Collective excitations in chiral spin liquid: chiral roton and long-wavelength nematic mode

Hongyu Lu, Wang Yao, Wei Zhu

Chiral spin liquids host a low-energy chiral p-wave roton at finite momentum and a higher-energy d-wave nematic mode at zero momentum.

Claims

C1strongest claim

we observe two spin-singlet collective modes: a chiral p-wave (low-energy) roton mode at finite momentum and a elliptically polarized d-wave (higher-energy) nematic mode at zero momentum, both of which are prominent across the CSL phase.

C2weakest assumption

The numerical methods (exact diagonalization on small clusters and time-dependent variational principle) faithfully capture the collective modes without significant finite-size artifacts or variational bias in the identified chiral spin liquid regime.

C3one line summary

Numerical calculations reveal a chiral p-wave roton mode at finite momentum and a d-wave nematic mode at zero momentum in the SU(2) symmetric chiral spin liquid phase of the J1-J2-Jχ model.
