Spin-Lattice Dynamics and Interactions in Magnonic Spinels
Hari Paudyal, Yuri Suzuki, Michael E. Flatté +1
Minimizing magnetic damping while understanding spin-lattice interactions remains a key challenge for magnonics. We show site-specific Al/Li ordering in spinel ferrites drives a fe…
Coherent antiferromagnetic resonance in MnO driven by impulsive terahertz excitation
Yinchuan Lv, Martin J. Cross, Hari Paudyal +4
Antiferromagnets (AFMs) offer a promising platform for ultrafast information processing owing to their intrinsically fast spin dynamics and vanishing net magnetization. Realizing t…
Origin of High-Temperature Antiferromagnetic Order in a van der Waals Material
Rabindra Basnet, Hari Paudyal, Gicela Saucedo Salas +3
While Van der Waals (vdW) itinerant antiferromagnets with high Neel temperatures (TN) are highly desirable for spintronics, they remain relatively scarce. Here, we unravel the phys…
Broken site symmetry of Fe adatoms on BiTe
Duy Nguyen, Hari Paudyal, Joseph R. Sink +2
We report a combined scanning tunneling microscopy and atomistic theoretical study of Fe adatoms on the BiTe(111) surface. Topographic imaging at ~K shows that Fe adat…
Kinetics of electron-phonon scattering in silicon resolved by Rydberg transitions of donors
Nils Dessmann, Aidan G. McConnell, Sergey G. Pavlov +6
Rydberg states of atoms in vacuum are now well recognized as a resource for quantum technologies. Donors in semiconductors also display analogous states, which have been proposed f…
Ultrafast Light-Induced Magnetoelectric Effect in van der Waals Magnetic Semiconductor Heterostructures
Wenyi Zhou, Ravi Kumar Bandapelli, Hari Paudyal +8
Atomic-scale heterostructures of van der Waals (vdW) magnets and semiconductors provide a unique environment for exploring magnetic dynamics. In contrast to typical photothermal ex…
Suppression of charge-density wave and superconductivity in a lithiated NbSe monolayer
Hari Paudyal, Michael E. Flatté
We present an \textit{ab initio} investigation of the long-range charge density wave (CDW) order and superconducting properties of the pristine and lithiated NbSe monolayer. St…
Microscopic Scattering Approach to In-Gap States: Cr Adatoms on Superconducting β-Bi2Pd
Joseph Sink, Hari Paudyal, Divya Jyoti +4
We develop a microscopic scattering formalism to describe Yu-Shiba-Rusinov (YSR) states due to a single Cr adatom on the Bi-terminated surface of , by combining ab initio…
Intrinsic Berry phase contribution to Hall conductivity in CoS
Tamal Kumar Dalui, Hari Paudyal, Durga Paudyal +1
In Weyl semi-metals, the conduction and valence bands intersect at distinct points on the Brillouin zone (Weyl points), which act as monopoles of Berry curvature in momentum space.…
Functionalized CrC MXenes: Novel Magnetic Semiconductors
Yogendra Limbu, Hari Paudyal, Eudes Gomes da Silva +3
We report an \textit{ab initio} investigation of functionalized and 3-electrons doped CrC MXenes. Upon functionalization, the CrC becomes chemically, dynamically, and me…
Stability, electronic quantum states, and magnetic interactions of Er ions in GaO
Yogendra Limbu, Hari Paudyal, Michael E. Flatté +1
The chemical, structural, mechanical, and dynamical stabilities of the - and -GaO are confirmed from respective negative formation energies, negative cohesive energie…
Singly occupied 4 antiferromagnetic insulators: CePO and CeVO
Hari Paudyal, Yogendra Limbu, Michael E. Flatté +1
Rare-earth containing wide band gap oxides, which provide spin-photon interface and narrow linewidth optical emission, are getting significant attention as the most promising candi…
Implications of the electron-phonon coupling in CuPb(PO)O for superconductivity: an \textit{ab initio} study
Hari Paudyal, Michael E. Flatté, Durga Paudyal
We report calculations of the electronic and vibrational properties in CuPb(PO)O, including the electron-phonon coupling strength via strong-coupling Migdal…
