This theoretical/physics study analyzes the spectrum of electron-phonon complexes in monolayer graphene in a perpendicular quantizing magnetic field. It reports that near the threshold of optical phonon emission, standard perturbation theory fails for calculating the scattering amplitude. The authors describe new…

This theoretical/physics study investigates spectral properties of a spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice in a magnetic field. It reports that interchain interactions in a magnetic field generate dominant modes that behave as quasiparticles, featuring anomalous incommensurate…
