Cover Story: The authors investigate the anomalous polarization in one-dimensional aperiodic insulators and demonstrate that multilevel charge pumping is a general feature in such systems, irrespective of the type of aperiodicity. By studying the Fibonacci, Tribonacci, and Thue–Morse chains, they confirm that aperiodic structures can exhibit topological insulating phases characterized by an anomalous edge response in the presence of inversion symmetry. The signatures of topological phases are identified by the Berry phase, the polarization response to electric fields, and degeneracies in the entanglement spectrum. The study highlights how inversion symmetry plays a crucial role in these systems, similar to periodic systems, confirming the bulk–boundary correspondence in aperiodic insulators and expanding the understanding of topological materials.

Based on DFT + DMFT, we investigate the orbital-nematic and s-wave superconducting states of a hole-doped NdNiO2 superconductor. We emphasize the role played by the interorbital proximity effect in determining the orbital-selective electronic state b...

Possible Superconductivity in Very Thin Magnesium Films

  • Giovanni Alberto Ummarino and
  • Alessio Zaccone

It is known that noble metals such as gold, silver and copper are not superconductors; this is also true for magnesium. This is due to the weakness of the electron–phonon interaction, which makes them excellent conductors but not superconductor...

  • Alfonso Maiellaro,
  • Claudio Guarcello,
  • Francesco Romeo and
  • Roberta Citro

We investigate spin-to-charge conversion via the Edelstein effect in a 2D Rashba electron gas using the semiclassical Boltzmann approach. We analyze the magnetization arising from the direct Edelstein effect, taking into account an anisotropic Rashba...

Strained Graphene as Pristine Graphene with a Deformed Momentum Operator

  • David Valenzuela,
  • Alfredo Raya and
  • Juan D. García-Muñoz

We explore the equivalence between the low-energy dynamics of strained graphene and a quantum mechanical framework for the 2D Dirac equation in flat space with a deformed momentum operator. By considering some common forms of the anisotropic Fermi ve...
