Quantum spin Hall crystals at fractional filling of twisted MoTe2_2

This paper predicts and classifies interaction-driven quantum spin Hall crystals (QSHCs) emerging at fractional fillings in twisted MoTe2_2, providing specific evidence for a 9-fold quasi-degenerate 3×3\sqrt{3}\times\sqrt{3} charge-ordered state at ν=−8/3\nu = -8/3 near a 5∘5^\circ twist that exhibits distinct topological phases protected by time-reversal or valley symmetry.

Origin of High-Temperature Antiferromagnetic Order in a van der Waals Material

The study reveals that substituting Co into Fe4GeTe2 induces layer-selective ordering and enhanced electronic correlations of quasi-localized Co 3d-states, which drive an unusually high-temperature antiferromagnetic order at 250 K in the van der Waals material (Fe0.65Co0.35)4GeTe2, establishing it as a promising candidate for AFM spintronics.

Signatures of a ferro-Josephson effect in twisted graphene

This paper reports experimental signatures of a ferro-Josephson effect in twisted graphene, where current-driven precession of spin-domain-wall moments generates topological electromotive forces manifesting as sharp, field-dispersive resonances in longitudinal resistance at ultra-low energy scales.

Metastable magnetic domains and the anomalous B∥=0B_\parallel=0 resistance peak in twisted double bilayer graphene

This paper identifies metastable domains of orbital magnetism, driven by spin-valley coupling and sensitive to gate-voltage trajectories and in-plane magnetic fields, as the microscopic origin of the anomalous zero-field resistance peak observed in the valley-polarized quarter-metal state of twisted double bilayer graphene.

Immittance formulas for exact blackbox quantization and divergence-free effective models in circuit QED

This paper presents simple, exact formulas for constructing Hamiltonians and divergence-free effective models for Josephson-junction-based superconducting qudits coupled to arbitrary passive linear environments, thereby extending blackbox quantization to multiport, dissipative, and nonreciprocal settings while eliminating spurious Lamb-shift divergences.

Electrical manipulation of oxygen stoichiometry in multiterminal YBa2_2Cu3_3O7−δ_{7-\delta} junctions

This study demonstrates that electrical currents can be used to selectively and directionally manipulate oxygen stoichiometry in specific branches of a multiterminal YBa2_2Cu3_3O7−δ_{7-\delta} device, enabling post-fabrication local tuning of superconducting properties through controlled oxygen vacancy migration.
