Magnetic Phase Diagram of YbRh\textsubscript{2}Si\textsubscript{2}: the Influence of Hyperfine Interactions
Jan Knapp, Lev V. Levitin, Jan Nyeki +6
We report the determination of the magnetic phase diagram of the heavy fermion metal YbRh\textsubscript{2}Si\textsubscript{2} in magnetic fields up to 70\,mT applied perpendicular…
Diverse influences of hyperfine interactions on strongly correlated electron states
Femke Bangma, Lev Levitin, Marijn Lucas +8
The motivation to develop materials for quantum technologies has put exploration of novel quantum states of matter at the focus of several research fields, with particular efforts…
Cooling low-dimensional electron systems into the microkelvin regime
Lev V. Levitin, Harriet van der Vliet, Terje Theisen +10
Two-dimensional electron gases (2DEGs) with high mobility, engineered in semiconductor heterostructures host a variety of ordered phases arising from strong correlations, which eme…
Superconducting Sweet-Spot in Microcrystalline Graphite Revealed by Point-Contact Spectroscopy
Frank Arnold, Jan Nyeki, John Saunders
In this letter we describe the observation of a magnetic field dependent electronic gap, suggestive of local superconductivity, in the point-contact spectrum of micro-crystalline g…
Current Sensing Noise Thermometry: A fast practical solution to low temperature measurement
Andrew Casey, Frank Arnold, Lev V. Levitin +9
We describe the design and performance of a series of fast, precise current sensing noise thermometers. The thermometers have been fabricated with a range of resistances from 1.290…
Frequency Dependence of the Supersolid Signature in Polycrystalline 4He
George Nichols, Malcolm Poole, Jan Nyeki +2
We report studies, using a two mode torsional oscillator, of the putative supersolid signature in polycrystalline 4He. Measurements at two frequencies enable us to eliminate the vi…
