Electronic Transport Evidence for Topological Nodal-Line Semimetals of ZrGeSe single crystals
Lei Guo, Ting-Wei Chen, Chen Chen +8
Although the band topology of ZrGeSe has been studied via magnetic torque technique, the electronic transport behaviors related to the relativistic Fermions in ZrGeSe are still unk…
Topological Band Engineering of Graphene Nanoribbons
Daniel J. Rizzo, Gregory Veber, Ting Cao +6
Topological insulators (TIs) are an emerging class of materials that host highly robust in-gap surface/interface states while maintaining an insulating bulk. While most notable sci…
Surface Gap Solitons in Exciton Polariton Condensates
Ting-Wei Chen, Szu-Cheng Cheng
A gap soliton is a solitonic state existing inside the band gap of an infinite-periodic exciton-polariton condensate (EPC). The combination of surface states and gap solitons forms…
Ring dark solitons in microcavity polariton condensates
Szu-Cheng Cheng, Ting-Wei Chen
A ring dark soliton is a dark soltion occurring in higher dimensions. It is still unknown in microcavity-polariton condensates due to its instability. We find that a stable RDS can…
Phase diagram of microcavity polariton condensates with a harmonic potential trap
Ting-Wei Chen, Min g-Dar Wei, Szu-Cheng Cheng +1
We theoretically explore the phase transition in inhomogeneous exciton-polariton condensates with variable pumping conditions. Through Bogoliubov excitations to the radial-symmetri…
Stability and Excitations of Spontaneous Vortices in Homogeneous Polariton Condensates
Ting-Wei Chen, Szu-Cheng Cheng, Wen-Feng Hsieh
We study the dynamics of spontaneously formed vortices in homogeneous microcavity-polariton condensates (MPCs). We find that vortices are stable and appear spontaneously without st…
Collective Excitations, Nambu-Goldstone Modes and Instability of Inhomogeneous Polariton Condensates
Ting-Wei Chen, Szu-Cheng Cheng, Wen-Feng Hsieh
We study non-equilibrium microcavity-polariton condensates (MPCs) in a harmonic potential trap theoretically. We calculate and analyze the steady state, collective-excitation modes…
