Modeling strained CdAs thin films and their behavior in magnetic fields
M. Smith, A. A. Burkov, P. P. Orth +2
We present a systematic analysis of the behavior of thin films of CdAs under different strain profiles and in magnetic fields. In each case, we construct effective $k \cdot…
Probing pairing symmetries through quasiparticle interference in chiral Bloch bands
Sayan Banerjee, Subrata Mandal, Peter P. Orth +1
Recent experiments in van der Waals multi-layer systems have demonstrated that superconductivity can emerge from symmetry-reduced, chiral normal states. We here provide a theory fo…
Symmetry tuning topological states of an axion insulator with noncollinear magnetic order
S. X. M. Riberolles, A. M. NediÄ, B. Kuthanazhi +10
Topological properties of quantum materials are intimately related to symmetry. Here, we tune the magnetic order of the axion insulator candidate EuInAs from its broken-hel…
Observation of the Axion quasiparticle in 2D MnBiTe
Jian-Xiang Qiu, Barun Ghosh, Jan Schütte-Engel +32
In 1978, Wilczek and Weinberg theoretically discovered a new boson-the Axion-which is the coherent oscillation of the field in QCD. Its existence can solve multiple fundamenta…
Spiral Spin Liquid State in the Corrugated Honeycomb Lattice of CaMnP
Farhan Islam, Nikita D. Andriushin, ThaÃs V. Trevisan +9
CaMnP exemplifies the realization of a frustrated -- Heisenberg model of a corrugated honeycomb magnetic lattice. Previous studies show that below the Néel…
