Realizing quantum optics in structured environments with giant atoms
Xin Wang, Huai-Bing Zhu, Tao Liu +1
To go beyond quantum optics in free-space setups, atom-light interfaces with structured photonic environments are often employed to realize unconventional quantum electrodynamics (…
The suppression of Finite Size Effect within a Few Lattices
Tao Liu, Kai Bai, Yicheng Zhang +4
Boundary modes localized on the boundaries of a finite-size lattice experience a finite size effect (FSE) that could result in unwanted couplings, crosstalks and formation of gaps…
Multipartite entanglement of the topologically ordered state in a perturbed toric code
Yu-Ran Zhang, Yu Zeng, Tao Liu +3
We demonstrate that multipartite entanglement, witnessed by the quantum Fisher information (QFI), can characterize topological quantum phase transitions in the spin- t…
Observation of Square-Root Higher-Order Topological States in Photonic Waveguide Arrays
Juan Kang, Tao Liu, Mou Yan +7
Recently, high-order topological insulators (HOTIs), accompanied by topologically nontrivial boundary states with codimension larger than one, have been extensively explored becaus…
Unconventional quantum sound-matter interactions in spin-optomechanical-crystal hybrid systems
Xing-Liang Dong, Peng-Bo Li, Tao Liu +1
We predict a set of unusual quantum acoustic phenomena resulting from sound-matter interactions in a fully tunable solid-state platform, in which an array of solid-state spins in d…
Higher-Order Weyl-Exceptional-Ring Semimetals
Tao Liu, James Jun He, Zhongmin Yang +1
For first-order topological semimetals, non-Hermitian perturbations can drive the Weyl nodes into Weyl exceptional rings having multiple topological structures and no Hermitian cou…
Tunable Chiral Bound States with Giant Atoms
Xin Wang, Tao Liu, Anton Frisk Kockum +2
We propose tunable chiral bound states in a system composed of superconducting giant atoms and a Josephson photonic-crystal waveguide (PCW), with no analog in other quantum setups.…
Topological quantum phase transitions retrieved through unsupervised machine learning
Yanming Che, Clemens Gneiting, Tao Liu +1
The discovery of topological features of quantum states plays an important role in modern condensed matter physics and various artificial systems. Due to the absence of local order…
Non-Hermitian topological Mott insulators in one-dimensional fermionic superlattices
Tao Liu, James Jun He, Tsuneya Yoshida +2
We study interaction-induced Mott insulators, and their topological properties in a 1D non-Hermitian strongly-correlated spinful fermionic superlattice system with either nonrecipr…
Topological band theory for non-Hermitian systems from the Dirac equation
Zi-Yong Ge, Yu-Ran Zhang, Tao Liu +3
We identify and investigate two classes of non-Hermitian systems, i.e., one resulting from Lorentz-symmetry violation (LSV) and the other from a complex mass (CM) with Lorentz inva…
Second-Order Topological Phases in Non-Hermitian Systems
Tao Liu, Yu-Ran Zhang, Qing Ai +4
A -dimensional second-order topological insulator (SOTI) can host topologically protected -dimensional gapless boundary modes. Here we show that a 2D non-Hermitian SOTI…
Broad-Band Negative Refraction via Simultaneous Multi-Electron Transitions
Jing-Jing Cheng, Ying-Qi Chu, Tao Liu +4
We analyze different factors which influence the negative refraction in solids and multi-atom molecules. We find that this negative refraction is significantly influenced by simult…
Majorana corner states in a two-dimensional magnetic topological insulator on a high-temperature superconductor
Tao Liu, James Jun He, Franco Nori
Conventional -dimensional topological superconductors (TSCs) have protected gapless -dimensional boundary states. In contrast to this, second-order TSCs are characteriz…
