Holistic Parameteric Reconstruction of Building Models from Point Clouds

Kavli Affiliate: Jie Shan | First 5 Authors: Zhixin Li, Zhixin Li, , , | Summary: Building models are conventionally reconstructed by building roof points planar segmentation and then using a topology graph to group the planes together. Roof edges and vertices are then mathematically represented by intersecting segmented planes. Technically, such solution is based […]

Global inducing point variational posteriors for Bayesian neural networks and deep Gaussian processes

Kavli Affiliate: Christopher Ober| First 5 Authors: Sebastian W. Ober, Sebastian W. Ober, , , | Summary:We consider the optimal approximate posterior over the top-layer weights in a Bayesian neural network for regression, and show that it exhibits strong dependencies on the lower-layer weights. We adapt this result to develop a correlated approximate posterior over […]

Spectral and spatial isolation of single WSe$_2$ quantum emitters using hexagonal boron nitride wrinkles

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: RaphaĆ«l S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]

Nanoscale Strain Engineering of Giant Pseudo-Magnetic Fields, Valley Polarization and Topological Channels in Graphene

Kavli Affiliate: N. C. Yeh |Summary:The existence of nontrivial Berry phases associated with two inequivalent valleys in graphene provides interesting opportunities for investigating the valley-projected topological states. Examples of such studies include observation of anomalous quantum Hall effect in monolayer graphene, demonstration of topological zero modes in molecular graphene assembled by scanning tunneling microscopy, and […]

Direct growth of mm-size twisted bilayer graphene by plasma-enhanced chemical vapor deposition

Kavli Affiliate: N. C. Yeh |Summary:Plasma enhanced chemical vapor deposition (PECVD) techniques have been shown to be an efficient method to achieve single-step synthesis of high-quality monolayer graphene (MLG) without the need of active heating. Here we report PECVD-growth of single-crystalline hexagonal bilayer graphene (BLG) flakes and mm-size BLG films with the interlayer twist angle […]

Quasiparticle lifetime of the repulsive Fermi polaron

Kavli Affiliate: Nelson Darkwah Oppong| Summary:We investigate the metastable repulsive branch of a mobile impurity coupled to a degenerate Fermi gas via short-range interactions. We show that the quasiparticle lifetime of this repulsive Fermi polaron can be experimentally probed by driving Rabi oscillations between weakly and strongly interacting impurity states. Using a time-dependent variational approach, […]
