Quantum Process Tomography of a Thermal Alkali-Metal Vapor
Yujie Sun, Marek Kopciuch, Arash Dezhang Fard +1
Characterizing the open-system dynamics of multilevel quantum systems (qudits) remains a fundamental challenge due to ensemble inhomogeneities and complex environmental interaction…
Ambient-pressure superconductivity onset above 40 K in bilayer nickelate ultrathin films
Guangdi Zhou, Wei Lv, Heng Wang +8
The discovery of bilayer nickelate superconductors under high pressure has opened a new chapter in high-transition temperature (high-TC) superconductivity. Here, we report ambient-…
Isolating Pure Quadratic Zeeman Splitting
Arash Dezhang Fard, Marek Kopciuch, Yujie Sun +2
Nonlinear magnetic interactions provide access to complex quantum spin dynamics and thus enable the study of intriguing physical phenomena. However, these interactions are often do…
Orbital-selective effect of spin reorientation on the Dirac fermions in a non-charge-ordered kagome ferromagnet FeGe
Rui Lou, Liqin Zhou, Wenhua Song +13
Kagome magnets provide a fascinating platform for the realization of correlated topological quantum phases under various magnetic ground states. However, the effect of the magnetic…
