Superconductivity in Few-Layer Stanene
Menghan Liao, Yunyi Zang, Zhaoyong Guan +11
A single atomic slice of α-tin-stanene-has been predicted to host quantum spin Hall effect at room temperature, offering an ideal platform to study low-dimensional and topological…
Size Dependence and Ballistic Limits of Thermal Transport in Anisotropic Layered Two-Dimensional Materials
Zuanyi Li, Yizhou Liu, Lucas Lindsay +3
Layered materials have uncommonly anisotropic thermal properties due to their strong in-plane covalent bonds and weak out-of-plane van der Waals interactions. Here we examine heat…
Realizing an Epitaxial Stanene with an Insulating Bandgap
Yunyi Zang, Tian Jiang, Yan Gong +12
Stanene, a single atomic layer of Sn in a honeycomb lattice, is predicted a candidate wide bandgap two-dimensional (2D) topological insulator and can host intriguing topological st…
Pseudospins and topological effects of phonons in a Kekule lattice
Yizhou Liu, Chao-Sheng Lian, Yang Li +2
The search for exotic topological effects of phonons has attracted enormous interest for both fundamental science and practical applications. By studying phonons in a Kekulé lattic…
Berry Phase and Topological Effects of Phonons
Yizhou Liu, Yong Xu, Wenhui Duan
Phonons as collective excitations of lattice vibrations are the main heat carriers in solids. Tremendous effort has been devoted to investigate phonons and related properties, givi…
Unconventional quantum Hall effects in two-dimensional massive spin-1 fermion systems
Yong Xu, L. -M. Duan
Unconventional fermions with high degeneracies in three dimensions beyond Weyl and Dirac fermions have sparked tremendous interest in condensed matter physics. Here, we study quant…
