Linear magneto-conductivity as a DC probe of time-reversal symmetry breaking
Veronika Sunko, Chunxiao Liu, Marc Vila +6
Several optical experiments have shown that in magnetic materials the principal axes of response tensors can rotate in a magnetic field. Here we offer a microscopic explanation of…
Terahertz time-domain spectroscopy of transient metallic and superconducting states
J. Orenstein, J. S. Dodge
Time-resolved terahertz time-domain spectroscopy (THz-TDS) is an ideal tool for probing photoinduced nonequilibrium metallic and superconducting states. Here, we focus on the inter…
Berry phase mechanism for optical gyrotropy in stripe-ordered cuprates
J. Orenstein, Joel E. Moore
Optical gyrotropy, the lifting of degeneracy between left and right circularly polarized light, can be generated by either time-reversal or chiral symmetry breaking. In the high-$T…
Observation of Coherent Helimagnons and Gilbert damping in an Itinerant Magnet
J. D. Koralek, D. Meier, J. P. Hinton +7
We study the magnetic excitations of itinerant helimagnets by applying time-resolved optical spectroscopy to Fe0.8Co0.2Si. Optically excited oscillations of the magnetization in th…
Measurement of electron-hole friction in an n-doped GaAs/AlGaAs quantum well using optical transient grating spectroscopy
Luyi Yang, J. D. Koralek, J. Orenstein +3
We use phase-resolved transient grating spectroscopy to measure the drift and diffusion of electron-hole density waves in a semiconductor quantum well. The unique aspects of this o…
Optical non-reciprocity in magnetic structures related to high-Tc superconductors
J. Orenstein
Recent neutron scattering [1,2], and optical measurements [3,4] have detected evidence in underdoped cuprate superconductors for a phase transition near the pseudogap onset tempera…
