Kinetically inhibited order in a diamond-lattice antiferromagnet.
Frustrated magnetic systems exhibit highly degenerate ground states and strong fluctuations, often leading to new physics. An intriguing example of current interest is the antiferromagnet on a diamond lattice, realized physically in A-site spinel materials. This is a prototypical system in three dimensions where frustration arises from competing interactions rather than purely geometric constra...
متن کاملDirac semimetal in three dimensions.
We show that the pseudorelativistic physics of graphene near the Fermi level can be extended to three dimensional (3D) materials. Unlike in phase transitions from inversion symmetric topological to normal insulators, we show that particular space groups also allow 3D Dirac points as symmetry protected degeneracies. We provide criteria necessary to identify these groups and, as an example, prese...
متن کاملNegative magnetoresistance in Dirac semimetal Cd3As2
A large negative magnetoresistance (NMR) is anticipated in topological semimetals in parallel magnetic fields, demonstrating the chiral anomaly, a long-sought high-energy-physics effect, in solid-state systems. Recent experiments reveal that the Dirac semimetal Cd3As2 has the record-high mobility and positive linear magnetoresistance in perpendicular magnetic fields. However, the NMR has not ye...
متن کاملQuantum Paramagnet and Frustrated Quantum Criticality in a Spin-One Diamond Lattice Antiferromagnet
Motivated by the proposal of topological quantum paramagnet in the diamond lattice antiferromagnet NiRh2O4, we propose a minimal model to describe the magnetic interaction and properties of the diamond material with the spin-one local moments. Our model includes the first and second neighbor Heisenberg interactions as well as a local single-ion spin anisotropy that is allowed by the spin-one na...
متن کاملPhenomenology of a semi-Dirac semi-Weyl semimetal
We extend the semiclassical study of fermionic particle-hole symmetric semi-Dirac (more appropriately, semiDirac semi-Weyl) dispersion of quasiparticles, εK = ± √ (k2 x/2m) + (vky)) = ±ε0 √ K4 x +K2 y in dimensionless units, discovered computationally in oxide heterostructures by Pardo and collaborators. This unique system is a highly anisotropic sister phase of both (symmetric) graphene and wh...
