WebSep 7, 2016 · We construct exactly solved commuting projector Hamiltonian lattice models for all known (2+1)-dimensional (2+1D) fermionic symmetry protected topological phases (SPTs) with on-site unitary symmetry group G f = G × Z 2 f, where G is finite and Z 2 f is the fermion parity symmetry. In particular, our models transcend the … WebSep 4, 2024 · By decorating the time-reversal domain walls with spinful Majorana chains, we are able to construct a commuting projector Hamiltonian with zero correlation length ground state wave function that realizes a strongly interacting version of the two-dimensional topological superconductor.
WebSep 23, 2024 · All of the established ansatzes for fixed-point models imply the existence of a gapped boundary as well as a commuting-projector Hamiltonian. Thus, they fail to capture topological phases without a gapped boundary or commuting-projector Hamiltonian, most notably chiral topological phases in 2 + 1 dimensions. In this paper, … WebMar 6, 2024 · Commuting-projector Hamiltonians for chiral topological phases built from parafermions.

Webdefine a local commuting projector Hamiltonian H′ such that every ground state of H′ is a ground state of H, so in this paper we focus on the case of local commuting projector Hamiltonians). Note that for a locally commuting projector Hamiltonian, since each hZ is a projector, the operator norm of hZ is bounded by 1 (indeed, the norm
WebFeb 1, 2024 · We present commuting projector Hamiltonian realizations of a large class of ( 3 + 1 )D topological models based on mathematical objects called unitary G-crossed braided fusion categories. This construction comes with a wealth of examples from the literature of symmetry-enriched topological phases. is the human centipede a true storyWebNow consider the difference between the commuting projector case and the classical case. In the classical case, not only do the individual terms in the Hamiltonian commute, they are all diagonal in a product basis and the ground state of the Hamiltonian is a product state. In the case of commuting projectors, this may not be possible. Indeed, is the humane society the same as aspcaWebJan 31, 2024 · We also show that for any local commuting projector Hamiltonian, the relative chiral central charge vanishes, while for free fermionic systems, it is related to the zero-temperature electric Hall conductance via the Wiedemann-Franz law.
