Current-enabled optical conductivity of superconductors

Kavli Affiliate: Joel E. Moore | First 5 Authors: MichaƂ Papaj, Joel E. Moore, , , | Summary: In most superconductors, optical excitations require impurity scattering or the presence of multiple bands. This is because in clean single-band superconductors, the combination of particle-hole and inversion symmetries prevents momentum-conserving transitions. In this work we show how […]

How to grow a flat leaf

Kavli Affiliate: L. Mahadevan | First 5 Authors: Salem al-Mosleh, L. Mahadevan, , , | Summary: Growing a flat lamina such as a leaf is almost impossible without some feedback to stabilize long wavelength modes that are easy to trigger since they are energetically cheap. Here we combine the physics of thin elastic plates with […]

Unifying Motion Deblurring and Frame Interpolation with Events

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Lei Yu, , , | Summary: Slow shutter speed and long exposure time of frame-based cameras often cause visual blur and loss of inter-frame information, degenerating the overall quality of captured videos. To this end, we present a unified framework of event-based motion deblurring and […]

CP2: Copy-Paste Contrastive Pretraining for Semantic Segmentation

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Huiyu Wang, Chen Wei, Alan Yuille, Wei Shen | Summary: Recent advances in self-supervised contrastive learning yield good image-level representation, which favors classification tasks but usually neglects pixel-level detailed information, leading to unsatisfactory transfer performance to dense prediction tasks such as semantic segmentation. In this […]
