Nonsymmorphic Symmetry-Protected Band Crossings in a Square-Net Metal PtPb
Han Wu, Alannah M. Hallas, Xiaochan Cai +15
Topological semimetals with symmetry-protected band crossings have emerged as a rich landscape to explore intriguing electronic phenomena. Nonsymmorphic symmetries in particular ha…
Field-induced quantum critical point in the new itinerant antiferromagnet TiCu
Jaime M. Moya, Alannah M. Hallas, Vaideesh Loganathan +13
New phases of matter emerge at the edge of magnetic instabilities. In local moment systems, such as heavy fermions, the magnetism can be destabilized by pressure, chemical doping,…
Noncollinear Antiferromagnetic Order and Effect of Spin-Orbit Coupling in Spin-1 Honeycomb Lattice
Shuyi Li, Manh Duc Le, Vaideesh Loganathan +1
Motivated by the recently synthesized insulating nickelate NiMoO, which has been reported to have an unusual non-collinear magnetic order of Ni moments wit…
Anomalous metamagnetism in the low carrier density Kondo lattice YbRh3Si7
Binod K. Rai, S. Chikara, Xiaxin Ding +25
We report complex metamagnetic transitions in single crystals of the new low carrier Kondo antiferromagnet YbRh3Si7. Electrical transport, magnetization, and specific heat measurem…
From Half-metal to Semiconductor: Electron-correlation Effects in Zigzag SiC Nanoribbons From First Principles
Naresh Alaal, Vaideesh Loganathan, Nikhil Medhekar +1
We performed electronic structure calculations based on the first-principles many-body theory approach in order to study quasiparticle band gaps, and optical absorption spectra of…
Large magnetic anisotropy in Fe_{0.25}TaS_2
Vaideesh Loganathan, Jian-Xin Zhu, Andriy H. Nevidomskyy
We present a first-principles study of the large magneto-crystalline anisotropy in the intercalated di-chalcogenide material \ce{Fe_{0.25}TaS_2}, investigated with the DFT+U approa…
First principles many-body calculations of electronic structure and optical properties of SiC nanoribbons
Naresh Alaal, Vaideesh Loganathan, Nikhil Medhekar +1
A first principles many-body approach is employed to calculate the band structure and optical response of nanometer sized ribbons of SiC. Many-body effects are incorporated using t…
