This paper employs rigorous yet intuitive symmetry arguments to revisit the calculation of the magnetic field at a point dipole's site, deriving new results relevant to fundamental problems in two-dimensional physics for upper-level undergraduate courses.
This paper establishes an exact angular symmetry selection rule explaining how trigonal warping activates and controls the sign of band-edge shift currents in two-dimensional inversion-broken systems like multilayer graphene and kagome lattices, a phenomenon governed by a signed three-point Bargmann invariant that remains invisible to conventional positive-definite metrics like the quantum metric.
This paper proposes and demonstrates that twisted monolayer-rhombohedral graphene serves as a promising platform for realizing hybrid electronic networks where localized nearly flat-band states and propagating quasi-one-dimensional modes coexist within the same energy window.
This paper uses nonequilibrium Green's function formalism to demonstrate that strong light-matter coupling in a doped quantum well creates observable inelastic sidebands in current-voltage characteristics, offering a realistic pathway to detect cavity-induced modifications of charge transport.
This paper presents a full spatial-dependence theoretical framework for nonlinear wave propagation in high-kinetic-inductance transmission lines, demonstrating how asymmetric impedance barriers enable strong, magnet-free diode effects and complex spectral distortions in superconducting microwave resonators.
This paper establishes a group-theoretical framework tailored to 2D photonic crystals to elucidate the symmetry origins of local k-space topology and Berry phase, demonstrating how structural design and symmetry perturbations can be leveraged to manipulate these topological features across diverse artificial wave systems.
This study reveals that electron-beam-induced charging drives unstable cathodoluminescence in colloidal quantum dots by promoting multiexciton generation, and demonstrates that this instability can be effectively controlled through indirect excitation and ligand engineering to enable stable spectroscopy and device processing.
This study employs pulsed nanocalorimetry to map the layer- and field-dependent magnetic thermodynamics of 2D CrSBr, revealing a dimensional crossover from bulk-like antiferromagnetism to intralayer ferromagnetism, a distinct odd-even layer parity effect, and the suppression of magnetic order by in-plane fields.
This paper predicts and theoretically characterizes a boundary Kerr effect in weakly doped zinc-blende semiconductors where a longitudinal electric field converts optically induced interband coherence into an edge-localized, helicity-odd polarization, providing a direct probe of multiband quantum kinetics without requiring spin-orbit coupling or intra-band accumulation.
Using phase-resolved terahertz time-domain spectroscopy, this study reveals that Landau polaritons in a GaAs-based two-dimensional electron gas exhibit a delayed onset of Rabi oscillations corresponding to one cavity round-trip time, demonstrating that the strong-coupling regime is established only after the cavity mode field fully forms.
