Quantum dynamics simulations beyond the coherence time on NISQ hardware by variational Trotter compression
Noah F. Berthusen, Thaís V. Trevisan, Thomas Iadecola +1
We demonstrate a post-quench dynamics simulation of a Heisenberg model on present-day IBM quantum hardware that extends beyond the coherence time of the device. This is achieved us…
Quantum Anomalous Hall Effect in Perfectly Compensated Collinear Antiferromagnetic Thin Films
Chao Lei, Olle Heinonen, R. J. McQueeney +1
We show that the quantum anomalous Hall effect almost always occurs in magnetic topological insulator thin films whenever the top and bottom surface layer magnetizations are parall…
Visualizing band selective enhancement of quasiparticle lifetime in a metallic ferromagnet
Na Hyun Jo, Yun Wu, Thaís V. Trevisan +8
Electrons navigate more easily in a background of ordered magnetic moments than around randomly oriented ones. This fundamental quantum mechanical principle is due to their Bloch w…
Bicircular light tuning of magnetic symmetry and topology in Dirac semimetal CdAs
Thaís V. Trevisan, Pablo Villar Arribi, Olle Heinonen +2
We show that Floquet engineering using bicircular light (BCL) is a versatile way to control magnetic symmetries and topology in materials. The electric field of BCL, which is a sup…
