This paper presents a design optimization scheme for magnetic tunnel junction-based sensors that balances flux concentrator gain and magnetic noise through finite element simulations and analytical modeling, ultimately achieving a three-orders-of-magnitude performance improvement over single-junction designs.
This paper identifies the internal low-energy symmetry of two-dimensional quadratic-band-touching Hamiltonians as the unitary symplectic group , constructs the corresponding rotationally invariant interacting theory, and demonstrates that for lattice systems like honeycomb, this symmetry reduces to the unitary group through the intersection of symplectic and orthogonal symmetries.
This review article examines the fundamental mechanisms, experimental advances, and theoretical insights regarding the formation and manipulation of chiral spin textures in van der Waals heterostructures, while outlining future challenges for developing robust, room-temperature spintronic devices.
This paper compares two Convolutional Recurrent Neural Network architectures for simulating crystal growth under variable supersaturation, demonstrating that explicitly conditioning the network on the supersaturation parameter yields superior high-fidelity predictions compared to implicit inference via input mini-sequences, while both models exhibit strong scalability to larger domains and longer time sequences.
This paper reports the successful on-surface synthesis and comprehensive characterization of a novel gulf-edged chiral graphene nanoribbon, establishing a new design motif that yields a 1.8 eV bandgap semiconductor while revealing distinctive vibrational fingerprints and ambient instability linked to edge features.
This study experimentally demonstrates that epitaxial bismuth films grown on ferromagnetic EuO(111) substrates form a stable, room-temperature quantum spin Hall insulator with edge-localized states, establishing a viable platform for realizing magnetically tunable higher-order topological phases.
This paper introduces a scaled gradient descent optimization algorithm to determine the ideal design parameters for SiC p-i-n diodes hosting divacancy spin centers, effectively minimizing optical linewidth and maximizing spin coherence while adhering to realistic physical constraints and mitigating leakage current noise.
This paper introduces a "cryogenic shock exfoliation" method combined with low-pressure van der Waals assembly to produce large-area, high-yield rhombohedral multilayer graphene devices exhibiting ultrahigh mobility and uniform correlated electron phases, thereby overcoming previous material abundance and fabrication limitations.
Using scanning tunneling potentiometry on two-dimensional bismuth films, researchers experimentally observed the crossover from diffusive to Landauer resistivity dipoles around defects of varying sizes, confirming Landauer's postulate of size-independent residual resistivity and enabling the estimation of key carrier parameters.
Using low-temperature scanning tunneling microscopy, researchers discovered that the van der Waals metal CeTe3 hosts versatile, competing antiferromagnetic charge-ordered states (stripe and checkerboard) tunable by modest magnetic fields, revealing a rich, strongly correlated electronic landscape that extends beyond weak-coupling descriptions and offers a new platform for engineering tunable nanoscale quantum states.
