Flat-band-based multifractality in the all-band-flat diamond chain
Aamna Ahmed, Ajith Ramachandran, Ivan M. Khaymovich +1
We study the effect of quasiperiodic Aubry-André disorder on the energy spectrum and eigenstates of a one-dimensional all-bands-flat (ABF) diamond chain. The ABF diamond chain poss…
Interplay of disorder and interactions in a flat-band supporting diamond chain
Nilanjan Roy, Ajith Ramachandran, Auditya Sharma
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 eigenstat…
Fano Resonances in Flat Band Networks
Ajith Ramachandran, Carlo Danieli, Sergej Flach
Linear wave equations on Hamiltonian lattices with translational invariance are characterized by an eigenvalue band structure in reciprocal space. Flat band lattices have at least…
