  Colossal magnetic tunability of excitons in 2D van der Waals magnetic semiconductor CrSBr

  Here, we report the observation of remarkably strong magneto-optical effects in the 2D magnetic semiconductor CrSBr that allow probing its magnetic order with unprecedented sensitivity.

  Jamming-controlled stochasticity in metal-insulator switching

  Sub-threshold currents erase the short-term memory defined by the nano-domain distribution, recovering stochastic switching, thus offering a path for in-device learning.

  Probing picosecond depairing currents in type-II superconductors

  Here we show that picosecond electrical pulses, which act on timescales too short for vortices to move, drive supercurrents up to the intrinsic depairing limit.

  Two-dimensional topological quantum chemistry and catalog of topological materials

  We found 4073 topological or obstructed entries, including 905 topological insulators and 1003 obstructed atomic insulators, greatly expanding the library of such materials in two dimensions.

  Approaching Landauer’s limit in a single superconducting vortex memory bit

  Although our experimental method requires a steady sinusoidal drive incompatible with Landauer’s erasure protocol, our numerical analysis demonstrates that the work required for such bit manipulation (erasure) is within an order of magnitude of Landauer’s limit ($k_{B}Tln2$) at 4.2 K. These findings open possibilities for creating highly efficient memory elements that could be integrated with cryogenic quantum circuits or function as topological quantum computing qubits; thereby contributing to memory devices with lower energy consumption and mitigating the escalating global energy demand in the computing industry.
