Antiferromagnetism-altered plasmon dynamics
Yifan Su, Suheng Xu, Rocco A. Vitalone +17
The interaction between plasmons and magnons is a long-sought phenomenon with implications for fundamental physics and spintronics applications. In three-dimensional systems, this…
Quantum Light Nano-Imaging
Michael Dapolito, Matthew Fu, Fuyang Tay +20
Entanglement and quantum correlations are central to the physics of quantum materials, yet they have remained notoriously difficult to access experimentally. Accessing these phenom…
Plasmon dynamics in graphene
Suheng Xu, Birui Yang, Nishchhal Verma +15
Plasmon are collective oscillations of mobile electrons with dynamics controlled by their charge stiffness("Drude weight"). Using terahertz spacetime metrology, we probe Plasmon dy…
Space-time duality in polariton dynamics
Suheng Xu, Seunghwi Kim, Rocco A. Vitalone +13
The spatial and temporal dynamics of wave propagation are intertwined. A common manifestation of this duality emerges in the spatial and temporal decay of waves as they propagate t…
Uniaxial plasmon polaritons charge transfer at the graphene/CrSBr interface
Daniel J. Rizzo, Eric Seewald, Fangzhou Zhao +24
Graphene is a privileged 2D platform for hosting confined light-matter excitations known as surface plasmon-polaritons (SPPs), as it possesses low intrinsic losses with a high degr…
Plasmonic polarization sensing of electrostatic superlattice potentials
Shuai Zhang, Jordan Fonseca, Daniel Bennett +15
Plasmon polaritons are formed by coupling light with delocalized electrons. The half-light and half-matter nature of plasmon polaritons endows them with unparalleled tunability via…
Nano-Imaging of Landau-Phonon Polaritons in Dirac Heterostructures
Lukas Wehmeier, Suheng Xu, Rafael A. Mayer +19
Polaritons are light-matter quasiparticles that govern the optical response of quantum materials and enable their nanophotonic applications. We have studied a new type of polariton…
Electronic interactions in Dirac fluids visualized by nano-terahertz spacetime interference of electron-photon quasiparticles
Suheng Xu, Yutao Li, Rocco A. Vitalone +15
Ultraclean graphene at charge neutrality hosts a quantum critical Dirac fluid of interacting electrons and holes. Interactions profoundly affect the charge dynamics of graphene, wh…
Machine Learning for Optical Scanning Probe Nanoscopy
Xinzhong Chen, Suheng Xu, Sara Shabani +7
The ability to perform nanometer-scale optical imaging and spectroscopy is key to deciphering the low-energy effects in quantum materials, as well as vibrational fingerprints in pl…
Deep learning analysis of polaritonic waves images
Suheng Xu, Alexander S. McLeod, Xinzhong Chen +11
Deep learning (DL) is an emerging analysis tool across sciences and engineering. Encouraged by the successes of DL in revealing quantitative trends in massive imaging data, we appl…
Hybrid Machine Learning for Scanning Near-field Optical Spectroscopy
Xinzhong Chen, Ziheng Yao, Suheng Xu +11
The underlying physics behind an experimental observation often lacks a simple analytical description. This is especially the case for scanning probe microscopy techniques, where t…
Moiré Engineering of Electronic Phenomena in Correlated Oxides
Xinzhong Chen, Xiaodong Fan, Lin Li +14
Moiré engineering has recently emerged as a capable approach to control quantum phenomena in condensed matter systems. In van der Waals heterostructures, moiré patterns can be form…
