Cryogenic focused-ion-beam microstructuring enabling quantitative -axis transport measurements in TlBaCuO
Ayanesh Maiti, Carsten Putzke, Linus Holeschovsky +10
Absolute transport measurements in correlated quantum materials are often limited by disorder, inhomogeneity, geometric uncertainty, and small crystal size. Focused ion beam (FIB)…
Nonlinear optical diode effect in a magnetic Weyl semimetal
Christian Tzschaschel, Jian-Xiang Qiu, Xue-Jian Gao +18
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Opt…
Phenomenology of bond and flux orders in kagome metals

Superconductor/metal interfaces are usually fabricated in heterostructures that join these dissimilar materials. A conceptually different approach has recently exploited the strain…
Quasi-symmetry protected topology in a semi-metal
Chunyu Guo, Lunhui Hu, Carsten Putzke +10
The crystal symmetry of a material dictates the type of topological band structures it may host, and therefore symmetry is the guiding principle to find topological materials. Here…
Layered Metals as Polarized Transparent Conductors
