Chiral spin liquids with projected Gaussian fermionic entangled pair states
Sen Niu, Jheng-Wei Li, Ji-Yao Chen +1
We study the parton construction of chiral spin liquids (CSLs) using projected Gaussian fermionic entangled pair states (GfPEPSs). First, we show that GfPEPSs can represent generic…
Chiral spin liquids on the kagome lattice with projected entangled simplex states
Sen Niu, Juraj Hasik, Ji-Yao Chen +1
The infinite projected entangled simplex state (iPESS), a type of tensor network (TN) state, has been used successfully for simulating and characterizing {\it non-chiral} spin liqu…
Static and dynamical signatures of Dzyaloshinskii-Moriya interactions in the Heisenberg model on the kagome lattice
Francesco Ferrari, Sen Niu, Juraj Hasik +3
Motivated by recent experiments on CsCuSnF and YCu(OH)Cl, we consider the Heisenberg model on the kagome lattice with nearest-neighbor su…
Emergent gapless topological Luttinger liquid
Sen Niu, Yucheng Wang, Xiong-Jun Liu
Gapless Luttinger liquid is conventionally viewed as topologically trivial, unless it hosts degenerate ground states and or entanglement spectrum, which necessitates partial bulk d…
Realization of ideal Weyl semimetal band in ultracold quantum gas with 3D Spin-Orbit coupling
Zong-Yao Wang, Xiang-Can Cheng, Bao-Zong Wang +8
The Weyl semimetals [1-6] are three-dimensional (3D) gapless topological phases with Weyl cones in the bulk band, and host massless quasiparticles known as Weyl fermions which were…
Realization and detection of non-ergodic critical phases in optical Raman lattice
Yucheng Wang, Long Zhang, Sen Niu +2
The critical phases, being delocalized but non-ergodic, are fundamental phases which are different from both the many-body localization and ergodic extended quantum phases, and hav…
Emergent topology and symmetry-breaking order in correlated quench dynamics
Long Zhang, Lin Zhang, Ying Hu +2
Quenching a quantum system involves three basic ingredients: the initial phase, the post-quench target phase, and the non-equilibrium dynamics which carries the information of the…
Observation of nodal-line semimetal with ultracold fermions in an optical lattice
Bo Song, Chengdong He, Sen Niu +4
Observation of topological phases beyond two-dimension (2D) has been an open challenge for ultracold atoms. Here, we realize for the first time a 3D spin-orbit coupled nodal-line s…
Magnetic effects on Chern Kondo insulator
Sen Niu, Xiong-Jun Liu
We examine the Chern Kondo insulator proposed in a square optical lattice with staggered flux induced by - orbital hybridization by revisiting its realization and taking into…
Dynamical classification of topological quantum phases
Lin Zhang, Long Zhang, Sen Niu +1
Topological phase of matter is now a mainstream of research in condensed matter physics, of which the classification, synthesis, and detection of topological states have brought ex…
