标题： Light Control of Triplet Pairing in Correlated Electrons with Mixed-Sign Interactions

摘要： 自旋三重态超导性是拓扑量子计算的关键平台，然而在固态材料中的实验实现和控制仍然是一个重大挑战。 为此，我们提出了一种超快光学策略，通过利用扩展的哈伯德模型中的$p$波配对不稳定性来操控自旋三重态超导性，该框架适用于过渡金属氧化物。 利用弗洛凯工程，我们证明了有效自旋交换相互作用的瞬时翻转可以在线偏振光脉冲下增强$p$波配对相关性。 此外，我们揭示了在强关联系统中这种出现的自旋三重态配对可以通过正交光脉冲选择性地切换。 这项工作为稳定和控制关联材料中的自旋三重态超导性提供了一条新途径。 显示英文摘要

摘要： Spin-triplet superconductivity is a key platform for topological quantum computing, yet its experimental realization and control in solid-state materials remain a significant challenge. For this purpose, we propose an ultrafast optical strategy to manipulate spin-triplet superconductivity by leveraging $p$-wave pairing instabilities in the extended Hubbard model, a framework applicable to transition-metal oxides. Utilizing Floquet engineering, we demonstrate that transient flipping of the effective spin-exchange interaction can enhance $p$-wave pairing correlations under linearly polarized optical pulses. Furthermore, we reveal that this emergent spin-triplet pairing in strongly correlated systems can be selectively switched by an orthogonal optical pulse. This work provides a new pathway for stabilizing and controlling spin-triplet superconductivity in correlated materials.
