  "abstract": "We propose that unconventional Josephson effects can typically emerge in PT-symmetric antiferromagnetic (AFM) bilayer systems. When proximitized by a conventional superconductor, these heterostructures host dominant interlayer pairing correlation that features a distinctive spin texture enabled by the strong exchange field. Specifically, we demonstrate a novel mechanism for electrically tunable 0-π oscillations in lateral Josephson junctions, controlled by an out-of-plane electric displacement field. This behavior originates from field-induced finite-momentum pairing correlation, a hallmark of the unique layer-pseudospin structure in PT-symmetric AFM bilayers. Furthermore, we introduce a AFM Josephson spin valve based on these exotic proximity-induced spin-layer-locked pairing correlation, in which the supercurrent exhibits a strong dependence on the internal Néel order. Our findings establish PT-symmetric AFM bilayers as a versatile platform for phase-controllable Josephson junctions and superconducting magnetic random-access memory, with promising applications in superconducting circuits and ultralow-power computing.",
