TL;DR: The polarization of the ferroelectric BiFeO3 subjected to different electrical boundary conditions by heterointerfaces was imaged with atomic resolution using a spherical aberration-corrected transceiver as discussed by the authors.

TL;DR: In this article, the authors used aberrationcorrected transmission electron microscopy to follow the kinetics and dynamics of ferroelectric switching at millisecond temporal and subangstrom spatial resolution in an epitaxial bilayer of an antiferromagnetic (BiFeO3) on a ferromagnetic electrode (La 0.7Sr0.3MnO3).

TL;DR: In this paper, a flip-chip process is used to bond a chip with superconducting flux qubits to another chip containing structures for qubit readout and control, and the authors demonstrate that high qubit coherence is maintained in a flipchip geometry in the presence of galvanic, capacitive, and inductive coupling between the chips.

TL;DR: In this paper, the effect of ionizing radiation from environmental radioactive materials and cosmic rays contributes to the observed difference in the density of the broken Cooper pairs, referred to as quasiparticles, which is orders of magnitude higher than the value predicted at equilibrium by the Bardeen-Cooper-Schrieffer theory.

TL;DR: In this paper, the authors realized a giant atom by coupling small atoms to a waveguide at multiple, but well separated, discrete locations, enabling tunable atom-waveguide couplings with large on-off ratios and a coupling spectrum that can be engineered by device design.
