Subsymmetry-protected compact edge states
Ruoqi Cheng, Domenico Bongiovanni, Ziteng Wang +6
Sub-symmetry (SubSy) protected topological states represent a concept that goes beyond the conventional framework of symmetry-protected topological (SPT) phases, demonstrating that…
Quadratic Band Touching and Nontrivial Winding Reveal Generalized Angular Momentum Conservation
Yihan Wang, Domenico Bongiovanni, Dario Jukić +7
Angular momentum conservation stands as one of the most fundamental and robust laws of physics. In discrete lattices, however, its realization can deviate markedly from the continu…
Preserving quantum coherence in thermal noisy systems via qubit frequency modulation
Mahshid Khazaei Shadfar, Farzam Nosrati, Ali Mortezapour +3
Quantum coherence is a key resource underpinning quantum technologies, yet it is highly susceptible to environmental decoherence, especially in thermal settings. While frequency mo…
Multi-topological phases of matter
Ziteng Wang, Domenico Bongiovanni, Xiangdong Wang +7
The discovery of topological phases of matter and topological boundary states had tremendous impact on condensed matter physics and photonics, where topological phases are defined…
