Impurity-induced resonant states in topological nodal-line semimetals
Tao Zhou, Wei Chen, Yi Gao +1
Nodal-line semimetals are characterized by a kind of topologically nontrivial bulk-band crossing, giving rise to almost flat surface states. Yet, a direct evidence of the surface s…
General response theory of topologically stable Fermi points and its implications for disordered cases
Y. X. Zhao, Z. D. Wang
We develop a general response theory of gapless Fermi points with nontrivial topological charges for gauge and nonlinear sigma fields, which asserts that the topological character…
Probing Quantitatively Two-electron Entanglement with a Spintronic Quantum Eraser
W. Chen, R. Shen, Z. D. Wang +3
We design an ingenious spintronic quantum eraser to quantitatively probe the two-electron entanglement. It is shown that the concurrence of two spin-entangled electrons is directly…
Projective Ribbon Permutation Statistics: a Remnant of non-Abelian Braiding in Higher Dimensions
Michael Freedman, Matthew B. Hastings, Chetan Nayak +3
In a recent paper, Teo and Kane proposed a 3D model in which the defects support Majorana fermion zero modes. They argued that exchanging and twisting these defects would implement…
Topological properties of Abelian and non-Abelian quantum Hall states from the pattern of zeros
Xiao-Gang Wen, Zhenghan Wang
It has been shown that different Abelian and non-Abelian fraction quantum Hall states can be characterized by patterns of zeros described by sequences of integers {S_a}. In this pa…
Large Fourier transforms never exactly realized by braiding conformal blocks
Michael H. Freedman, Zhenghan Wang
Fourier transform is an essential ingredient in Shor's factoring algorithm. In the standard quantum circuit model with the gate set $\{\U(2), \textrm{CNOT}\}$, the discrete Fourier…
