Importance of the semimetallic state for the quantum Hall effect in HfTe
M. M. Piva, R. Wawrzyńczak, Nitesh Kumar +5
At ambient pressure, HfTe is a material at the boundary between a weak and a strong topological phase, which can be tuned by changes in its crystalline structure or by the ap…
Inelastic Neutron Scattering Study of the Spin Dynamics in the Breathing Pyrochlore System LiGa0.95In0.05Cr4O8
Yu Tanaka, Rafał Wawrzyńczak, Manh Duc Le +6
The A-site ordered chromate spinels LiGa1-xInxCr4O8 host a network of size-alternating spin-3/2 Cr3+ tetrahedra known as a 'breathing' pyrochlore lattice. For the x=0.05 compositio…
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…
Quasi-quantized Hall response in bulk InAs
Rafał Wawrzyńczak, Stanislaw Galeski, Jonathan Noky +3
The quasi-quantized Hall effect (QQHE) is the three-dimensional (3D) counterpart of the integer quantum Hall effect (QHE),exhibited only by two-dimensional (2D) electron systems. I…
Unconventional Hall response in the quantum limit of HfTe5
S. Galeski, X. Zhao, R. Wawrzyńczak +14
Interacting electrons confined to their lowest Landau level in a high magnetic field can form a variety of correlated states, some of which manifest themselves in a Hall effect. Al…
Anisotropic electrical and thermal magnetotransport in the magnetic semimetal GdPtBi
Clemens Schindler, Stanislaw Galeski, Walter Schnelle +14
The half-Heusler rare-earth intermetallic GdPtBi has recently gained attention due to peculiar magnetotransport phenomena that have been associated with the possible existence of W…
