Order parameters and ground-state phase diagram of the interacting topological Su-Schrieffer-Heeger model with extended-range hoppings

This paper investigates the interacting Su-Schrieffer-Heeger model with extended-range hoppings, revealing a rich ground-state phase diagram comprising topological, superconducting-like, and charge-density-wave phases, and derives order parameters that demonstrate how interactions enable non-unidirectional hoppings distinct from the non-interacting case.

Strain-Induced Tuning of Third-Harmonic Generation in Monolayer Black Phosphorene

This study utilizes a tight-binding model and semiconductor Bloch equations to demonstrate that strain engineering, particularly along the out-of-plane direction, effectively tunes the third-harmonic generation in monolayer black phosphorene by synergistically modulating its bandgap and Berry connection, thereby enabling dynamic control of nonlinear optical responses for reconfigurable infrared photonic devices.

Layer-parity-defined surface polarization in Nb3_3Cl8_8 for excitonic modulation at van der Waals interfaces

This study demonstrates that the layer-parity-dependent surface polarization in Nb3_3Cl8_8, arising from its intrinsic breathing kagome lattice symmetry breaking, enables direct control over adjacent excitonic emission in van der Waals heterostructures through tunable interfacial band alignment and charge transfer.
