Symmetry-protected intermediate trivial phases in quantum spin chains
Augustine Kshetrimayum, Hong-Hao Tu, Roman Orus
Symmetry-protected trivial (SPt) phases of matter are the product-state analogue of symmetry-protected topological (SPT) phases. This means, SPt phases can be adiabatically connect…
Edge states for the Kalmeyer-Laughlin wave function
Benedikt Herwerth, Germán Sierra, Hong-Hao Tu +2
We study lattice wave functions obtained from the SU(2) Wess-Zumino-Witten conformal field theory. Following Moore and Read's construction, the Kalmeyer-Laughlin fractional qua…
Non-Abelian Chiral Spin Liquid on the Kagome Lattice
Zheng-Xin Liu, Hong-Hao Tu, Ying-Hai Wu +4
We study spin liquid states on the kagome lattice constructed by Gutzwiller-projected superconductors. We show that the obtained spin liquids are either non-Abelia…
Methods for detecting charge fractionalization and winding numbers in an interacting fermionic ladder
Leonardo Mazza, Monika Aidelsburger, Hong-Hao Tu +2
We consider a spin-1/2 fermionic ladder with spin-orbit coupling and a perpendicular magnetic field, which shares important similarities with topological superconducting wires. We…
Cosmological Perturbations and Quasi-Static Assumption in Theories
Mu-Chen Chiu, Andy Taylor, Chenggang Shu +1
gravity is one of the simplest theories of modified gravity to explain the accelerated cosmic expansion. Although it is usually assumed that the quasi-Newtonian approach (a…
Infinite matrix product states, boundary conformal field theory, and the open Haldane-Shastry model
Hong-Hao Tu, Germán Sierra
We show that infinite Matrix Product States (MPS) constructed from conformal field theories can describe ground states of one-dimensional critical systems with open boundary condit…
