Chaotic dynamics in a quantum Fermi-Pasta-Ulam problem
Alexander L. Burin, Andrii O. Maksymov, Ma'ayan Schmidt +1
We investigate the emergence of chaotic dynamics in a quantum Fermi - Pasta - Ulam problem for anharmonic vibrations in atomic chains applying semi-quantitative analysis of resonan…
Existence of electron and hole pockets and partial gap opening in the correlated semimetal Ca3Ru2O7
Hui Xing, Libin Wen, Chenyi Shen +9
The electronic band structure of correlated Ca3Ru2O7 featuring an antiferromagnetic as well as a structural transition has been determined theoretically at high temperatures, which…
Band dependence of charge density wave in quasi-one-dimensional Ta2NiSe7 probed by orbital magnetoresistance
Jiaming He, Yiran Zhang, Libin Wen +8
Ta2NiSe7 is a quasi-one-dimensional (quasi-1D) transition-metal chalcogenide with Ta and Ni chain structure. An incommensurate charge-density wave (CDW) in this quasi-1D structure…
Local Coefficients Revisited
Slawomir Kwasik, Fang Sun
Two simple "simplicial approximation" tricks are invoked to prove basic results involving (co)-homology with local coefficients.
