Odd-parity superconductivity underpinned by antiferromagnetism in heavy fermion metal YbRhSi
Lev V. Levitin, Jan Knapp, Petra Knappová +13
Topological superconductors are essential elements of the periodic table of topological quantum matter. However, the relevant odd-parity spin-triplet superconductors are rare. We r…
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…
Precise Calorimetry of Small Metal Samples Using Noise Thermometry
Jan Knapp, Lev V. Levitin, Ján Nyéki +2
We describe a compact calorimeter that opens ultra-low temperature heat capacity studies of small metal crystals in moderate magnetic fields. The performance is demonstrated on the…
Spiral Spin Liquid Noise
Hiroto Takahashi, Chun-Chih Hsu, Fabian Jerzembeck +10
An emerging concept for identification of different types of spin liquids is through the use of spontaneous spin noise. Here we develop spin noise spectroscopy for spin liquid stud…
