Visualizing 1D zigzag Wigner crystallization at domain walls in the Mott insulator TaS
Anuva Aishwarya, Sean Howard, Bikash Padhi +4
In a certain regime of low carrier densities and strong correlations, electrons can crystallize into a periodic arrangement of charge known as Wigner crystal. Such phases are parti…
Observation of linearly dispersive edge modes in a magnetic Weyl semimetal Co3Sn2S2
Sean Howard, Lin Jiao, Zhenyu Wang +5
The physical realization of Chern insulators is of fundamental and practical interest, as they are predicted to host the quantum anomalous Hall effect (QAHE) and topologically prot…
Observation of a Smoothly Tunable Dirac Point in
Sean Howard, Arjun Raghavan, Davide Iaia +9
State-of-the-art topological devices require the use topological surface states to drive electronic transport. In this study, we examine a tunable topological system, $Ge(Bi_{x}Sb_…
Automated data validation: an industrial experience report
Lei Zhang, Sean Howard, Tom Montpool +3
There has been a massive explosion of data generated by customers and retained by companies in the last decade. However, there is a significant mismatch between the increasing volu…
Microscopic evidence for a chiral superconducting order parameter in the heavy fermion superconductor UTe2
Lin Jiao, Sean Howard, Sheng Ran +6
Spin-triplet superconductivity is a condensate of electron pairs with spin-1 and an odd-parity wavefunction. A particularly interesting manifestation of triplet pairing is a chiral…
Signature of Dispersing 1D Majorana Channels in an Iron-based Superconductor
Zhenyu Wang, Jorge Olivares Rodriguez, Lin Jiao +6
The possible realization of Majorana fermions as quasiparticle excitations in condensed matter physics has created much excitement. Most recent studies have focused on Majorana bou…
