Non-Abelian Ginzburg-Landau Theory of Spin Triplet Superconductivity

This paper presents an SU(2)×U(1) generalization of the Ginzburg-Landau theory for spin-triplet ferromagnetic superconductivity, describing a system with massive photons and non-Abelian magnons, massless neutral magnons, and a Higgs scalar field that exhibits unique features such as non-Abelian Meissner effects, dual conserved supercurrents, and distinct magnetic and spin vortices and monopoles.

Stability, electronic disruption, and anisotropic superconductivity of hydrogenated trilayer metal tetraborides (MB4_{4}H; M=Be, Mg, Ca, Al)

This study predicts that hydrogenated trilayer metal tetraborides (MB4_4H; M=Be, Mg, Ca, Al) are dynamically stable, exhibit multi-gap superconductivity driven by strong electron-phonon coupling, and possess tunable transition temperatures up to 64 K, with CaB4_4H showing the highest potential for high-TcT_c applications.

From Ferrimagnetic Insulator to superconducting Luther-Emery Liquid: A DMRG Study of the Two-Leg Lieb Lattice

Using density matrix renormalization group (DMRG) simulations motivated by recent ultracold atom experiments, this study reveals that the two-leg Lieb ladder Hubbard model transitions from a ferrimagnetic Mott insulator at half-filling to a Luttinger liquid at lower fillings, with a distinct superconducting Luther-Emery phase exhibiting dominant sxys_{xy}-wave pairing emerging in a narrow window near the critical filling of nc≈2/3n_c \approx 2/3.

Visualizing the interplay of dual electronic nematicities in kagome superconductors

By combining scanning tunneling microscopy with Ginzburg-Landau analysis, this study reveals that the kagome superconductor CsV3_3Sb5_5 hosts two distinct, coexisting electronic nematic orders—one tied to charge density waves and another to V-dx2−y2d_{x^{2}-y^{2}} orbital distortions—that exhibit complex interplay, temperature-dependent alignment, and persistence even when long-range CDW order is suppressed.

Band-basis decomposition of superfluid weight in magic-angle twisted bilayer graphene: Quantifying geometric and conventional contributions

This paper decomposes the superfluid weight in magic-angle twisted bilayer graphene into conventional and geometric contributions, revealing that while remote bands exclusively enhance the geometric component to approximately 55–58%, the geometric fraction peaks at 27–33% near the strongest superconducting fillings of ν=±2\nu = \pm 2.

Tractable model for a fractionalized Fermi liquid (FL∗^*) on a square lattice

This paper presents an analytically tractable microscopic model of a fractionalized Fermi liquid (FL∗^*) on a square lattice, where conduction electrons interact with a static Z2\mathbb{Z}_2 Yao-Lee spin liquid, revealing a small Fermi-surface phase that violates the Luttinger count and exhibits Fermi arcs and a divergent Sommerfeld coefficient, offering potential insights into the pseudogap phase of cuprates.

Angle evolution of the superconducting phase diagram in twisted bilayer WSe2

This study resolves the apparent discrepancy between superconducting phase diagrams in twisted bilayer WSe2_2 at different twist angles by demonstrating a smooth evolution of superconductivity across the range, revealing its consistent proximity to Fermi surface reconstruction and antiferromagnetic ordering rather than specific singularities, thereby establishing the system as a versatile platform for investigating correlated phases.

Inverse magnetic melting effect in vdW-like Kondo lattice CeSn0.75_{0.75}Sb2_2

This study reports the synthesis of single-crystalline quasi-two-dimensional Kondo lattice CeSn0.75_{0.75}Sb2_2 and demonstrates a rare inverse magnetic melting effect where low in-plane magnetic fields restore translational and rotational symmetries by transforming a fragile antiferromagnetic order and cluster glass ground state into a polarized paramagnetic phase.
