  • Studying the high pressure phase diagram of hydrogen experimentally or by simulations presents significant challenges. Here, the authors apply a combined molecular dynamics and many-body quantum Monte Carlo approach, finding that the molecular liquid phase is stable at higher pressures than previously believed.

  • Electron or hole doping in a Mott insulator leads to superconductivity, with the mechanism obscured by multi-orbital Fermi surface reconstructions. Here, Kawasugi et al. report doping dependent Hall coefficients and resistivity anisotropy of an organic Mott insulator, revealing doping asymmetry of reconstructed Fermi surface of a single electronic orbital.

  • The strong interaction between electron spin and orbital degrees of freedom in 5d oxides can lead to exotic electronic ground states. Here the authors use resonant inelastic X-ray scattering to demonstrate that the theoretically proposed J eff = 3/2 state is realised in GaTa4Se8.

  • Electron-phonon correlations are integral to understand the properties of conventional superconductors but it is also thought they may be important for unconventional high-Tc superconductivity. Here, the authors investigate the interplay between antiferromagnetic ordering and charge density wave formation in 2D square lattice Hubbard-Holstein model at half-filling using unbiased quantum Monte Carlo simulations, and demonstrate an intermediate phase with enhancement of s-wave pairing correlations.
