This study reports the in situ synthesis of TaAs2 nanowires encapsulated in SiO2, which exhibit giant magnetoresistance and coherent quantum surface transport signatures consistent with multiple intertwined topological phases, offering a promising platform for spintronics and nanoscale quantum technologies.
This paper demonstrates that coupling a topological insulator-based Josephson junction to a dissipative environment induces spectral bifurcation and finite lifetimes for Majorana bound states, ultimately driving an anomalous supercurrent at zero phase difference.
This paper establishes a velocity gauge theoretical framework for computing nonlinear optical responses in Floquet-driven quantum systems, demonstrating its equivalence to the length gauge while revealing unique phenomena like photon-assisted transitions and Floquet-induced photocurrents with applications in ultrafast spectroscopy and optoelectronics.
This study demonstrates that ultrathin SrIrO3/SrRuO3 heterostructures exhibit an emergent insulator-to-metal transition driven by interface-induced magnetic reconstruction, where a staggered Dzyaloshinskii-Moriya interaction stabilizes ferromagnetism to generate novel electronic properties unattainable in the individual antiferromagnetic insulating layers.
This study utilizes time-resolved pump-probe Faraday ellipticity measurements to demonstrate that increasing the number of vertically coupled InAs/InAlGaAs quantum dot layers in telecom C-band samples induces a transition from electron to hole residency, alters spin dephasing and relaxation dynamics, and enables the observation of hole spin mode locking with a coherence time of approximately 13 ns.
Using dynamical mean field theory, this study reveals that a strongly correlated Josephson junction exhibits a first-order transition between a Mott-like insulating phase and a proximitized superconducting phase, which can be tuned via phase bias and junction transparency to switch between conducting and insulating regimes.
This paper identifies a "fourth-order closure obstruction" in circular kinetic magnetotransport, demonstrating that truncating the angular momentum hierarchy at the stress level neglects a critical back-action from higher Fermi-surface harmonics that generates a fourth-order term in the current eigenvalue, which becomes chiral and can induce Hall sign reversal under magnetic fields.
This paper presents a generalized theoretical framework for Andreev reflection spectroscopy that incorporates spin-dependent anisotropic scattering to accurately interpret spin polarization and conductance in various magnetic materials, thereby resolving limitations of isotropic models and enabling robust spin-polarized current generation for advanced spintronic and quantum technologies.
This paper establishes a complete thermodynamic framework for radiative spin caloritronics by predicting the spin thermal Hall effect in nonreciprocal magneto-optical systems, where longitudinal radiative heat currents generate transverse spin angular momentum accumulation, and demonstrating that this phenomenon and its inverse form an Onsager-Casimir reciprocal pair subject to fundamental thermodynamic bounds.
The study demonstrates that introducing Janus-induced mirror-symmetry breaking in MoSSe/MoS2 bilayers promotes atomic reconstruction into distorted aperiodic patterns, which significantly weakens interlayer coupling and amplifies the twist-angle dependence of thermal conductance by nearly an order of magnitude compared to conventional twisted bilayer MoS2.
