Emergent Spin Hall Quantization and High‐Order van Hove singularities in Square‐Octagonal MA2Z4

open access: yesAdvanced Physics Research, EarlyView.
Square‐octagonal MA2Z4 (M = Mo/W, A = Si/Ge, Z = pnictogen) monolayers are predicted to realize quantum spin Hall insulators with nearly quantized spin Hall conductivity enabled by an emergent spin U(1) quasi‐symmetry. Materials with Z = As and Sb host quasi‐flat bands with high‐order van Hove singularities near the Fermi level, making them promising ...

Spin Dynamics of Excitons and Carriers in Mixed‐Cation MAxFA1–xPbI3 Perovskite Crystals: Alloy Fluctuations Probed by Optical Orientation

open access: yesAdvanced Physics Research, EarlyView.
The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.

Vanity Fair as Allegory

open access: yes, 1979
William Makepeace Thakerey's novel Vanity Fair has been called many things: a social satire, a "realistic" novel whose realism is flawed by the author's "instructions," and much else. It has not, however, been seen as an allegory.

Resonant Tunneling in Laser‐Dressed Double‐Barrier Nanostructures: Role of Potential Geometry

open access: yesAdvanced Physics Research, EarlyView.
A schematic illustration of laser‐dressed double‐barrier nanostructures with rectangular, parabolic, and triangular potential profiles is presented. The intense laser field modifies the effective confinement potential, leading to a shift in resonance energies.
