We investigate the phase diagram of the half-filled triangular-lattice Hubbard model using the density-matrix renormalization group method. By systematically studying the ground-state properties with the ratio of on-site Coulomb repulsion and bandwidth, we first identify two competing intermediate phases in the vicinity of metal-insulator transition on narrow cylinders with width Ly=3: a gapped chiral spin liquid phase and a gapless phase with stripy antiferromagnetic quasi-long-range order.

The observations of persistent revivals in the Rydberg atom chain have revealed a weak ergodicity breaking mechanism known as quantum many-body scars, which is typically a collection of states with low entanglement embedded in otherwise thermal spectra.

Abstract:In the process of production, processing, transportation, and storage of edible oils, the oils inevitably come into contact with plastic products. As a result, plasticizers migrate into edible oils, are harmful to human health, and can exhibit reproductive toxicity. Therefore, the determination of plasticizers in edible oils is very important, and a series of sample preparation methods and determination techniques have been developed for the determination of plasticizers in edible oils.
