Light-Driven Raman Coherence as a Non-Thermal Route to Ultrafast Topology Switching
C. Vaswani, L. -L. Wang, D. H. Mudiyanselage +14
A grand challenge underlies the entire field of topology-enabled quantum logic and information science: how to establish topological control principles driven by quantum coherence…
Manipulating Femtosecond Spin--Orbit Torques with Laser Pulse Sequences to Control Magnetic Memory States and Ringing
P. C. Lingos, J. Wang, I. E. Perakis
Femtosecond (fs) coherent control of collective order parameters is important for non--equilibrium phase dynamics in correlated materials. Here we propose a possible scheme for fs…
Correlating Quasi-Electron Relaxation with Quantum Femtosecond Magnetism in the Order Parameter Dynamics of Insulating Manganites
T. Li, A. Patz, P. Lingos +5
Femtosecond (fs)-resolved simultaneous measurements of charge and spin dynamics reveal the coexistence of two different quasi-particle excitations in colossal magneto-resistive (CM…
Ultrafast Dynamics of Interfacial Electric Fields in Semiconductor Heterostructures Monitored by Pump-Probe Second Harmonic Generation
Yu. D. Glinka, T. V. Shahbazyan, I. E. Perakis +4
We report first measurements of the ultrafast dynamics of interfacial electric fields in semiconductor multilayers using pump-probe second harmonic generation (SHG). A pump beam wa…
Ultrafast Spin Dynamics in GaAs/GaSb/InAs Heterostructures Probed by Second Harmonic Generation
Yu. D. Glinka, T. V. Shahbazyan, I. E. Perakis +4
We report the first application of pump-probe second harmonic generation (SHG) measurements to characterize optically-induced magnetization in non-magnetic multilayer semiconductor…
Luminescence from highly excited nanorings: Luttinger liquid description
T. V. Shahbazyan, I. E. Perakis, M. E. Raikh
We study theoretically the luminescence from quantum dots of a ring geometry. For high excitation intensities, photoexcited electrons and holes form Fermi seas. Close to the emissi…
