The product of two independent Su-Schrieffer-Heeger chains yields a two-dimensional Chern insulator
Bruno Mera
We provide an extensive look at Bott periodicity in the context of complex gapped topological phases of free fermions. In doing so, we remark on the existence of a product structur…
Interferometric geometry from symmetry-broken Uhlmann gauge group with applications to topological phase transitions
Hector Silva, Bruno Mera, Nikola Paunković
We provide a natural generalization of a Riemannian structure, i.e., a metric, recently introduced by Sjöqvist for the space of non degenerate density matrices, to the degenerate c…
On the minmax regret for statistical manifolds: the role of curvature
Bruno Mera, Paulo Mateus, Alexandra M. Carvalho
Model complexity plays an essential role in its selection, namely, by choosing a model that fits the data and is also succinct. Two-part codes and the minimum description length ha…
Localization anisotropy and complex geometry in two-dimensional insulators
Bruno Mera
The localization tensor is a measure of distinguishability between insulators and metals. This tensor is related to the quantum metric tensor associated with the occupied bands in…
