Metastable MnBiTe enabled by magnetic-field-assisted synthesis
Abhinna Rajbanshi, G. M. Zills, Alexander M. Donald +7
Magnetic topological insulators provide a unique platform to explore the interplay between magnetism and topology. MnBiTe, known for its A-type antiferromagnetic (AFM) grou…
Microwave Kerr/Faraday Resonance in Two-dimensional Chiral Superconductors
Taiki Matsushita, Jun'ichi Ieda, Yasufumi Araki +3
We investigate the polar Kerr and Faraday effects in two-dimensional multiband chiral superconductors. We show that the clapping modes--the relative phase and amplitude oscillation…
Intrinsic spin Nernst effect in spin-triplet superconductors
Taiki Matsushita, Youichi Yanase, Takeshi Mizushima +2
We theoretically investigate the intrinsic (impurity-independent) spin Nernst effect (SNE), a spin current generation perpendicular to temperature gradients, in spin-triplet superc…
Tuning Quantum States at Chirality-Reversed Planar Interface in Weyl Semimetals using an Interstitial Layer
Eklavya Thareja, Gina Pantano, Ilya Vekhter +1
The electronic band structure of Weyl semimetals possesses pairs of linear band crossings, called Weyl nodes, characterized by opposite chirality charges associated with each node.…
Trends in hot carrier distribution for disordered noble-transition metal alloys
Eklavya Thareja, Kevin M. McPeak, Phillip T. Sprunger +2
We developed and tested an approach for predicting trends for efficient hot carrier generation among disordered metal alloys. We provide a simple argument for the importance of ind…
Defect bound states in the continuum of bilayer electronic materials without symmetry protection
Daniel Massatt, Stephen P. Shipman, Ilya Vekhter +1
We analyze a class of bound defect states in the continuum electronic spectrum of bilayer materials, which emerge independent of symmetry protection or additional degrees of freedo…
Inter-quintuple layer coupling and topological phase transitions in the chalcogenide topological insulators
Karunya Shirali, William A. Shelton, Ilya Vekhter
Driving quantum phase transitions in the 3D topological insulators offers pathways to tuning the topological states and their properties. We use DFT-based calculations to systemati…
Control of magnetism in singlet-triplet superconducting heterostructures
A. Romano, P. Gentile, Canio Noce +2
We analyze the magnetization at the interface between singlet and triplet superconductors and show that its direction and dependence on the phase difference across the junction are…
Orbital order and Hund's rule frustration in Kondo lattices
L. Isaev, K. Aoyama, I. Paul +1
We analyze a microscopic origin of the Kondo effect-assisted orbital order in heavy-fermion materials. By studying the periodic two-orbital Anderson model with two local electrons,…
Ferromagnetic Quantum Critical Point in FeGa3 Tuned by Mixed-Valence Fe Dimers
N. Haldolaarachchige, J. Prestigiacomo, W. Adam Phelan +9
The magnetic, transport, and thermal properties of single crystals of the series Fe(Ga1-xGex)3 are reported. Pure FeGa3 is a nonmagnetic semiconductor, that when doped with small c…
Impurity states in multiband s-wave superconductors: analysis of iron pnictides
R. Beaird, I. Vekhter, Jian-Xin Zhu
We examine the effect of a single, non-magnetic impurity in a multiband, extended s-wave superconductor allowing for anisotropy of the gaps on the Fermi surfaces. We derive analyti…
Kondo effect in the presence of spin-orbit coupling
L. Isaev, D. F. Agterberg, I. Vekhter
We study the T=0 Kondo physics of a spin-1/2 impurity in a non-centrosymmetric metal with spin-orbit interaction. Within a simple variational approach we compute ground state prope…
Fermi surface evolution through a heavy fermion superconductor-to-antiferromagnet transition: de Haas-van Alphen effect in Cd-substituted CeCoIn
C. Capan, Y-J. Jo, L. Balicas +10
We report the results of de-Haas-van-Alphen (dHvA) measurements in Cd doped CeCoIn and LaCoIn. Cd doping is known to induce an antiferromagnetic order in the heavy fermion…
