Breakdown of Ergodicity and Self-Averaging in Polar Flocks with Quenched Disorder
Yu Duan, Benoît Mahault, Yu-qiang Ma +2
We show that spatial quenched disorder affects polar active matter in ways more complex and far-reaching than believed heretofore. Using simulations of the 2D Vicsek model subjecte…
Quantum verification of NP problems with single photons and linear optics
Aonan Zhang, Hao Zhan, Junjie Liao +5
Quantum computing is seeking to realize hardware-optimized algorithms for application-related computational tasks. NP (nondeterministic-polynomial-time) is a complexity class conta…
Physical properties revealed by transport measurements on superconducting NdSrNiO thin films
Ying Xiang, Qing Li, Yueying Li +3
The newly found superconductivity in infinite-layer nickelate superconducting films has attracted much attention, because their crystalline and electronic structures are similar to…
Tensor monopoles and negative magnetoresistance effect in optical lattices
Hai-Tao Ding, Yan-Qing Zhu, Zhi Li +1
We propose that a kind of four-dimensional (4D) Hamiltonians, which host tensor monopoles related to quantum metric tensor in even dimensions, can be simulated by ultracold atoms i…
-projective translational symmetry protected topological phases
Y. X. Zhao, Yue-Xin Huang, Shengyuan A. Yang
Symmetry is fundamental to topological phases. In the presence of a gauge field, spatial symmetries will be projectively represented, which may alter their algebraic structure and…
Two superconducting components with different symmetries in Nd1-xSrxNiO2 films
Qiangqiang Gu, Yueying Li, Siyuan Wan +8
The pairing mechanism in cuprates remains as one of the most challenging issues in the field of condensed matter physics. The unique 3d9 electron orbital of the Cu2+ ionic states i…
