Bose glass behavior in (Yb${}_{1-x}$Lu${}_x$)${}_4$As${}_3$ representing the randomly diluted quantum spin-1/2 chains

G. Kamieniarz, R. Matysiak, P. Gegenwart +2

The site-diluted compound (Yb${}_{1-x}$Lu${}_x$)${}_4$As${}_3$ is a scarce realization of the linear Heisenberg antiferromagnet partitioned into finite-size segments and is an ideal model…
