Probing disorder-induced Fisher information matrix and Cramér-Rao bound by STM
Lucas A. Oliveira, Wei Chen
The electronic local density of states of solids, if normalized correctly, represents the probability density that the electron at a specific position has a particular energy. Beca…
Real space quantum metric of solids
Lucas A. Oliveira, Wei Chen
By applying the projector to the filled lattice eigenstates on a specific position, or applying the local electron annihilation operator on the many-body ground state, one can cons…
David regularity of the Yoccoz extension
Luna Lomonaco, Lucas Oliveira, Miguel Ratis Laude
A central problem in the study of critical circle dynamics is understanding the regularity of Yoccoz conjugators - circle homeomorphisms that conjugate critical circle maps with ir…
On the Uniqueness of the Norton-Sullivan Quasiconformal extension
José Afonso Barrionuevo, Felipe Gonçalves, José Victor Medeiros +1
We show that the extension map \[ \mathcal{E}_{NS}(f)(z)=\frac{f(x+y)+f(x-y)}{2}+i\frac{f(x+y)-f(x-y)}{2}\mbox{ for all }z=x+iy\in\mathbb{H}\,, \] defined by Norton and Sullivan in…
Robustness of topological order against disorder
Lucas A. Oliveira, Wei Chen
A universal topological marker has been proposed recently to map the topological invariants of Dirac models in any dimension and symmetry class to lattice sites. Using this topolog…
Four interacting spins: addition of angular momenta, spin-spin correlation functions, and entanglement
Raimundo R. dos Santos, Lucas Alves Oliveira, Natanael C. Costa
We study four spins on a ring coupled through competing Heisenberg interactions between nearest neighbors, , and next-nearest neighbors, . The spectrum is obtaine…
Unsupervised machine learning approaches to the -state Potts model
Andrea Tirelli, Danyella O. Carvalho, Lucas A. Oliveira +3
In this paper with study phase transitions of the -state Potts model, through a number of unsupervised machine learning techniques, namely Principal Component Analysis (PCA), $k…
