Thermal Hall conductivity in the cuprate Mott insulators Nd2CuO4 and Sr2CuO2Cl2
What makes the phonons in cuprates become chiral, as measured by their thermal Hall effect, is an unresolved question. Here, the authors rule out two extrinsic mechanisms and argue that chirality comes from a coupling of acoustic phonons to the intrinsic

Sum rules for the optical and Hall conductivity in graphene [PDF]
Graphene has two atoms per unit cell with quasiparticles exhibiting the Dirac-like behavior. These properties lead to interband in addition to intraband optical transitions and modify the $f$-sum rule on the longitudinal conductivity. The expected dependence of the corresponding spectral weight on the applied gate voltage $V_g$ in a field effect ...

Multiple Magnetorotons and Spectral Sum Rules in Fractional Quantum Hall Systems
We study numerically the the charge neutral excitations (magnetorotons) in fractional quantum Hall systems, concentrating on the two Jain states near quarter filling, $ν=2/7$ and $ν=2/9$, and the $ν=1/4$ Fermi-liquid state itself. In contrast to the $ν=1/3$ states and the Jain states near half filling, on each of the two Jain states $ν=2/7$ and $ν=2/9$

Skew quantum Murnaghan-Nakayama rule [PDF]
In this paper, we extend recent results of Assaf and McNamara on skew Pieri rule and skew Murnaghan-Nakayama rule to a more general identity, which gives an elegant expansion of the product of a skew Schur function with a quantum power sum function in ...

Hall–Petch effect in binary and ternary alumina / zirconia / spinel composites
We present the Hall–Petch correlation between microhardness values and grain sizes for single, binary (50-50 vol.%), and ternary (33-33-33 vol.%) phase composites of yttria-stabilized zirconia (8Y–ZrO2), spinel (MgAl2O4), and alumina (Al2O3) samples ...

Sign of inverse spin Hall voltages generated by ferromagnetic resonance and temperature gradients in yttrium iron garnet|platinum bilayers [PDF]
We carried out a concerted effort to determine the absolute sign of the inverse spin Hall effect voltage generated by spin currents injected into a normal metal. We focus on yttrium iron garnet (YIG)|platinum bilayers at room temperature, generating spin

Electronic Wave-Packets in Integer Quantum Hall Edge Channels: Relaxation and Dissipative Effects
We theoretically investigate the evolution of the peak height of energy-resolved electronic wave-packets ballistically propagating along integer quantum Hall edge channels at filling factor equal to two.
