Entanglement phase transitions in random stabilizer tensor networks

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 […]

Unveiling a critical stripy state in the triangular-lattice SU(4) spin-orbital model

Kavli Affiliate: Yi Zhou | First 5 Authors: Hui-Ke Jin, Rong-Yang Sun, Hong-Hao Tu, Yi Zhou, | Summary: The simplest spin-orbital model can host a nematic spin-orbital liquid state on the triangular lattice. We provide clear evidence that the ground state of the SU(4) Kugel-Khomskii model on the triangular lattice can be well described by […]

A Multi-Implicit Neural Representation for Fonts

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 […]

Proof methods for robust low-rank matrix recovery

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 […]

Enhanced spin-orbit coupling and orbital moment in ferromagnets by electron correlations

Kavli Affiliate: Bo Gu | First 5 Authors: Ze Liu, Jing-Yang You, Bo Gu, Sadamichi Maekawa, Gang Su | Summary: In atomic physics, the Hund rule says that the largest spin and orbital state is realized due to the interplay of the spin-orbit coupling (SOC) and the Coulomb interactions. Here, we show that in ferromagnetic […]

Entanglement Domain Walls in Monitored Quantum Circuits and the Directed Polymer in a Random Environment

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 […]
