Topological Phases on Quantum Trees
Alex Westström, Wenbu Duan, Kangpei Yao +3
In this work, we present a theory for topological phases for quantum systems on tree graphs. Conventionally, topological phases of matter have been studied in regular lattices, but…

The humidity sensing properties and mechanism of strontium-hexaferrite ceramics
Hui-Feng Zhang, Jian Li, Gang-Qin Shao +3
The humidity sensitivity of n-type strontium-hexaferrite semiconductors, X-type (Sr2Co2Fe28O46) and Z-type (Sr3Co2Fe24O41), are investigated at room temperature. The contact and re…

One dimensional zone center phonons in space group
Jian Li, Jiufeng J. Tu, Joseph L. Birman
Motivated by experiments, we performed a systematic study on the one dimensional zone center phonons in space groups. All the one dimensional phonon modes for different Wyc…
