  • In many quantum materials, different electronic phases can coexist or compete with one another. In this work uniaxial pressure is used to achieve the spatial distribution of charge order that maximizes the superconducting transition temperature.

  • While it is widely believed that high-temperature superconductivity in cuprate materials arises from an intertwined interplay between charge and spin fluctuations, the microscopic coupling between charge and spin degrees of freedom still remains a mystery in these materials. Here, the authors profit from neutron scattering with superior beam focusing to probe the subtle spin-density wave order under uniaxial pressure, and demonstrate that charge and spin orders respond to the external tuning parameter in the same manner.

  • Unconventional superconductivity in the cuprates involves a complex interplay of competing charge and spin orders, making it challenging to elucidate the underlying mechanisms. Here, the authors apply uniaxial pressure to tune LBCO, and using muon spin rotation and AC susceptibility, reveal a gradual suppression of Tc under c-axis stress–contrasting with its strong enhancement under in plane stress–and show that c axis compression leaves spin stripe order intact while in plane stress strongly suppresses it.

  • The honeycomb lattice is of fundamental importance for understanding quantum spin liquids and frustrated magnetism more generally. Here, the authors use inelastic neutron scattering to investigate the honeycomb antiferromagnet YbCl3 showing how quantum effects renormalize the single-magnon and multimagnon excitations, shedding further light on the mechanisms of quantum magnetism in honeycomb-lattice compounds.
