RenderDiffusion: Image Diffusion for 3D Reconstruction, Inpainting and Generation

Posted by dbos November 17, 2022UCSB

Kavli Affiliate: Matthew Fisher | First 5 Authors: Titas Anciukevičius, Zexiang Xu, Matthew Fisher, Paul Henderson, Hakan Bilen | Summary: Diffusion models currently achieve state-of-the-art performance for both conditional and unconditional image generation. However, so far, image diffusion models do not support tasks required for 3D understanding, such as view-consistent 3D generation or single-view object […]

$d$-wave Superconductivity, Pseudogap, and the Phase Diagram of $t$-$t’$-$J$ Model at Finite Temperature

Posted by dbos November 11, 2022UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Dai-Wei Qu, Bin-Bin Chen, Xin Lu, Qiaoyi Li, Shou-Shu Gong | Summary: Recently, a robust $d$-wave superconductivity has been unveiled in the ground state of the 2D $t$-$t’$-$J$ model — with both nearest-neighbor ($t$) and next-nearest-neighbor ($t’$) hoppings — through the density matrix renormalization group calculations in […]

Entanglement Dynamics of the Non-Unitary Holographic Channel

Posted by klaurent November 8, 2022UCAS

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Masahiro Nozaki, Kotaro Tamaoka, Mao Tian Tan, | Summary: We study the dynamical properties of a strongly scrambling quantum circuit involving a projective measurement on a finite-sized region by studying the operator entanglement entropy and mutual information (OEE and BOMI) of the dual operator state […]

Spin hydrodynamic generation in unsteady flows

Posted by klaurent October 30, 2022November 7, 2022UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takumi Funato, Mamoru Matsuo, , , | Summary: We theoretically investigate a spin-mediated conversion from fluid dynamics to voltage, known as spin hydrodynamic generation (SHDG), in oscillatory and transient unsteady flows. We consider unsteady flows of liquid metal between two parallel infinite planes and then calculate its […]

On the Curious Case of $ell_2$ norm of Sense Embeddings

Posted by klaurent October 26, 2022November 7, 2022UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Danushka Bollegala, , , | Summary: We show that the $ell_2$ norm of a static sense embedding encodes information related to the frequency of that sense in the training corpus used to learn the sense embeddings. This finding can be seen as an extension of […]

Coherence requirements for quantum communication from hybrid circuit dynamics

Posted by klaurent October 20, 2022November 1, 2022UCSB

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Shane P. Kelly, Ulrich Poschinger, Ferdinand Schmidt-Kaler, Matthew P. A. Fisher, Jamir Marino | Summary: The coherent superposition of quantum states is an important resource for quantum information processing which distinguishes quantum dynamics and information from their classical counterparts. In this article we investigate the […]
