Triangular ${J}_{1}\text{−}{J}_{2}$ Heisenberg antiferromagnet in a magnetic field (opens in new tab)

Author(s): T. Bader, S. Feng, S. Budaraju, F. Becca, J. Knolle, and F. PollmannThe behavior of the paradigmatic ${J}_{1}\text{−}{J}_{2}$ triangular lattice Heisenberg antiferromagnet in a magnetic field remains unsettled despite decades of study. We map out the phase diagram using three complementary approaches, including self-consistent nonlinear spin-wave theory, density-mat…[Phys. Rev. B 113, L241114] Published Thu Jun 18, 2026
