From compact localized states to many-body scars in the random quantum comb
Oliver Hart, Giuseppe De Tomasi, Claudio Castelnovo
Abstract
This work explores the behavior of quantum particles hopping on a comb-like lattice with structural disorder. The authors find a family of exact states with strictly zero localization length, which survive the addition of interactions.
