Unveiling Correlated Two-dimensional Topological Insulators through Fermionic Tensor Network States -- Classification, Edge Theories and Variational Wavefunctions
Chao Xu, Yixin Ma, Shenghan Jiang
The study of topological band insulators has revealed fascinating phases characterized by band topology indices and anomalous boundary modes protected by global symmetries. In stro…
Coexisting and interacting spin torque driven free and reference layer magnetic droplet solitons
Sheng Jiang, Sunjae Chung, Martina Ahlberg +6
Magnetic droplets are nanoscale, non-topological, magnetodynamical solitons that can be nucleated in spin torque nano-oscillators (STNOs) or spin Hall nano-oscillators (SHNOs). All…
Variational Tensor Wavefunctions for the Interacting Quantum Spin Hall Phase
Yixin Ma, Shenghan Jiang, Chao Xu
The quantum spin hall (QSH) phase, also known as the 2D topological insulator, is characterized by protected helical edge modes arising from time reversal symmetry. While initially…
Flipping of antiferromagnetic to superconducting states in pressurized quasi-one-dimensional manganese-based compounds
Sijin Long, Long Chen, Yuxin Wang +10
One of the universal features of unconventional superconductors is that the superconducting (SC) state is developed in the proximity of an antiferromagnetic (AFM) state. Understand…
Exactly solvable models for U(1) symmetry-enriched topological phases
Qing-Rui Wang, Meng Cheng
We propose a general construction of commuting projector lattice models for 2D and 3D topological phases enriched by U(1) symmetry, with finite-dimensional Hilbert space per site.…

Shenghan Jiang, Meng Cheng, Yang Qi +1
We propose and prove a family of generalized Lieb-Schultz-Mattis (LSM) theorems for symmetry protected topological (SPT) phases on boson/spin models in any dimensions. The "convent…

Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich
We perform a numerical study of a spin-1/2 model with symmetry in one dimension which demonstrates an interesting similarity to the physics of tw…

Shenghan Jiang, Olexei I. Motrunich
We study a one-dimensional (1d) system that shows many analogies to proposed two-dimensional (2d) deconfined quantum critical points (DQCP). Our system is a translationally invaria…
Dyonic Lieb-Shultz-Mattis Theorem and Symmetry Protected Topological Phases in Decorated Dimer Models
Xu Yang, Shenghan Jiang, Ashvin Vishwanath +1
We consider 2+1D lattice models of interacting bosons or spins, with both magnetic flux and fractional spin in the unit cell. We propose and prove a modified Lieb-Shultz Mattis (LS…
Anyon condensation and a generic tensor-network construction for symmetry protected topological phases
Shenghan Jiang, Ying Ran
We present systematic constructions of tensor-network wavefunctions for bosonic symmetry protected topological (SPT) phases respecting both onsite and spatial symmetries. From the…

The properties of ground state of spin- kagome antiferromagnetic Heisenberg (KAFH) model have attracted considerable interest in the past few decades, and recent numer…
