antichiral edge statemodified Haldane modeltopological circuitWe constructed an electrical circuit to realize a modified Haldane lattice exhibiting the unusual phenomenon of antichiral edge states. The circuit consists of a network of inductors and capacitors with interconnections reproducing the effects of ...
Based on the modified Haldane model, Colomés and Franz17 proposed the antichiral edge state propagating in the same direction along two parallel boundaries. As required by the conservation of flow momentum, the number of states must remain equal for the entire system toward left and right. As...
And the Fermi arc surface state dispersions of A-type (blue dashed line) and B-type (red dashed line) surfaces are degenerate and obliquely connect the two projected frequency-shifted WPs (W1+ and W2−), similar to that of the antichiral edge states connecting two projected frequency-...
Here we tackle this problem in a synthetic non-Hermitian Hall ladder and experimentally observe antichiral edge currents (ACECs) of photons, by tuning the locally uniform effective magnetic flux and the on-site gain/loss. Such ACECs provide a topological method to probe the signatures of the ...

A series of defocused Lorentz TEM images of this state is shown in Extended Data Fig. 5. c shows one skyrmionium, one skyrmion–antiskyrmion pair, two antiskyrmions at the lower edge and four skyrmions at the right edge. d shows two skyrmions and two antiskyrmions separated by a large ...
In this work, the density functional theory, the wavefunction analysis of the excited state, and the quantum theory of atoms in molecules are used to calculate and analyze the anti-symmetric chiral characteristics of zigzag-edge twisted bilayer graphene quantum dots based on periodic complementary ...
