3D Imaging of directional multi-scale cellulose nanostructures through multi-directional dark-field neutron tomography

This study demonstrates the use of multi-directional dark-field neutron tomography as a non-destructive, multi-scale imaging technique to visualize the 3D hierarchical nanoarchitecture and anisotropic orientation of cellulose nanofibrils in solid foams, overcoming the radiation damage and length-scale limitations of conventional X-ray and electron-based methods.

Valley separation of photoexcited carriers in bilayer graphene

This paper predicts an optical valley Hall effect in bilayer graphene, where trigonal warping in the gapless regime and circularly-polarized selection rules in the gapped regime enable the spatial separation of valley-polarized carriers to be optically detected, offering a pathway for terahertz optovalleytronic devices.

Emblems of pair density waves: dual identity of topological defects and their transport signatures

This paper proposes that mobile topological defects with a dual identity as both fractional vortices and crystalline dislocations serve as the primary mechanism for resistive switching and anisotropic transport in pure pair density wave states, offering a distinct experimental signature to confirm this intertwined order.

The Quadrupole Moment of Higher-Order Topological Insulator at Finite temperature

This paper investigates higher-order topological insulators at finite temperature using a generalized real-space quadrupole moment, revealing that while chiral symmetry ensures quantization, finite temperature can induce both standard and reentrant topological phase transitions, as well as disorder-driven topological Anderson transitions.

Disorder-driven Weyl-Kondo Semimetal Phase in WTe $_2$

This study reports that disorder in bulk WTe $_2$ drives anisotropic Kondo screening and pinning of the Fermi level near Weyl nodes, inducing a spontaneous Hall effect and establishing the material as a platform for disorder-tuned Weyl-Kondo fermions.

Weak-Memory Dynamics in Discrete Time

This paper establishes a mathematical theorem demonstrating that linear discrete-time dynamics with weak memory effects can be systematically reduced to a unique first-order Markovian evolution on an intermediate time scale, a result illustrated through applications to stochastic Floquet and quantum collisional models.

Machine-learned tuning to protected states by probing noise resilience

This paper presents a machine-learning method that utilizes noise injection and evolutionary strategies to automatically tune quantum systems, such as Kitaev chains, into protected regimes characterized by noise resilience and well-separated Majorana bound states.

Sachdev-Ye-Kitaev physics from the Hubbard model: A Floquet engineering approach

This paper demonstrates that applying a "kinetic driving" Floquet engineering technique to the Hubbard model, specifically the Bose-Hubbard model, effectively suppresses single-particle processes to generate quasi-random all-to-all interactions, thereby enabling a practical cold-atom quantum simulation of Sachdev-Ye-Kitaev (SYK) physics.
