Abstract: Significance The threshold for free vortex formation in a two-dimensional superconductor limits the temperatures below which the supercurrent flows without dissipation. Here, it is shown that an essential singularity in an electron’s wave function results… read more here.

Abstract: The quest for non-Abelian quasiparticles has inspired decades of experimental and theoretical efforts, where the scarcity of direct probes poses a key challenge. Among their clearest signatures is a thermal Hall conductance with quantized half-integer… read more here.
