Symmetry of magnetic correlations in spin-triplet superconductor UTe2

Nicholas P. Butch, Sheng Ran, Shanta R. Saha +6

The temperature dependence of the low-energy magnetic excitations in the spin-triplet superconductor UTe $_{2}$ was measured via inelastic neutron scattering in the normal and superco…

A counterexample to the conjectured Planckian bound on transport

Nicholas R. Poniatowski, Tarapada Sarkar, Ricardo P. S. M. Lobo +2

It has recently been conjectured that the transport relaxation rate in metals is bounded above by the temperature of the system. In this work, we discuss the transport phenomenolog…

Absence of precursor incommensurate charge order in electronic nematic Ba0.35Sr0.65Ni2As2

John Collini, Sangjun Lee, Stella X. -L. Sun +5

Recent discoveries of charge order and electronic nematic order in the iron-based superconductors and cuprates have pointed towards the possibility of nematic and charge fluctuatio…

Multiple charge density waves and superconductivity nucleation at antiphase domain walls in the nematic pnictide Ba $_{1 - x}$ Sr $_{x}$ Ni $_{2}$ As $_{2}$

Sangjun Lee, John Collini, Stella X. -L. Sun +6

How superconductivity interacts with charge or nematic order is one of the great unresolved issues at the center of research in quantum materials. Ba $_{1 - x}$ Sr $_{x}$ Ni $_{2}$ As$_{2}…

Anomalous symmetry breaking in Weyl semimetal CeAlGe

H. Hodovanets, C. J. Eckberg, Y. Eo +7

CeAlGe, a proposed type-II Weyl semimetal, orders antiferromagnetically below 5 K. At 2 K, spin-flop and a spin-flip transitions to less than 1 $μ_{B}$ /Ce are observed in the $M (H)$ …

Bulk transport paths through defects in floating zone and Al flux grown SmB $_{6}$

Yun Suk Eo, Alexa Rakoski, Shriya Sinha +16

We investigate the roles of disorder on low-temperature transport in SmB $_{6}$ crystals grown by both the Al flux and floating zone methods. We used the inverted resistance method wi…

Topologically-Driven Linear Magnetoresistance in Helimagnetic FeP

D. J. Campbell, J. Collini, J. Slawinska +11

The helimagnet FeP is part of a family of binary pnictide materials with the MnP-type structure which share a nonsymmorphic crystal symmetry that preserves generic band structure c…

Resistivity saturation in an electron-doped cuprate

Nicholas R. Poniatowski, Tarapada Sarkar, Sankar Das Sarma +1

We report the observation of resistivity saturation in lightly doped ( $x \sim 0.10)$ as-grown samples of the electron-doped cuprate La $_{2 - x}$ Ce $_{x}$ CuO $_{4}$ (LCCO). The saturation oc…

Quantum-critical scale invariance in a transition metal alloy

Y. Nakajima, T. Metz, C. Eckberg +14

Quantum-mechanical fluctuations between competing phases at $T = 0$ induce exotic finite-temperature collective excitations that are not described by the standard Landau Fermi liquid…
