For the products of f and g you have f g ( x, y) = ( 0, 0) = g f ( x, y) so also those projectors commute. As an example of a projection that does not commute with f and g we can have: k ( x, y) = ( x, x). Share. Cite.

WebThe existence of commuting projector Hamiltonians for SPTs is important for several reasons. First, it has been proposed that many body localized (MBL)20,21 phases exhibiting SPT order in generic nite energy den-sity eigenstates22{25 can exist only when the SPT in ques-tion has a commuting projector representation26. An odd Z Web1 Consider an inner product space with two projection operators P 1 and P 2. I would like to construct a projection operator P 1 ⊕ P 2 that projects onto the span of the union of the …
WebMar 18, 2024 · We derive several explicit formulae for finding infinitely many solutions of the equation \(AXA=XAX\), when A is singular. We start by splitting the equation into a couple of linear matrix equations and then show how the projectors commuting with A can be used to get families containing an infinite number of solutions. Some techniques for …
WebUsing the decorated domain wall procedure, we construct Finite Depth Local Unitaries (FDLUs) that realize Fermionic Symmetry-Protected Topological (SPT) phases. This results in explicit ‘full’ commuting projector Hamiltonians, where ‘full’ implies the fact that the ground state, as well as all excited state of these Hamiltonians realize the nontrivial SPT … WebAbstract. We introduce a family of commuting-projector Hamiltonians whose degrees of freedom involve Z 3 parafermion zero modes residing in a parent fractional-quantum-Hall fluid. The two simplest models in this family emerge from dressing Ising-paramagnet and toric-code spin models with parafermions; we study their edge properties, anyonic …
WebSep 6, 2024 · 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. The construction starts from a commuting projector model of the topological phase and decorates U(1) charges to the state space in a consistent manner. …
