RE-ENTRANT CORRELATED INSULATOR AT 2π MAGNETIC FLUX IN MAGIC-ANGLE TWISTED BILAYER GRAPHENE
Ipsita Das, Dmitri K. Efetov, ICFO Spain and Benjamin A. Piot, LNCMI Grenoble. Different interacting phases such as correlated insulators, superconductors, magnetic states, Chern insulators, strange metals, anomalous quantum Hall effect etc. have been extensively studied in the flat band [...]
LIQUID-RUBIDIUM ALFVÉN-WAVE EXPERIMENT IN PULSED MAGNETIC FIELDS
Frank Stefani und Thomas Herrmannsdörfer, HZDR and HLD Dresden. The heating of the Sun‘s corona to temperatures of several million kelvin is one of the major unsolved problems of solar physics. Although magnetic fields are unambiguously considered responsible for the [...]
MAGNETIC RESHUFFLING AND FEEDBACK ON SUPERCONDUCTIVITY IN UTe2 UNDER PRESSURE
Michal Vališka, CEA-Grenoble and Charles University Prague, William Knafo, LNCMI Toulouse and Daniel Braithwaite, CEA-Grenoble. The discovery of superconductivity in the heavy-fermion paramagnet UTe2 has attracted a lot of attention, particularly due to the reinforcement of superconductivity near quantum phase [...]
QUANTUM OSCILLATIONS IN A 5d-OXIDE INTERFACE
Km Rubi and Uli Zeitler, HFML Nijmegen and Walter Escoffier, LNCMI Toulouse. A team of researchers from HFML-Nijmegen, LNCMI-Toulouse, and the National University of Singapore investigated the electronic properties of the quasi two-dimensional electron gas (2DEG) at a new 5d-oxide [...]
SPATIALLY RESOLVED OPTICAL SPECTROSCOPY IN AN EXTREME ENVIRONMENT OF LOW TEMPERATURE, HIGH MAGNETIC FIELDS, AND HIGH PRESSURE
Ivan Breslavetz and Clément Faugeras, LNCMI Grenoble. To flesh out the phase diagrams of novel material systems, researchers must examine these materials under extreme conditions. We have designed an experimental setup for optical spectroscopy that simultaneously offers three extremes: low [...]

Paragraf™ has leveraged its expertise in the manufacturing & implementation of graphene technology to make another major advance in Hall-sensor performance. The company has announced the availability of a new sensor range capable of unmatched sensitivity and linearity when placed [...]
LARGE LINEAR NON-SATURATING MAGNETORESISTANCE AND HIGH MOBILITY IN FERROMAGNETIC MnBi
Toni Helm, HLD Dresden. Currently, a group of semimetals excites the physics community due to its intriguing properties derived from massless chiral particles— so-called Weyl fermions. As a consequence of linear band crossings at the Fermi energy and a high [...]
SIGNATURES OF INCOHERENT TRANSPORT IN THE STRANGE-METAL REGIME OF HIGH-TC CUPRATES
Jake Ayres, University of Bristol, Maarten Berben and Nigel Hussey, HFML Nijmegen. Researchers from HFML-EMFL, UK, Netherlands, and Japan studied the high-field magnetotransport properties of overdoped high-Tc cuprates and found behavior that is strikingly different from that of ordinary metals. [...]
RYDBERG SERIES OF DARK EXCITONS AND THE CONDUCTION BAND SPIN-ORBIT SPLITTING IN MONOLAYER WSe2
Piotr Kapuściński and Marek Potemski, LNCMI Grenoble. Strong Coulomb correlations together with multi-valley electronic bands in the presence of spin-orbit interaction are at the heart of studies of the rich physics of excitons in semiconductor structures made of monolayers of [...]
ORIGIN OF THE QUASI-QUANTIZED HALL EFFECT IN ZrTe5
Stanislaw Galeski, MPI CPfS Dresden and Sergei Zherlitsyn, HLD Dresden. The quantum Hall effect (QHE) is traditionally considered to be a purely two-dimensional (2D) phenomenon. Recently, however, a three-dimensional (3D) version of the QHE was reported in the Dirac semimetal [...]
