Kavli Affiliate: L. Mahadevan | First 5 Authors: F. Mori, L. Mahadevan, , , | Summary: Inspired by the intermittent reorientation strategy seen in the behavior of the dung beetle, we consider the problem of the navigation strategy of an active Brownian particle moving in two dimensions. We assume that the heading of the particle […]
Kavli Affiliate: James Bock | First 5 Authors: Samuel S. Condon, Stephen Padin, James Bock, Howard Hui, Phillip Korngut | Summary: We describe a technique for measuring focus errors in a cryogenic, wide-field, near-infrared space telescope. The measurements are made with a collimator looking through a large vacuum window, with a reflective cold filter to […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Isidora Araya Day, Kostas Vilkelis, Antonio L. R. Manesco, A. Mert Bozkurt, Valla Fatemi | Summary: We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet. The chirality and the number of quantized […]
Kavli Affiliate: Srijit Goswami | First 5 Authors: Christian G. Prosko, Wietze D. Huisman, Ivan Kulesh, Di Xiao, Candice Thomas | Summary: We study a phase-tunable four-terminal Josephson junction formed in an InSbAs two-dimensional electron gas proximitized by aluminum. By embedding the two pairs of junction terminals in asymmetric DC SQUIDs we can control the […]
Kavli Affiliate: L. Mahadevan | First 5 Authors: Sumit Sinha, Vishaal Krishnan, L Mahadevan, , | Summary: Active many-body systems composed of many interacting degrees of freedom often operate out of equilibrium, giving rise to non-trivial emergent behaviors which can be functional in both evolved and engineered contexts. This naturally suggests the question of control […]
Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Occlusions between consecutive frames have long posed a significant challenge in optical flow estimation. The inherent ambiguity introduced by occlusions directly violates the brightness constancy constraint and considerably hinders pixel-to-pixel matching. To address this issue, multi-frame optical flow methods leverage […]
