Title of Talk


This seminar covers high-frequency, mechanical and/or quanum spectroscopy of magnetism in solid state physics.

All topics have substantial overlap with magnetism and nano-mechanics -related research activities at the Walther-Meissner-Institut and TUM physics department.

Topics for seminar talks in WS 2018/19:
  • Paramagnetic Spins in Solid State Systems
    1. Pulse sequences in EPR (Hahn Echo Sequences, CPMG, XYXY, ...) Magnetic resonance techniques - pulsed and cw electron spin resonance and ferromagnetic resonance
    2. 2. Sigillito, A. J. et al. Fast, low-power manipulation of spin ensembles in superconducting microresonators. Appl Phys Lett 104, 222407 (2014). (Adiabatically shaped pulses)
  • Spin Squeezing
    1. Quantum Spin Squeezing (Ma, J., Wang, X., Sun, C. P. & Nori, F., Physics Reports 509, 89–165 (2011).
    2. Squeezing the collective spin of a dilute atomic ensemble by cavity feedback (Schleier-Smith, M. H., Leroux, I. D. & Vuletić, V.,. Phys Rev A 81, 021804 (2010))
  • Magnon-Mechanics
    1. Cavity magnomechanics (Zhang, X., Zou, C.-L., Jiang, L. & Tang, H. X., Science Advances 2, e1501286–e1501286 (2016))
    2. Coupled spin-light dynamics in cavity optomagnonics (Viola Kusminskiy, S., Tang, H. X. & Marquardt, F., Phys Rev A 94, 033821 (2016))
  • Parametric Amplification & Squeezing
    1. Development of a Josephson Parametric Amplifier for the Preparation and Detection of Nonclassical States of Microwave Fields.(Castellanos-Beltran, PhD Thesis, University of Colorado, 2010)
    2. Intermodulation in microresonators (Tholén, E., PhD Thesis, KTH School of Engineering Sciences, )
  • NV centers in diamond
    1. Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction, (Dovzhenko et al., Nature Communications 9, 2712 (2018))
    2. Spatially resolved detection of complex ferromagnetic dynamics using optically detected nitrogen-vacancy spins (Wolfe et al., Applied. Phys. Letters. 108, 232409 (2016))
    3. Nanometre-scale probing of spin waves using single electron spins (T. van der Sar et al., Nature Communications 6, 7886 (2015))
