Crossover of Magnetoresistance from Fourfold to Twofold Symmetry in SmB6 Single Crystal, a topological Kondo insulator

Zengji Yue, Xiaolin Wang, Duanliang Wang +3

Topological Kondo insulators have been attracting great attention from the condensed-matter physics community due to their fascinating topological and strongly correlated propertie…

FeCrS in magnetic fields: possible evidence for a multiferroic ground state

J. Bertinshaw, C. Ulrich, A. Günther +11

We report on neutron diffraction, thermal expansion, magnetostriction, dielectric, and specific heat measurements on polycrystalline FeCr2S4 in external magnetic fields. The ferrim…

Excitonic Superfluidity and Screening in Electron-Hole Bilayer Systems

D. Neilson, A. Perali, A. R. Hamilton

Superfluidity in e-h bilayers in graphene and GaAs has been predicted many times but not observed. A key problem is how to treat the screening of the Coulomb interaction for pairin…

Phase Transition and Thermal Order-by-Disorder in the Pyrochlore Quantum Antiferromagnet Er2Ti2O7: a High-Temperature Series Expansion Study

J. Oitmaa, R. R. P. Singh, A. G. R. Day +2

Several rare earth magnetic pyrochlore materials are well modeled by a spin-1/2 quantum Hamiltonian with anisotropic exchange parameters Js. For the Er2Ti2O7 material, the Js were…

Scaling of the Kondo zero bias peak in a hole quantum dot at finite temperatures

O. Klochan, A. P. Micolich, A. R. Hamilton +5

We have measured the zero bias peak in differential conductance in a hole quantum dot. We have scaled the experimental data with applied bias and compared to real time renormalizat…

Magnetic phase diagram of

D. C. Peets, J. -H. Kim, P. Dosanjh +5

Magnetometry, electrical transport, and neutron scattering measurements were performed on single crystals of the Fe^{4+}-containing perovskite-related phase Sr_3Fe_2O_7-x as a func…
