Exact Mobility Edges in a Disorder-Free Dimerized Stark Lattice with Effective Unbounded Hopping
Yunyao Qi, Heng Lin, Quanfeng Lu +2
We propose a disorder-free one-dimensional single-particle Hamiltonian hosting an exact mobility edge (ME), placing the system outside the assumptions of no-go theorems regarding u…
Dimer-driven multiple reentrant localization with composite potential
Pei-Jie Chang, Dong Ruan, Gui-Lu Long
Recent studies have revealed reentrant localization transitions in quasi-periodic one-dimensional lattices, where the competition between dimerized hopping and staggered disorder p…
The Evolution of Quantum Secure Direct Communication: On the Road to the Qinternet
Dong Pan, Gui-Lu Long, Liuguo Yin +5
Communication security has to evolve to a higher plane in the face of the threat from the massive computing power of the emerging quantum computers. Quantum secure direct communica…
Investigation of reentrant localization transition in one-dimensional quasi-periodic lattice with long-range hopping
Pei-Jie Chang, Qi-Bo Zeng, Jinghui Pi +2
Reentrant localization has recently been observed in systems with quasi-periodic nearest-neighbor hopping, where the interplay between dimerized hopping and staggered disorder is i…
