Controlling coherent energy flow between collective THz excitations in condensed matter
Optics InfoBase Conference Papers (2014)
Abstract:
Coherent control over the magnetization state of the rare-earth orthoferrite ErFeO3 is achieved by nonlinear lattice excitation via mid-infrared laser pulses. This low-dissipative approach enables new pathways in light-driven manipulation of magnetic materials. © 2014 OSA.Femtosecond time-and-angle-resolved EUV photoemission spectroscopy with mid-IR pumping
Optics InfoBase Conference Papers (2014)
Abstract:
Time- and angle-resolved photoemission spectroscopy directly enables observation of electron dynamics in condensed matter. Using EUV high harmonic probe extends the observation window in energy and momentum. Tunable mid-infrared pumping allows control of excitation mechanisms. © 2014 OSA.Femtosecond time-and-angle-resolved EUV photoemission spectroscopy with mid-IR pumping

Optics InfoBase Conference Papers (2014)
Abstract:
We use femtosecond Resonant Soft X-ray Diffraction to observe heterogeneous melting of antiferromagnetic order in an epitaxially grown NdNiO3 film. Cross-interface coupling launches a propagating phase front following direct lattice excitation of the LaAlO3 substrate. © 2014 OSA.Mid-IR pump, EUV probe femtosecond time-and-angle- resolved photoemission spectroscopy
