Probing the pathway of an ultrafast structural phase transition to illuminate the transition mechanism in Cu2S
Junjie Li, Kai Sun, Jun Li +17
Disentangling the primary order parameter from secondary order parameters in phase transitions is critical to the interpretation of the transition mechanisms in strongly correlated…
Topological Effect of Surface Plasmon Excitation in Gapped Isotropic Topological Insulator Nanowires
Mingda Li, Wenping Cui, Lijun Wu +5
We present a theoretical investigation of the surface plasmon (SP) at the interface between topologically non-trivial cylindrical core and topological-trivial surrounding material,…
Spectroscopic Signatures of Nonlocal Interfacial Coupling in Superconducting FeSe/SrTiO3 Heterostructures
Nina Andrejevic, Fei Han, Thanh Nguyen +10
The mechanism of enhanced superconductivity in the one unit-cell (1UC) FeSe film on a SrTiO3 (STO) substrate has stimulated significant research interest but remains elusive. Using…
Theory of Electron-Phonon-Dislon Interacting System - Toward a Quantized Theory of Dislocations
Mingda Li, Yoichiro Tsurimaki, Qingping Meng +4
We provide a comprehensive theoretical framework to study how crystal dislocations influence the functional properties of materials, based on the idea of quantized dislocation, nam…
Ultrafast formation of topological defects in a 2D charge density wave
Yun Cheng, Alfred Zong, Lijun Wu +13
Topological defects play a key role in nonequilibrium phase transitions, ranging from birth of the early universe to quantum critical behavior of ultracold atoms. In solids, transi…
The Non-Perturbative Quantum Nature of the Dislocation-Phonon Interaction
Mingda Li, Zhiwei Ding, Qingping Meng +5
Despite the long history of dislocation-phonon interaction studies, there are many problems that have not been fully resolved during this development. These include an incompatibil…
Near-Field Optical Effect of a Core-Shell Nanostructure In Proximity to a Flat Surface
Wenping Cui, Mingda Li, Zuyang Dai +2
We provide an analytical solution to study the near field optical effect of a core-shell nanostructure in proximity to a flat surface, within quasi-static approximation. The distri…
