This paper demonstrates that static electron-phonon coupling in two-dimensional Rashba -wave altermagnets can induce anisotropic suppression and complete depolarization of the spin Edelstein effect via Fermi surface collapse, offering a reversible mechanism for controlling spin polarization in next-generation spintronic devices.
This paper proposes a microscopic framework and device-level pathway for spin-based true random number generation by demonstrating how voltage-controlled magnetic anisotropy can exponentially amplify intrinsic spin quantum fluctuations, enabling their dominance over thermal noise in magnetization dynamics for binary readout.
This paper proposes a Ramsey interferometry protocol using addressable impurities to coherently control and braid anyons in fractional Chern insulators, enabling the unambiguous separation and measurement of Aharonov-Bohm and exchange geometric phases for direct experimental verification of anyonic statistics.
This paper theoretically investigates the magnetotransport properties of a two-dimensional electronic system with unconventional Rashba spin-orbit coupling, revealing unique features such as intra-spin Landau level crossings, a distinct beating pattern in Shubnikov-de Haas oscillations arising from intra-spin band superposition, and double jumps in quantum Hall conductivity at crossing points.
This study presents a systematic theoretical investigation of orbital torque in Ti/FM and Cu/FM bilayers, revealing that the torque's dependence on the ferromagnetic species varies with the nonmagnetic metal source and originates from the bulk nonmagnetic layer, thereby offering microscopic insights for designing light-metal-based orbitronic devices.
This study constructs a low-energy effective Hamiltonian for [001]-oriented HgTe nanowires, revealing that while anisotropic terms induce an anticrossing at zero momentum, a band inversion transition still occurs at finite wave vectors for a critical radius of approximately 3.45 nm, and bulk inversion asymmetry does not cause spin splitting in the relevant subbands.
This paper proposes a two-step optomagnomechanical protocol that generates mechanical cat-like states by first creating a squeezed mechanical state via microwave-driven magnetostriction and then subtracting phonons through conditional detection of anti-Stokes photons from a weak red-detuned optical pulse.
This paper demonstrates that finite rectangular altermagnetic samples with unequal dimensions acquire a net spin polarization purely due to geometry, a phenomenon arising from the interplay between anisotropic spin-resolved Fermi contours and discrete momentum sampling that can be detected via characteristic transport signatures.
This paper proposes an unsupervised, physics-informed neural network model that learns to autotune quantum dot simulators toward Majorana zero modes by analyzing conductance maps, demonstrating that a single update or iterative procedure can successfully drive the system into a topological phase from a broad range of initial conditions.
This paper theoretically demonstrates that a bichromatic driving scheme can cancel second-order frequency shifts and reduce sensitivity to charge noise in germanium hole spin qubits, thereby enhancing single-qubit gate fidelity without requiring additional hardware or sacrificing control speed.
