This study experimentally maps the topological band structure of three-terminal graphene Josephson junctions using tunnelling spectroscopy and magnetic flux control, revealing a transition from gapped to gapless Andreev bound states that mimics nodal-line semimetals and demonstrates the potential for engineering higher-dimensional topological phases.
This study demonstrates that the Josephson current in the quantum Hall regime is mediated by counter-propagating edge states confined to physical edges, resolving previous ambiguities regarding its mechanism through a systematic comparison of various edge configurations in graphene devices.
This paper demonstrates that hybrid systems combining -wave unconventional magnets and -wave superconductors induce an -wave-like superconducting state characterized by zero-energy flat bands, odd-frequency pairing, and tunable Josephson currents driven by the interplay between noncollinear magnetic order and singlet pairing.
This paper proposes that a finite-momentum pair-density-wave (PDW) state in magic-angle twisted bilayer graphene reconciles observed tunneling signatures with low-temperature superfluid stiffness suppression by generating Bogoliubov Fermi surfaces, thereby establishing a direct experimental link between zero-bias conductance and phase rigidity.
This paper presents an exactly solvable model demonstrating that Fermi arcs in underdoped cuprates not only produce a superconducting dome consistent with experiments but also analytically suppress the transition temperature and enhance the gap-to- ratio through many-body effects beyond simple Fermi surface reduction.
Using high-flux synchrotron X-ray diffraction, researchers discovered a previously overlooked polar, checkerboard charge order in bilayer nickelate LaNiO that breaks glide-mirror symmetry and competes with its high-temperature superconducting phase, offering new insights into the mechanism of pressure-induced superconductivity.
This study utilizes time-dependent Ginzburg-Landau simulations of asymmetric Nb/V/Ta trilayer heterostructures to demonstrate that the superconducting diode effect arises from the interplay of Lorentz forces and asymmetric vortex dynamics, which can be significantly modulated or entirely suppressed by altering the layer stacking order.
This paper introduces soliton_solver, an open-source, GPU-accelerated Python package that utilizes a modular, theory-agnostic architecture to efficiently simulate and visualize topological solitons across diverse two-dimensional non-linear field theories.
This paper presents a numerical model of SNSPD absorption that incorporates quantum-corrected optical conductivity of niobium nitride films, demonstrating that the detector's wavelength range is significantly influenced by the material's optical properties rather than solely by its geometric cavity parameters.
This paper demonstrates that compact scalar field theories on lattices, through generic quantum geometric couplings acting as quantum gyrators, map to systems of non-identical anyons with fractional exchange phases, thereby enabling a new class of non-local field theories that break the Wigner superselection rule and facilitate all-to-all qubit gates via local control.
