Spin-Orbit-Mediated Magnetization Transfer in the Fermi-Hubbard Model
Jialiang Tang, Ruoqian Xu, Gloria Platero +2
We demonstrate spin--orbit-coupling (SOC) catalysis of magnetization-sector transfer in the half-filled Fermi--Hubbard model. Without SOC, conservation of total magnetization confi…

Sebastián V. Romero, Xi Chen, Yue Ban
Recent advances in quantum information and quantum thermodynamics have reshaped the understanding of energy storage at the microscopic scale, paving the way toward protocols for st…
Weighted Nested Commutators for Scalable Counterdiabatic State Preparation
Jialiang Tang, Xi Chen, Zhi-Yuan Wei
Counterdiabatic (CD) driving enables efficient quantum state preparation, but it requires implementing highly nonlocal adiabatic gauge potentials (AGP) that are impractical to comp…
