Localized-basis formulation of interacting Hamiltonians in flat topological bands: coherent states and coherent-like states for fractional physics

This paper proposes a unified framework for describing fractional quantum Hall systems and fractional Chern insulators by extending the concept of coherent states to Chern bands via "coherent-like states," enabling the construction of a localized-basis Hamiltonian that exhibits topological degeneracy and zero-energy ground states across both systems.

From interface-limited to Auger-dominated carrier dynamics in ππ-SnS

Using element-specific attosecond transient absorption spectroscopy, this study reveals that carrier dynamics in metastable cubic π\pi-SnS transition from interface-limited recombination at low densities to Auger-dominated processes at high densities, while also demonstrating strong coupling between electronic excitation and coherent lattice phonons.

Stacking-Tunable Electronic Properties in Recently Synthesized Hydrogen-Substituted Graphdiyne

This study employs first-principles calculations to demonstrate that hydrogen-substituted graphdiyne (HsGDY) is a thermally robust, indirect semiconductor with a 0.89 eV band gap in its energetically favorable AA stacking configuration, exhibiting strong visible-to-UV optical absorption that positions it as a promising candidate for next-generation optoelectronic and energy-harvesting applications.

On the challenge of simulating dipolar contributions to spin relaxation with generalized cluster correlation expansion methods

This paper demonstrates that the standard generalized Cluster-Correlation Expansion (gCCE) method fails to provide even a qualitatively accurate description of spin-spin relaxation at low temperatures, and offers a mathematical deconstruction of the theory to identify the root causes of this breakdown for future resolution.
