Quantum-Hall physics and three dimensions
Johannes Gooth, Stanislaw Galeski, Tobias Meng
The discovery of the quantum Hall effect (QHE) in 1980 marked a turning point in condensed matter physics: given appropriate experimental conditions, the Hall conductivity σ_xy of…
Conformal anomaly in magnetic finite temperature response of strongly interacting one-dimensional spin systems
Christian Northe, Chunxu Zhang, Rafał Wawrzyńczak +3
The conformal anomaly indicates the breaking of conformal symmetry (angle-preserving transformations) in the quantum theory by quantum fluctuations and is a close cousin of the gra…
Application of FPGA based Lock-in amplifier for ultrasound propagation measurements using the pulse-echo technique
Stanislaw Galeski, Rafał Wawrzyńczak, Claudius Riek +1
We describe application of a state-of-the art digital FPGA based Lock-In amplifier to measurements of ultrasound propagation and attenuation at fixed frequency in low temperatures…
Bonding and Electronic Nature of the Anionic Framework in LaPdS
Tanya Berry, Michael Nicklas, Qun Yang +6
Double Dirac materials are a topological phase of matter in which a non-symmorphic symmetry enforces greater electronic degeneracy than normally expected up to eightfold. The cubic…
Engineering a pure Dirac regime in ZrTe
Jorge I. Facio, Elisabetta Nocerino, Ion Cosma Fulga +13
Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets. This tends to mask the physics of the relativistic quasiparticles.…
Topology and Chirality
Claudia Felser, Johannes Gooth
Topology, a well-established concept in mathematics, has nowadays become essential to describe condensed matter. At its core are chiral electron states on the bulk, surfaces and ed…
Signatures of a magnetic-field-induced Lifshitz transition in the ultra-quantum limit of the topological semimetal ZrTe
S. Galeski, H. F. Legg, R. Wawrzyńczak +10
The quantum limit (QL) of an electron liquid, realised at strong magnetic fields, has long been proposed to host a wealth of strongly correlated states of matter. Electronic states…
