Recently, topolectrical circuits (TECs) boom in studying the topological states of matter. The
resemblance between circuit Laplacians and tight-binding models in condensed matter …

We employ electric circuit networks to study topological states of matter in non-Hermitian
systems enriched by parity-time symmetry PT and chiral symmetry anti-PT (APT). The …

We highlight a general theory to engineer arbitrary Hermitian tight-binding lattice models in
electrical LC circuits, where the lattice sites are replaced by the electrical nodes, connected …

The mathematical foundation of quantum mechanics is built on linear algebra, while the
application of nonlinear operators can lead to outstanding discoveries under some …

We study non-Hermitian higher-order Weyl semimetals (NHHOWSMs) possessing real
spectra and having inversion I (I-NHHOWSM) or time-reversal symmetry T (T-NHHOWSM) …

Non-hermiticity presents a vast newly opened territory that harbors new physics and
applications such as lasing and sensing. However, only non-Hermitian systems with real …

The eigennmodes in a non-Hermitian system containing nonreciprocal couplings may
exhibit an extreme localization, also known as non-Hermitian skin effect (NHSE), under …

We investigate the twisted topology of the complex eigenspectrum of a one-dimensional non-
Hermitian system under the influence of long-range unidirectional coupling. Unlike the …

We present a study of complex energy braiding in a one-dimensional non-Hermitian system
with n th-order long-range asymmetrical coupling. Our work highlights the emergence of …

We report the experimental realization of a two-dimensional (2D) weak topological insulator
(WTI) in spinless Su–Schrieffer–Heeger circuits with parity–time and chiral symmetries …
