Topologically shadowed quantum criticality: A non-compact conformal manifold

This paper proposes that topological quantum critical points separating non-invertible chiral topological orders in (2+1) dimensions are described by a non-compact conformal manifold where the critical theory's topological angle is uniquely determined by the harmonic mean of the adjacent gapped phases' braiding angles, maintaining exact scale invariance without supersymmetry.

Nonlinear thermal gradient induced magnetization in dd^{\prime }, gg^{\prime } and ii^{\prime } altermagnets

This paper demonstrates that a finite magnetization can be induced by a second-order nonlinear temperature gradient in dd^{\prime }, gg^{\prime }, and ii^{\prime } altermagnets due to their specific spin-split band structures, whereas such a response is absent in their dd, gg, and ii counterparts as well as in various odd-parity magnets.

Room Temperature Anisotropic Photoresponse in Low-Symmetry van der Waals Semiconductor CrPS4_4

This paper demonstrates that the low-symmetry van der Waals semiconductor CrPS4_4 exhibits pronounced room-temperature optical and optoelectronic anisotropy, including strong linear dichroism and polarization-sensitive photocurrents driven by Cr3+^{3+} d-orbital transitions, establishing it as a promising platform for narrow-band polarized photodetectors and 2D spintronic devices.

Robust quantized thermal conductance of Majorana floating edge bands in d-wave superconductors

This paper proposes and characterizes a new class of floating Majorana edge bands (FMEBs) in time-reversal symmetry-breaking dd-wave superconductors, demonstrating through theoretical modeling and simulations that these isolated counterpropagating modes exhibit robust, quantized thermal conductance signatures that distinguish them from conventional chiral phases and offer a viable route for helical-like Majorana transport in topological quantum computation.

Indication of Stochastic Photothermal Dynamics around a Topological Defect in a Chiral Magnet

Using pump-probe Lorentz transmission electron microscopy, researchers discovered that the photothermal recovery of magnetic order in a chiral magnet exhibits stochastic dynamics and transient blurring around topological edge dislocations, suggesting that such defects enhance stochasticity during magnetic phase transitions.

Bias controlled Interlayer Exchange Coupling

This paper demonstrates through computer simulations and non-equilibrium Green's function calculations that an externally applied electrical bias can switch the sign of out-of-equilibrium interlayer exchange coupling in a ferromagnetic tri-layer system, particularly when strongly confined quantum well states are present, thereby enabling control over the magnetic configuration between parallel and anti-parallel states.
