Kavli Affiliate: Cheng Peng | First 5 Authors: Taiming Lu, Tianmin Shu, Junfei Xiao, Luoxin Ye, Jiahao Wang | Summary: Understanding, navigating, and exploring the 3D physical real world has long been a central challenge in the development of artificial intelligence. In this work, we take a step toward this goal by introducing GenEx, a […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Stephen W. Yan, Diego Barberena, Matthew P. A. Fisher, Sagar Vijay, | Summary: We investigate a quantum dynamical phase transition induced by the competition between local unitary evolution and dissipation in a qubit chain with a strong, on-site $mathbb{Z}_2$ symmetry. While the steady-state of this […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Theodore J. Morin, Mingxiao Li, Federico Camponeschi, Hou Xiong, Deven Tseng | Summary: Heterogeneous integration of GaAs-based lasers with frequency doubling waveguides presents a clear path to scalable coherent sources in the so-called green gap, yet frequency doubling systems have so far relied on separately manufactured […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Kaizhen Sun, Jinghang Li, Kuan Dai, Bangyan Liao, Wei Xiong | Summary: Time-to-Collision (TTC) estimation lies in the core of the forward collision warning (FCW) functionality, which is key to all Automatic Emergency Braking (AEB) systems. Although the success of solutions using frame-based cameras (e.g., Mobileye’s solutions) […]
Kavli Affiliate: Leon Balents | First 5 Authors: Zhenhao Song, Tessa Cookmeyer, Leon Balents, , | Summary: We study the driven-dissipative Bose-Hubbard model with all-to-all hopping and subject to incoherent pumping and decay, as is naturally probed in several recent experiments on excitons in WS2/WSe2 moir’e systems, as well as quantum simulators. By positing a […]
Kavli Affiliate: Gang Su | First 5 Authors: Chuandi Zhang, Junsen Xiang, Cheng Su, Denis Sheptyakov, Xinyang Liu | Summary: Motivated by the recent observations of various exotic quantum states in the equilateral triangular-lattice phosphates Na$_2$BaCo(PO$_4$)$_2$ with $Jrm_{eff}$ = 1/2 and Na$_2$BaNi(PO$_4$)$_2$ with $S$ = 1, the magnetic properties of spin-5/2 antiferromagnet Na$_2$BaMn(PO$_4$)$_2$, their classical […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Bo Zhao, Jingyu Zhao, Zheng Zhu, Jian Wu, Zheng Liu | Summary: We propose to expand the territory of density functional theory to strongly-correlated electrons by reformulating the Kohn-Sham ansatz in the representation of fractionalized particles. We call it the ”KS* ansatz”. Using inhomogeneous t-J chains as […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Chaojun Ni, Guosheng Zhao, Xiaofeng Wang, Zheng Zhu, Wenkang Qin | Summary: Closed-loop simulation is crucial for end-to-end autonomous driving. Existing sensor simulation methods (e.g., NeRF and 3DGS) reconstruct driving scenes based on conditions that closely mirror training data distributions. However, these methods struggle with rendering novel […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Kaiwen Jiang, Venkataram Sivaram, Cheng Peng, Ravi Ramamoorthi, | Summary: Geometric reconstruction of opaque surfaces from images is a longstanding challenge in computer vision, with renewed interest from volumetric view synthesis algorithms using radiance fields. We leverage the geometry field proposed in recent work for stochastic opaque […]
