Article Synopsis
- Quasi two-dimensional organic superconductors exhibit complex behaviors due to strong electron correlations, including unconventional superconductivity, metal-insulator transitions, and unique magnetic properties.
- The study uses the Hubbard model on an anisotropic triangular lattice to analyze these compounds, employing advanced quantum embedding techniques that respect the lattice's symmetry.
- Findings indicate a transition from Fermi liquid metal to Mott insulator linked to a pseudogap, with a distinctive pattern in the Fermi surface that inspires further experimental research, aligning well with the existing phase diagrams of κ-BEDT organics.
The relationship between the pseudogap and underlying ground-state phases has not yet been rigorously established. We investigated the doped two-dimensional Hubbard model at finite temperature using controlled diagrammatic Monte Carlo calculations, allowing for the computation of spectral properties in the infinite-size limit and with arbitrary momentum resolution. We found three distinct regimes as a function of doping and interaction strength: a weakly correlated metal, a correlated metal with strong interaction effects, and a pseudogap regime at low doping.

Calls play a crucial role in the mating displays of anurans, and the negative impact of anthropogenic noise-induced auditory masking has been reported in several species. We investigated the acoustic variation in 96 males (971 calls) of the treefrog across acoustically undisturbed sites and different noise conditions, associated with urban areas (URBAN) and roads (ROAD), in Central Argentina.

- This study investigated the use of effective learning techniques among secondary school students, comparing research-backed strategies to commonly used but less effective ones.
- Results indicated that only proven techniques (besides distributed practice) had a positive link to academic achievement and were more correlated with positive student attitudes like self-efficacy and growth mindset.
- The findings highlight the importance of adopting research-supported learning strategies to enhance both academic performance and students' beliefs about their learning abilities.
We introduce a spin-symmetry-broken extension of the connected determinant algorithm [Riccardo Rossi, Determinant diagrammatic Monte Carlo algorithm in the thermodynamic limit, Phys. Rev. Lett.
