Black-Hole Signatures in the Finite-Temperature Critical Ising Chain
Zuo Wang, Liang He
We demonstrate that the finite-temperature critical transverse-field Ising chain exhibits quantitative signatures of black-hole physics in its dual gravitational description within…
Suppression of Decoherence at Exceptional Transitions
Mei-Lin Li, Zuo Wang, Liang He
Decoherence is strongly influenced by environmental criticality, with conventional Hermitian critical points typically enhancing the loss of quantum coherence. Here, we show that t…
Emergent non-Hermitian conservation laws at exceptional points
Zuo Wang, Liang He
Non-Hermitian systems can manifest rich static and dynamical properties at their exceptional points (EPs). Here, we identify yet another class of distinct phenomena that is hinged…
Stable excitations and holographic transportation in tensor networks of critical spin chains
Zuo Wang, Liang He
The AdS/CFT correspondence conjectures a duality between quantum gravity theories in anti-de Sitter (AdS) spacetime and conformal field theories (CFTs) on the boundary. One intrigu…
