Coherent and Dynamic Small Polaron Delocalization in CuFeO$_2$

Kavli Affiliate: Naomi Ginsberg | Summary:Small polarons remain a significant bottleneck in the realization of efficient devices using transition metal oxides. Routes to engineer small polaron coupling to electronic states and lattice modes to control carrier localization remain unclear. Here, we measure the formation of small polarons in CuFeO$_2$ using transient extreme ultraviolet reflection spectroscopy […]

Engineering phase-frustration induced flat bands in an aza-triangulene covalent Kagome lattice

Kavli Affiliate: Felix Fischer | Summary:Pi-conjugated covalent organic frameworks (COFs) provide a versatile platform for the realization of designer quantum nanomaterials. Strong electron-electron correlation within these artificial lattices can give rise to exotic phases of matter. Their experimental realization however requires precise control over orbital symmetry, charge localization, and band dispersion all arising from the […]

Quantum Synchronization of Perturbed Oscillating Coherences

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yi J. Zhao, Yi J. Zhao, , , | Summary: Synchronization in quantum systems has been recently studied through persistent oscillations of local observables, which stem from undamped modes of the dissipative dynamics. However, the existence of such modes requires fine-tuning the system to satisfy specific […]

Quantum Synchronization of Perturbed Oscillating Coherences

Kavli Affiliate: Joel Moore | Summary:Synchronization in quantum systems has been recently studied through persistent oscillations of local observables, which stem from undamped modes of the dissipative dynamics. However, the existence of such modes requires fine-tuning the system to satisfy specific symmetry constraints. We investigate the response of spin systems that possess such oscillating modes […]
