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…

This paper reports calculations of interlayer electrical and thermal resistivity in a layered metal assuming Fermi-liquid quasiparticles inelastically scattered by two-dimensional antiferromagnetic spin fluctuations. The model yields linear-in-temperature behavior over a broad range and suggests that extrapolations…
