Luttinger's Theorem Violation and Green's Function Topological Invariants in a Fractional Chern Insulator

Using exact diagonalization of the fermionic Harper-Hofstadter-Hubbard model, this study demonstrates the violation of Luttinger's theorem in fractional Chern insulators and elucidates how the fractional many-body Chern number and integer Green's function invariants are encoded in the Středa responses of the Luttinger integral and count, respectively, while proposing an experimental protocol to extract these topological invariants via local density-of-states measurements.

Spontaneous Polarization Suppression of Exciton-Exciton Annihilation in 3R-Stacked MoS2_2 Bilayers

This study demonstrates that the spontaneous polarization inherent in 3R-stacked MoS2_2 bilayers suppresses exciton-exciton annihilation through repulsive dipole-dipole interactions, thereby enabling high-density excitonic regimes essential for efficient optoelectronic applications.

Strongly entangled Quantum Spin Rings driven by Hückel rule

This paper demonstrates that on-surface synthesized carbon-based macrocycles composed of [2]triangulene units exhibit strongly entangled quantum spin states governed by Hückel aromaticity rules, revealing non-trivial antiferromagnetic order in even-membered rings and frustrated ground states in odd-membered rings beyond the conventional Heisenberg model.

Non-Fermi-liquid behaviour of electrons coupled to gauge phonons

This paper identifies overdamped gauge phonons, which couple to electronic currents in Dirac materials, as a new microscopic mechanism driving non-Fermi-liquid behavior without requiring proximity to a quantum critical point, thereby offering a promising explanation for anomalous metallic states in systems like twisted bilayer graphene.
