Entanglement dynamics of multi-fluxonium-qubits under Non-Markovian TLS noise
Chenghong Ji, Chaoying Zhao
The research on open quantum systems is important for both quantum computing and quantum sensing. So far, we can only use the main equation to make an approximate description. The…
Imaging magnetic flux trapping in lanthanum hydride using diamond quantum sensors
Yang Chen, Junyan Wen, Ze-Xu He +7
Lanthanum hydride has attracted significant attention in recent years due to its signatures of superconductivity at around 250 K (1, 2). However, the megabar pressures required for…
Piezomagnetism-driven magnetoelectric coupling in altermagnetic multiferroic K3Cr2F7
Ying Zhou, Hui-Min Zhang, Cheng-Ao Ji +4
Ferroelectric control of altermagnetism in momentum space has been studied widely, while the control of magnetism in real space of altermagnets are still rare. We present a design…
Out-of-plane ferroelectricity, magnetoelectric coupling and persistent spin texture in two-dimensional multiferroics
Ying Zhou, Cheng-Ao Ji, Shuai Dong +1
Two dimensional multiferroics with out of plane ferroelectricity hold significant promise for miniaturized magnetoelectric spin-orbit transistors, yet systems combining robust ferr…
