Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Xiaoyang Huang, Lucile Savary, Leon Balents, | Summary: We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-diagonalize the dynamics. Expanding to the second order in gradients, which is beyond […]
Kavli Affiliate: Leon Balents | First 5 Authors: Jia-Xin Zhang, Wen O. Wang, Leon Balents, Lucile Savary, | Summary: The absence of a well-defined Fermi surface in flat-band systems challenges the conventional understanding of instabilities toward Landau order based on nesting. We investigate the existence of an intrinsic nesting structure encoded in the band geometry […]
Kavli Affiliate: Leon Balents | First 5 Authors: Matthew Ennis, Rabindranath Bag, Tessa Cookmeyer, Matthew B. Stone, Alexander I. Kolesnikov | Summary: TmZn2GaO5 is a newly synthesized triangular lattice magnet that exhibits a unique quantum phase characterized by strong Ising anisotropy, a pseudo-doublet crystal electric field ground state, and a low-energy gapped excitation at the […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Zeqi Gu, Difan Liu, Timothy Langlois, Matthew Fisher, Abe Davis | Summary: Recent diffusion-based methods have achieved impressive results on animating images of human subjects. However, most of that success has built on human-specific body pose representations and extensive training with labeled real videos. In this work, […]
Kavli Affiliate: David Gross | First 5 Authors: Birte Ostermann, Taylor Garnowski, Fabian Henze, Vaibhavnath Jha, Asra Dia | Summary: Quadratic unconstrained binary optimization problems (QUBOs) are intensively discussed in the realm of quantum computing and polynomial optimization. We provide a vast experimental study of semidefinite programming (SDP) relaxations of QUBOs using sums of squares […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Vikas Thamizharasan, Nikitas Chatzis, Iliyan Georgiev, Matthew Fisher, Difan Liu | Summary: We present mean-shift distillation, a novel diffusion distillation technique that provides a provably good proxy for the gradient of the diffusion output distribution. This is derived directly from mean-shift mode seeking on the distribution, and […]
Kavli Affiliate: David Gross | First 5 Authors: Fabian Henze, Viet Tran, Birte Ostermann, Richard Kueng, Timo de Wolff | Summary: Quantum computers can solve semidefinite programs (SDPs) using resources that scale better than state-of-the-art classical methods as a function of the problem dimension. At the same time, the known quantum algorithms scale very unfavorably […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Fridtjof Brauns, Myles O’Leary, Arthur Hernandez, Mark J. Bowick, M. Cristina Marchetti | Summary: The self-propulsion of +1/2 topological defects is a hallmark of active nematic fluids, where the defects are advected by the flow field they themselves generate. In this paper we propose a minimal […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Sadra Rahimi Kari, Paolo Pintus, John E. Bowers, Matt Robbins, Nathan Youngblood | Summary: We present a compact, resonant-based coherent modulator on a thin-film lithium niobate (TFLN) platform, addressing the growing demand for high-speed, energy-efficient modulators in modern telecommunications. The design incorporates Mach-Zehnder Interferometers (MZIs) with […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Nissim Maruani, Wang Yifan, Matthew Fisher, Pierre Alliez, Mathieu Desbrun | Summary: This paper proposes ShapeShifter, a new 3D generative model that learns to synthesize shape variations based on a single reference model. While generative methods for 3D objects have recently attracted much attention, current techniques often […]
