Impurity-induced magnetization in three dimensional antiferromagnet at quantum critical point
Yaroslav A. Kharkov, Ivan S. Terekhov, Oleg P. Sushkov
We consider a single impurity with spin embedded in a three-dimensional antiferromagnetic system which is close to the quantum critical point (QCP), separating magnetically ord…

Casimir effect mechanism of pairing between fermions in the vicinity of a magnetic quantum critical point
Yaroslav A. Kharkov, Oleg P. Sushkov
We consider two immobile spin fermions in a two-dimensional magnetic system that is close to the magnetic quantum critical point (QCP) which separates magnetically or…
