Enhanced Multifractality Induced by Non-Hermitian Disorder in Quantum Percolation
W. S. Oliveira, Julian Faundez, Rodrigo Arouca +1
We investigate the interplay between geometric dilution and non-Hermitian disorder in the two-dimensional quantum site-percolation model. Non-Hermiticity is introduced through rand…

Berezinskii-Kosterlitz-Thouless Transition and Multifractal Critical Phase in Two-Dimensional Quantum Percolation
W. S. Oliveira, J. Pimentel de Lima, F. A. Pinheiro +1
We present a numerical study of the two-dimensional quantum percolation model, revealing that a critical region with multifractal eigenstates mediates the transition from localized…

Quantum percolation on Lieb Lattices
W. S. Oliveira, J. Pimentel de Lima, Raimundo R. dos Santos
We theoretically investigate the quantum percolation problem on Lieb lattices in two and three dimensions. We study the statistics of the energy levels through random matrix theory…
