“…SRO thin films were epitaxially grown on TiO 2 -terminated SrTiO 3 (001) [STO(001)] substrates via pulsed laser deposition (34). The substrate temperature and laser repetition rate were optimized and set to 700 o C and 2 Hz, respectively (See procedural details in the Materials and Methods section).…”

“…Nevertheless, in strongly-correlated electronic systems, it is well-known that coupling between spin, charge, lattice, and orbital degrees of freedom facilitates competing ground states and thus microscopic phase segregation (12,13). Recent works on quantum anomalous Hall systems and non-collinear antiferromagnetic insulators further indicate that spatial inhomogeneities, such as magnetic domain structures and domain walls, can be important in understanding the physical properties of topological systems with considerable el-el correlation (14,15).…”

“…In SRO epitaxial heterostructures hosting a fine balance between el-el correlation and SOC, interfacial inversion-symmetry-breaking can activate the Dzyaloshinskii-Moriya interaction (DMI). As a consequence, magnetic skyrmions and chiral magnetic domains can be stabilized and embedded in a ferromagnetic matrix (32)(33)(34)(35)(36). The resultant inhomogeneity in real-space Berry curvature inevitably induces a superposition of THE and AHE signals ( Fig.…”

“…The resultant inhomogeneity in real-space Berry curvature inevitably induces a superposition of THE and AHE signals ( Fig. 1, A (32)(33)(34)(35). Soon after the discoveries of THE in SRO heterostructures, an alternative interpretation based on spatial inhomogeneity in AHE and k-space Berry curvature was proposed (37)(38)(39).…”

In quantum matters hosting electron-electron correlation and spin-orbit coupling, spatial inhomogeneities, arising from competing ground states, can be essential for determining and understanding topological properties. A prominent example is Hall anomalies observed in SrRuO 3 films, which were interpreted in terms of either magnetic skyrmion-induced topological Hall effect (THE) or inhomogeneous anomalous Hall effect (AHE). To clarify this ambiguity, we systematically investigated the AHE of SrRuO 3 ultrathin films with controllable inhomogeneities in film thickness (t SRO ). By harnessing the step-flow growth of SrRuO 3 films, we induced microscopically-ordered stripes with oneunit-cell differences in t SRO . The resultant spatial distribution of momentum-space Berry curvatures enables a two-channel AHE, which shows hump-like anomalies similar to the THE and can be continuously engineered via sub-unit-cell control of t SRO . In these inhomogeneous SRO films, we microscopically identified a two-step magnetic switching and stripe-like ferromagnetic domains. These features are fingerprints for distinguishing the two-channel AHE from the skyrmion-induced THE.

Dynamical heterogeneity (DH) in non-equilibrium systems is a topic of profound interest yet an open question. In a model system of constantly driven oppositely charged binary colloidal suspension, we explore DH in a model lane-forming system using BD simulations. We show that the system undergoes structural and dynamical cross-over using spatio-temporal correlation functions. For small field, the structural relaxation is homogeneous while it is heterogeneous for sufficiently high field. In order to explore the heterogeneity, we track and tag the particles to compute partial structures that relax at different rates, in which heterogeneity has its maximum in the intermediate state.
