Photoinduced frustration modulation in <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>κ</mml:mi></mml:math>-type quantum spin liquid candidates
The authors demonstrate here ultrafast vibrational control of electronic properties in two $\ensuremath{\kappa}$-type organic quantum spin liquid candidates. By coherently driving local molecular modes with midinfrared pulses, they reveal nonlinear coupling to long-range phonons that directly modulate the geometric frustration of the triangular lattice. This work introduces a new strategy to tune frustration in quantum materials and control quantum spin liquid states in correlated electron systems.
