  1. Discovery of Spin-Vortex-Crystal Magnetic Order in Ni- and Co- Doped CaKFe4As4

    20 Jun 2019 | | Contributor(s):: Paul C. Canfield

    The discovery of CaFe2As2 in 2008 revealed the extreme member of the AEFe2As2 family AE = Ba, Sr, Ca. CaFe2As2 has the smallest c-lattice parameter, manifests a strongly coupled, first-order, structural/magnetic phase transition and can be coaxed into a collapsed tetragonal phase transition,...

  2. Aharonov-Bohm Interference of Fractional Quantum Hall Edge Modes

    20 Jun 2019 | | Contributor(s):: Michael J. Manfra

    The braiding statistics of certain fractional quantum Hall states can be probed via interferometry of their edge states. Practical difficulties – including loss of phase coherence – make this a challenging task. We demonstrate the operation of a small Fabry-Perot interferometer in...

  3. International Symposium of Quantum Science & Technology

    01 Jun 2019 | | Contributor(s):: Yong P. Chen (organizer)

    This symposium will review the current status and important recent international developments in quantum science and technology, and will help chart future directions for this hot-button topic.

  4. Suppression of Exciton Condensation in Copper-Doped TiSe2

    24 May 2019 | | Contributor(s):: Melinda S. Rak

    This work establishes M-EELS as a versatile technique for studying a new class of macroscopic quantum condensates in condensed matter.

  5. Fractal Views on Quantum Materials

    08 May 2019 | | Contributor(s):: Erica W. Carlson

    Carlson will discuss how understanding the formation of these patterns is vital to our understanding of electronic properties and to our eventual technological control of quantum matter.
