Almost invariant subspaces in the topologically non-trivial setting: a pedestrian approach

Horia Cornean, Gabriele Peluso, Mikkel Hviid Thorn

We present a self-contained, algorithmic construction of almost invariant subspaces [Panati et al. (2003), De Nittis and Panati (2010), Freund and Teufel (2016)] for Hofstadter-lik…

Absolute and relative invariants for low-dimensional topological insulators

Federico Manzoni, Domenico Monaco, Gabriele Peluso

[An extended abstract is provided in-text] Motivated by topological insulators, this paper analyzes classification schemes for projection-valued maps on -dimensional tori, $d \l…

The Zak phase in topologically insulating chains: invariants and limitations

Federico Manzoni, Domenico Monaco, Gabriele Peluso

In this work we investigate the topological content of the Zak phase in one-dimensional translation-invariant topological insulators endowed with time-reversal, particle-hole and/o…

Zak phase and bulk-boundary correspondence in a generalized Dirac-Kronig-Penney model

Giuliano Angelone, Domenico Monaco, Gabriele Peluso

We investigate the topological properties of a generalized Dirac--Kronig--Penney model, a continuum one-dimensional model for a relativistic quantum chain. By tuning the coupling p…

Splitting obstructions and invariants in time-reversal symmetric topological insulators

Alessandro Ferreri, Domenico Monaco, Gabriele Peluso

The Fu-Kane-Mele index characterizes two-dimensional time-reversal symmetric topological phases of matter. We shed some light on some features of this index by inves…

Moduli space of spin connections on three-dimensional homogeneous spaces

Matteo Bruno, Gabriele Peluso

In this manuscript, we aim to classify and characterize the moduli space of homogeneous spin connections and homogeneous SU(2) connections on three-dimensional Riemannian homogeneo…

A invariant for chiral and particle-hole symmetric topological chains

Domenico Monaco, Gabriele Peluso

We define a -valued topological and gauge invariant associated to any 1-dimensional, translation-invariant topological insulator which satisfies either particle-hole…
