A Stochastic Cluster Expansion for Electronic Correlation in Large Systems

This paper introduces a stochastic cluster expansion framework that enables near-DMRG accuracy for total correlation energies in large condensed-phase systems by combining exactly treated subspaces with randomly sampled environment orbitals, thereby eliminating the need for prior active space selection and facilitating high-accuracy studies of chemical processes in complex environments.

Tuning Optoelectronic Properties and Photoelectrochemical Performance of \b{eta}-TaON via Vanadium Doping

This study demonstrates that vanadium doping (up to 10 at.%) effectively enhances the photoelectrochemical performance of phase-pure β\beta-TaON by narrowing its bandgap, improving carrier mobility, and optimizing band edge positions for water splitting, while higher doping concentrations induce detrimental secondary phases that degrade performance.

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.
