ALT EDITORS' SUGGESTION Field theory of Borromean supercounterfluids 6 February, 2026 A Borromean counter-flow superfluid (BCSF) is a highly entangled state of 𝑁>2 atomic components. It occurs in the Mott insulating phase where the total flow is arrested. The authors solve here the problem of the dynamic field theoretical description of BCSF. The new model features Borromean hydrodynamics as a low-energy theory representing the symmetry of the 𝑈⁢(1)𝑁 factor group. It reveals a counter-flow AC Josephson effect, and generically predicts a first-order phase transition into a BCSF state in dimensions greater than two.

ALT EDITORS' SUGGESTION Coexisting massive and massless Dirac fermions in moiré-reconstructed bilayer graphene 6 February, 2026 Here, the authors show that a moiré superlattice in bilayer graphene aligned with hexagonal boron nitride drives a topological reconstruction of its electronic bands. Magnetotransport reveals the emergence of massless Dirac fermions in moiré minibands, coexisting with the parent bilayer’s massive carriers. The work highlights moiré engineering as a simple and versatile route to tunable band topology. Mohit Kumar Jat, Kenji Watanabe, Takashi Taniguchi, and Aveek Bid Phys. Rev. B 113, L081102 (2026)

ALT EDITORS' SUGGESTION Braiding Majoranas in a linear quantum dot–superconductor array: Mitigating the errors from Coulomb repulsion and residual tunneling 6 February, 2026 Demonstrating the exchange statistics of Majorana zero modes is a key step towards topological quantum computing. Recent progress in artificial Kitaev chains motivates this work, which develops a protocol for Majorana exchange. The authors define here a protocol to facilitate exchange, identify platform-specific challenges, study relevant noise sources, and analyze remedies and experimental constraints. With its results, the study provides practical guidance towards realizing braiding in artificial Kitaev chains. Sebastian Miles et al. Phys. Rev. B 113, 085302 (2026)

ALT EDITORS' SUGGESTION Ultrafast switching of antiferromagnetic order by field-derivative torque 5 February, 2026 Achieving fast and deterministic control of antiferromagnetic order remains a central challenge for next-generation spintronic devices. Here, the authors show that circularly polarized terahertz magnetic field pulses can deterministically switch antiferromagnetic order via field-derivative torque. By exploiting the time derivative of the applied field, their work significantly reduces switching thresholds and establishes a promising route toward ultrafast antiferromagnetic spintronics. The results reveal how tailoring pulse shape and damping can be used to optimize switching efficiency on sub-picosecond timescales. Pratyay Mukherjee and Ritwik Mondal Phys. Rev.

ALT EDITORS' SUGGESTION Anisotropic anomalous Hall effect in distorted kagome GdTi3⁢Bi4 3 February, 2026 Here, the authors experimentally observe the anisotropic anomalous Hall effect (AHE) in GdTi3Bi4, despite the isotropic magnetization along respective crystallographic directions. This observation contradicts the conventional scaling of AHE with magnetization. In the presence of spin-orbit coupling and broken time-reversal symmetry within the Gd 4𝑓 sublattice, the magnetization direction controls the orbital mixing in the Ti 𝑡2⁢𝑔 bands. This relocates the Berry curvature hot spots and produces orientation-selective AHE. These findings establish GdTi3Bi4 as a platform for novel quantum phenomena. Avdhesh K. Sharma et al. Phys. Rev.
