Magnetic penetration depth in topological superconductors: Effect of Majorana surface states and application for UTe2_2

This study demonstrates that magnetic penetration depth measurements in UTe2_2 can directly probe Majorana surface states and distinguish between different topological pairing symmetries, as surface contributions dominate the low-temperature TnT^n scaling behavior in low-κ\kappa superconductors while bulk quasiparticles govern the response in high-κ\kappa regimes.

Microscopic origin of the nemato-elastic coupling and dynamics of hybridized collective nematic-phonon excitations

This paper develops a microscopic formalism to demonstrate how impurity-enabled electron-phonon coupling generates hybridized, massless nemato-elastic collective modes near a nematic quantum critical point, revealing a complex landscape of underdamped and overdamped dynamics with significant implications for nematic-fluctuation-mediated superconductivity.

Chaos-generating periodic orbits of topological defects in confined active nematics

This study reveals that confined active nematics can transition from chaotic flows to ordered, periodic dynamics through stable orbits of +1/2+1/2 disclinations, where the specific "braid" patterns (such as "golden" and "silver" braids) emerge from a balance between the number of defects and flow vortices under strong confinement.

Paramagnon-Interference Mechanism for Three-Dimensional Bond Order in Kagome Metals AV3_3Sb5_5 (A=Cs, Rb, K): Analysis by the Density-Wave Equation

This paper establishes that the paramagnon-interference mechanism drives the emergence of a commensurate 3D $2\times 2\times 2bondorderinkagomemetalsAV bond order in kagome metals AV_3SbSb_5$, with the specific stacking pattern determined by the third-order Ginzburg-Landau term and the quasi-2D nature of the Fermi surface.

Discovery of Dynamical Heterogeneity in a Supercooled Magnetic Monopole Fluid

By measuring microsecond-resolved spontaneous magnetization fluctuations in Dy2Ti2O7, researchers directly detected dynamical heterogeneity in a supercooled magnetic monopole fluid, observing a sharp bifurcation in monopole noise and the emergence of correlated current bursts that evolve with escalating spatiotemporal scales as the system approaches the glass transition.

Parity readout in Majorana box qubits from the dispersive to the resonant regime

This paper presents a general theoretical framework for Majorana box qubit parity readout across the dispersive-to-resonant crossover, demonstrating that while semiclassical factorization is quantitatively accurate in the dispersive regime, it introduces small but measurable deviations in the resonant regime when compared to exact numerical solutions of the Lindblad master equation.

Competition between Charge Density Wave and Superconductivity in a Janus MXene Mo2NF2

This study reveals that in the Janus MXene Mo2NF2, a charge density wave instability driven by momentum-dependent electron-phonon coupling competes with superconductivity, but the latter can be enhanced and the former suppressed through compressive biaxial strain, thereby establishing Mo2NF2 as a tunable platform for controlling the interplay between these two quantum phases.

Continuum field theory of matchgate tensor network ensembles

This paper establishes a continuum field theory description for random ensembles of two-dimensional fermionic matchgate tensor networks, demonstrating that their disorder-averaged physics corresponds to a nonlinear sigma-model of symmetry class D with a topological term, thereby linking these discrete networks to the thermal quantum Hall problem and revealing a phase structure that includes localized phases, quantum Hall criticality, and a thermal metal.

Superconductivity as a Probe of Altermagnetism: Critical Temperature, Field, and Current

This paper utilizes Ginzburg-Landau theory to demonstrate that the coexistence of dd-wave altermagnetism and superconductivity in thin films produces characteristic fourfold anisotropies in critical temperature, parallel critical field, and critical current density, providing experimentally accessible signatures for detecting altermagnetism.

Magnetoelastic signatures of thermal and quantum phase transitions in a deformable Ising chain under a longitudinal and transverse magnetic field

This paper investigates a deformable spin-1/2 Ising chain under magnetic fields, revealing that longitudinal fields induce discontinuous thermal phase transitions with hysteresis, whereas transverse fields drive a continuous quantum phase transition, with both scenarios exhibiting distinct anomalies in magnetic and elastic properties.
