Interplay of disorder and interactions in a flat-band supporting diamond chain
Physical Review Research, 2020 We systematically study the effect of disorder and interactions on a quasi-one-dimensional diamond chain possessing flat bands. Disorder localizes all the single-particle eigenstates, while at low disorder strengths, we obtain weak flat-band based ...

Exact solution of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chain
Condensed Matter Physics, 2009 The geometric frustration in a class of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chains is investigated by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation and transfer-matrix method.
