Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Matthew Fisher, Michaël Gharbi, Kayvon Fatahalian, | Summary: Human pose is a useful feature for fine-grained sports action understanding. However, pose estimators are often unreliable when run on sports video due to domain shift and factors such as motion blur and occlusions. This leads to […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Matthew P. A. Fisher, , , | Summary: We explore a class of "open" quantum circuit models with local decoherence ("noise") and local projective measurements, each respecting a global Z_2 symmetry. The model supports a spin glass phase where the Z_2 symmetry is […]

Kavli Affiliate: Matthew Fisher | First 5 Authors: Sanjeev Muralikrishnan, Siddhartha Chaudhuri, Noam Aigerman, Vladimir Kim, Matthew Fisher | Summary: We investigate the problem of training generative models on a very sparse collection of 3D models. We use geometrically motivated energies to augment and thus boost a sparse collection of example (training) models. We analyze […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Zhi-Cheng Yang, Yaodong Li, Matthew P. A. Fisher, Xiao Chen, | Summary: We explore a class of random tensor network models with “stabilizer” local tensors which we name Random Stabilizer Tensor Networks (RSTNs). For RSTNs defined on a two-dimensional square lattice, we perform extensive numerical […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Mark J. Bowick, Nikta Fakhri, M. Cristina Marchetti, Sriram Ramaswamy, | Summary: This article summarizes some of the open questions in the field of active matter that have emerged during Active20, a nine-week program held at the Kavli Institute for Theoretical Physics (KITP) in Spring 2020. […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Pradyumna Reddy, Zhifei Zhang, Matthew Fisher, Hailin Jin, Zhaowen Wang | Summary: Fonts are ubiquitous across documents and come in a variety of styles. They are either represented in a native vector format or rasterized to produce fixed resolution images. In the first case, the non-standard representation […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Curtis McCully, Saurabh W. Jha, Richard A. Scalzo, D. Andrew Howell, Ryan J. Foley | Summary: Type Iax supernovae represent the largest class of peculiar white-dwarf supernovae. The type Iax SN~2012Z in NGC 1309 is the only white dwarf supernova with a detected progenitor system in pre-explosion […]
Kavli Affiliate: David Gross | First 5 Authors: Tim Fuchs, David Gross, Peter Jung, Felix Krahmer, Richard Kueng | Summary: Low-rank matrix recovery problems arise naturally as mathematical formulations of various inverse problems, such as matrix completion, blind deconvolution, and phase retrieval. Over the last two decades, a number of works have rigorously analyzed the […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Sagar Vijay, Matthew P. A. Fisher, , | Summary: Monitored quantum dynamics reveal quantum state trajectories which exhibit a rich phenomenology of entanglement structures, including a transition from a weakly-monitored volume law entangled phase to a strongly-monitored area law phase. For one-dimensional hybrid […]
