Type-II Ising Pairing in Few-Layer Stanene

Kavli Affiliate: Joseph Falson | First 5 Authors: Joseph Falson, Yong Xu, Menghan Liao, Yunyi Zang, Kejing Zhu | Summary: Spin-orbit coupling has proven indispensable in realizing topological materials and more recently Ising pairing in two-dimensional superconductors. This pairing mechanism relies on inversion symmetry breaking and sustains anomalously large in-plane polarizing magnetic fields whose upper […]

Andreev reflection at the interface with an oxide in the quantum Hall regime

Kavli Affiliate: Joseph Falson | First 5 Authors: Yusuke Kozuka, Atsushi Sakaguchi, Joseph Falson, Atsushi Tsukazaki, Masashi Kawasaki | Summary: Quantum Hall/superconductor junctions have been an attractive topic as the two macroscopically quantum states join at the interface. Despite longstanding efforts, however, experimental understanding of this system has not been settled yet. One of the […]

Harnessing Avidity: Quantifying Entropic and Energetic Effects of Linker Length and Rigidity Required for Multivalent Binding of Antibodies to HIV-1 Spikes

Kavli Affiliate: Pamela J. Bjorkman | First 5 Authors: Tal Einav, Shahrzad Yazdi, Aaron Coey, Pamela J. Bjorkman, Rob Phillips | Summary: Due to the low density of envelope (Env) spikes on the surface of HIV-1, neutralizing IgG antibodies rarely bind bivalently using both antigen-binding arms (Fabs) to crosslink between spikes (inter-spike crosslinking), instead resorting […]

A 1.6:1 Bandwidth Two-Layer Antireflection Structure for Silicon Matched to the 190-310 GHz Atmospheric Window

Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Fabien Defrance, Cecile Jung-Kubiak, Jack Sayers, Jake Connors, Clare deYoung | Summary: Although high-resistivity, low-loss silicon is an excellent material for THz transmission optics, its high refractive index necessitates antireflection treatment. We fabricated a wide-bandwidth, two-layer antireflection treatment by cutting subwavelength structures into the silicon surface […]

Yield precursor dislocation avalanches in small crystals: the irreversibility transition

Kavli Affiliate: Julia R. Greer | First 5 Authors: Xiaoyue Ni, Haolu Zhang, Danilo B. Liarte, Louis W. McFaul, Karin A. Dahmen | Summary: The transition from elastic to plastic deformation in crystalline metals shares history dependence and scale-invariant avalanche signature with other non-equilibrium systems under external loading: dilute colloidal suspensions, plastically-deformed amorphous solids, granular […]
