○ Abstract: The study of strongly correlated systems has garnered significant attention over several decades due to their capacity to exhibit diverse phases of matter influenced by correlation and spin-orbit coupling. This diversity in phases signifies the potential for exploring novel physics, given the distinct electronic and magnetic properties inherent in each phase. This investigation delves into two specific areas concerning exotic transport phenomena within strongly correlated systems. Firstly, it addresses the emergence of inductance from spin fluctuations in strongly correlated magnets. Overcoming limitations associated with emergent inductance in spiral spin systems, this research employs spinon transport methods to ascertain high-temperature and high-frequency emergent inductance. Secondly, it examines nonreciprocal transport in the U(1) gauge theory of high-Tc cuprates, particularly in light of recent observations regarding Rashba-type spin-orbit coupling on their surface. This inquiry leads to a novel prediction for nonreciprocal transport across the whole phase diagram, utilizing the framework of the Slave-boson U(1) theory. These endeavors contribute not only to a deeper comprehension of strongly correlated systems but also offer potential practical applications.
