How to Measure and Model Light-Induced Spin Transfer
Sinéad A. Ryan, Mohamed F. Elhanoty, Anya Grafov +13
Femtosecond laser light can transfer spin angular momentum between magnetic subspecies that exhibit hybridized valence bands within an alloy or compound, and represents the fastest…
Non-equilibrium States and Interactions in the Topological Insulator and Topological Crystalline Insulator Phases of NaCd4As3
Tika R Kafle, Yingchao Zhang, Yi-yan Wang +12
Topological materials are of great interest because they can support metallic edge or surface states that are robust against perturbations, with the potential for technological app…
Uncovering the Timescales of Spin Reorientation in
Sinéad A. Ryan, Anya Grafov, Na Li +8
Kagome ferrimagnets are of fundamental interest because of their tunable magnetic, electronic and topological properties, with potential applications for quantum-enabled technologi…
Optically controlling the competition between spin flips and intersite spin transfer in a Heusler half-metal on sub-100 fs timescales
Sinéad A. Ryan, Peter C. Johnsen, Mohamed F. Elhanoty +10
The direct manipulation of spins via light may provide a path toward ultrafast energy-efficient devices. However, distinguishing the microscopic processes that can occur during ult…
Thermal transport from 1D- and 2D-confined nanostructures on silicon probed using coherent extreme UV light: General and predictive model yields new understanding
Albert Beardo, Joshua L. Knobloch, Lluc Sendra +9
Heat management is crucial in the design of nanoscale devices as the operating temperature determines their efficiency and lifetime. Past experimental and theoretical works explori…
Creation of a novel inverted charge density wave state
Yingchao Zhang, Xun Shi, Mengxue Guan +10
Charge density wave (CDW) order is an emergent quantum phase that is characterized by a periodic lattice distortion and charge density modulation, often present near superconductin…
