Ultrafast optical control of charge orders in kagome metals

Posted by dbos Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yu-Ping Lin, Vidya Madhavan, Joel E. Moore, , | Summary: We show that ultrafast optical pump pulses provide effective control over charge orders in the kagome metals $A$V$_3$Sb$_5$ with $A=$ K, Rb, and Cs. Starting from the real charge density waves (rCDWs) at the $p$-type Van […]

M-VAR: Decoupled Scale-wise Autoregressive Modeling for High-Quality Image Generation

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Sucheng Ren, Yaodong Yu, Nataniel Ruiz, Feng Wang, Alan Yuille | Summary: There exists recent work in computer vision, named VAR, that proposes a new autoregressive paradigm for image generation. Diverging from the vanilla next-token prediction, VAR structurally reformulates the image generation into a coarse to fine […]
