  • The authors introduce a new spectroscopic technique for studying Higgs modes in superconductors and apply it to a cuprate superconductor. The method involves a soft quench of the Mexican-Hat potential, populating Higgs modes of different symmetries, which are then probed by non equilibrium anti-Stokes Raman scattering.

  • Interaction between Cooper pairs and other collective excitations may reveal important information about the pairing mechanism. Here, the authors observe a universal jump in the phase of the driven Higgs oscillations in cuprate thin films, indicating the presence of a coupled collective mode, as well as a nonvanishing Higgs-like response at high temperatures, suggesting a potential nonzero pairing amplitude above Tc.

  • A liver-intrinsic mechanism is presented that suppresses effective anti-hepatitis virus B responses in mice and humans by rendering virus-specific CD8 T cells refractory to activation causing loss of effector functions.

  • Cuprate superconductors are known for their intertwined interactions and coexistence of competing orders. Here, the authors observe a Fano resonance in the nonlinear THz response of La2-xSrxCuO4, which may arise from a coupling between superconducting and charge-density-wave amplitude fluctuations.

  • RNA of some viruses is protected from degradation by a 5′ triphosphate group. Here the authors identify nudix hydrolase 2 (NUDT2) as novel antiviral defense protein that dephosphorylates viral RNA and thereby enables its degradation.
