needed. Spin superfluidity is defined as a possibility of

dissipation less spin transport on macroscopical distances

with sufficiently large spin supercurrents. This possibility

is realized at special topology of the magnetic-order-

parameter space, such as, e.g., that in easy-plane ferro-

and antiferromagnets, or in coherent precession states

supported by pumping of energy and magnons. Recent

claims on experimental observation of spin superfluidity

(in yttrium-iron-garnet magnetic films, in particular) are

discussed.

Biography

Edouard B Sonin is an Emeritus Professor at the Hebrew University of Jerusalem,

Israel. His research interests focus on the superfluidity theory and the vortex

dynamics in superfluids, superconductors, and magnetically ordered materials. He

has over 230 publications including two books.
