Commensurate-incommensurate Mott transition without magnetic field: emergence of nematic Luttinger liquid in XXZ chain

Posted by klaurent Delft

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Julien Fitouchi, Julien Fitouchi, , , | Summary: We investigate the zero-magnetization phase diagram of a spin-1/2 chain with competing ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchange couplings in the strongly interacting regime. Using density matrix renormalization group (DMRG) simulations, we discover two successive commensurate-incommensurate transitions of the […]

Flow4Agent: Long-form Video Understanding via Motion Prior from Optical Flow

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Ruyang Liu, Ruyang Liu, , , | Summary: Long-form video understanding has always been a challenging problem due to the significant redundancy in both temporal and spatial contents. This challenge is further exacerbated by the limited context length of Multimodal Large Language Models (MLLMs). To address this […]
