EXPERIMENTAL OBSERVATION OF BETHE STRINGS
Zhe Wang, HZDR Dresden and A. Loidl, University of Augsburg. In his seminal work entitled “Eigenwerte und Eigenfunktionen der linearen Atomkette” (eigenvalues and eigenfunctions of a linear chain of [...]
HIGH-FIELD CHARGE ORDER ACROSS THE PHASE DIAGRAM OF YBCO
F. Laliberté, M. Frachet, S. Benhabib, B. Borgnic, C. Proust, D. LeBoeuf, LNCMI-Toulouse. In hole-doped cuprates there is now compelling evidence that inside the pseudogap phase, a charge density [...]
GATE-TUNING ACROSS THE SUPERCONDUCTING DOME OF MONOLAYER WS2
J. Lu, Peking University and J. Ye, University of Groningen and I. Leermakers, N. Hussey, U. Zeitler, HFML-Nijmegen. Compared with three-dimensional superconductors, atomically thin superconductors are expected to be [...]
HOW CHARGE ORDER WEAKENS SUPERCONDUCTIVITY IN YBa2Cu3Oy
Marc-Henri Julien, LNCMI Grenoble. The upper critical field, Hc2, is a fundamental, and technologically important property that measures the ability of a superconductor to withstand magnetic fields. Recently, there [...]
A MULTICALORIC COOLING CYCLE THAT EXPLOITS THERMAL HYSTERESIS
T. Gottschall, HLD Dresden. The giant magnetocaloric effect, in which large thermal changes are induced in a material on the application of a magnetic field, can be used for [...]
40-TESLA PULSED MAGNET FOR NEUTRON DIFFRACTION
A 40-T pulsed magnet for single crystal elastic neutron scattering, featuring an unprecedented high duty cycle, now offers new opportunities to investigate magnetic systems down to 2 K at the Institut Laue Langevin (ILL) in Grenoble (France).
FARADAY BALANCE MAGNETOMETER AT LNCMI-G
Gabriel Seyfarth, LNCMI Grenoble. A new Faraday-balance magnetometer for low temperatures and high magnetic fields has been developed at LNCMI Grenoble. It has been designed to probe the sample magnetization. The determination of absolute values is possible via separate calibration measurements.
AN ULTRA-COMPACT LOW-TEMPERATURE SCANNING PROBE MICROSCOPE FOR MAGNETIC FIELDS ABOVE 30 T
Lisa Rossi, Lijnis Nelemans, Ben Bryant, HFML Nijmegen. Together with technicians and scientists from HFML Nijmegen, PhD student Lisa Rossi designed and built a scanning probe microscope (SPM) for operation at cryogenic temperatures in extremely high magnetic fields. It is the only one in the world that can measure in fields above 30 Tesla.
STRONG INTERACTION EFFECTS IN MoS2 LANDAU LEVELS
Jiangxiazi Lin, Ning Wang, Hong Kong University of Science and Technology and Benjamin Piot, LNCMI-Grenoble. Semiconducting two-dimensional transition-metal dichalcogenides (TMDCs) have been a recent hot research topic in physics, for their novel optical/electronic properties and potential applications.
A DROSOPHILA FOR WEYL PHYSICS: GdPtBi
C. Shekhar, MPI CPfS Dresden and Y. Skourski, HLD Dresden. In 1929, Hermann Weyl discovered that massless spin-1/2 particles are solutions of the Dirac equation. After many decades, these Weyl particles were finally experimentally revealed in 2015 in simple semimetallic materials such as TaAs. Weyl fermions are low-energy quasiparticle excitations in the vicinity of the unavoidable touching points of a valence band and a conduction band: these materials are “Weyl semimetals”.
