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.
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.
This paper reports the observation of efficient transport kinetics with anomalously high mobility in spatially indirect excitons within van der Waals heterostructures, a phenomenon that persists despite in-plane disorder and aligns with predictions of exciton superfluidity.
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.
This study reports that disorder in bulk WTe 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.
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.
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.
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.
This paper theoretically demonstrates that non-circular Corbino Josephson junctions on topological insulators exhibit reentrant superconductivity with a period halved in the topological case compared to the trivial one, offering a potential signature for detecting topological superconductivity.
This paper proposes and numerically demonstrates that Andreev spin qubits can be realized and manipulated via microwave-induced electric dipole transitions in magnetically doped, proximized topological insulator Josephson junctions, enabling the execution of quantum logic gates without external Zeeman fields or ancillary states.
