Large inverted band-gap in strained three-layer InAs/GaInSb quantum wells
C. Avogadri, S. Gebert, S. S. Krishtopenko +17
Quantum spin Hall insulators (QSHIs) based on HgTe and three-layer InAs/GaSb quantum wells (QWs) have comparable bulk band-gaps of about 10--18~meV. The former however features a b…
Lorentz-boost-driven magneto-optics in a Dirac nodal-line semimetal
J. Wyzula, X. Lu, D. Santos-Cottin +13
Optical response of crystalline solids is to a large extent driven by excitations that promote electrons among individual bands. This allows one to apply optical and magneto-optica…
Kerr non-linearity in a superconducting Josephson metamaterial
Yu. Krupko, V. D. Nguyen, T. Weißl +8
We present a detailed experimental and theoretical analysis of the dispersion and non-linear Kerr frequency shifts of plasma modes in a one-dimensional Josephson junction chain con…
A tunable Josephson platform to explore many-body quantum optics in circuit-QED
Javier Puertas Martinez, Sebastien Leger, Nicolas Gheeraert +10
Coupling an isolated emitter to a single mode of the electromagnetic field is now routinely achieved and well understood. Current efforts aim to explore the coherent dynamics of em…
Field induced Lifshitz transition in UPtSi: Fermi surface under extreme conditions
D. Schulze Grachtrup, N. Steinki, S. Süllow +6
We have measured Hall effect, magnetotransport and magnetostriction on the field induced phases of single crystalline UPtSi in magnetic fields up to 60\,T at temperatures d…
Specific heat in high magnetic fields and magnetic phase diagram of CePtIn
Y. Krupko, A. Demuer, S. Ota +3
We report specific heat measurements on a high quality single crystal of the heavy-fermion compound CePtIn in magnetic fields up to 27 T. The zero-field specific heat data…
