Anomalous Hall antiferromagnets
Libor Smejkal, Allan H. MacDonald, Jairo Sinova +2
The Hall effect, in which current flows perpendicular to an applied electrical bias, has played a prominent role in modern condensed matter physics over much of the subject's histo…
Large Anomalous Hall Effect in Topological Insulators Proximitized by Collinear Antiferromagnets
Chao Lei, Hua Chen, Allan H. MacDonald
CrSb is an attractive material for room-temperature antiferromagnetic spintronic applications because of its high Néel temperature 700 K and semi-metallic character. We study…
Group Convolutional Neural Networks Improve Quantum State Accuracy
Christopher Roth, Allan H. MacDonald
Neural networks are a promising tool for simulating quantum many body systems. Recently, it has been shown that neural network-based models describe quantum many body systems more…
Quantum Hall Superconductivity from Moir{é} Landau Levels
Gaurav Chaudhary, A. H. MacDonald, M. R. Norman
It has long been speculated that quasi-two-dimensional superconductivity can reappear above its semiclassical upper critical field due to Landau quantization, yet this reentrant pr…
In-plane critical magnetic fields in magic-angle twisted trilayer graphene
Wei Qin, Allan H. MacDonald
It has recently been shown that superconductivity in magic-angle twisted trilayer graphene survives to in-plane magnetic fields that are well in excess of the Pauli limit, and much…
Metamagnetism of few layer topological antiferromagnets
C. Lei, O. Heinonen, A. H. MacDonald +1
MnBiTe (MBT) is a promising antiferromagnetic topological insulator whose films provide access to novel and technologically important topological phases, including quantum…
