Interacting second-order topological insulators in one-dimensional fermions with correlated hopping
A. Montorsi, U. Bhattacharya, Daniel González-Cuadra +3
Higher-order topological crystalline phases in low-dimensional interacting quantum systems represent a challenging and largely unexplored research topic. Here, we derive a Hamilton…
Spin-Resolved Topology and Partial Axion Angles in Three-Dimensional Insulators
Kuan-Sen Lin, Giandomenico Palumbo, Zhaopeng Guo +8
Symmetry-protected topological crystalline insulators (TCIs) have primarily been characterized by their gapless boundary states. However, in time-reversal- (-) invaria…
Emergent Dynamics of Spacetime and Matter from a Topological Phase
Giandomenico Palumbo
In this paper, we present a new theoretical scenario in which both dynamical Dirac fermions and Einstein's gravity with a positive cosmological constant and torsion emerge via a sp…
Topological Electromagnetic Effects and Higher Second Chern Numbers in Four-Dimensional Gapped Phases
Yan-Qing Zhu, Zhen Zheng, Giandomenico Palumbo +1
Higher-dimensional topological phases play a key role in understanding the lower-dimensional topological phases and the related topological responses through a dimensional reductio…
