WebMar 29, 2024 · So topological degeneracy, playing the role of zero-viscosity in superfluid order, implies the existence of a new kind of quantum phase—topologically ordered … WebJul 30, 2013 · Although the topology of a physical system is practically hard to manipulate, recently, it was shown that in certain topologically ordered phases, topological defects can introduce extra topological GSD. Here the topological defects can be viewed as effectively changing the topology of the physical system.
WebConventional topological orders often exhibit ground state degeneracy which is dependent only on the topology of the manifold on which the system is embedded. Fracton models do not have this property, because the ground state degeneracy also depends on system size. WebThe TCI phase is topologically nontrivial in the sense that the bulk state of TCIs cannot be adiabatically transformed to an atomic insulator without breaking the protecting crystal …
WebApr 3, 2014 · In topologically ordered quantum states of matter in 2+1D (space-time dimensions), the braiding statistics of anyonic quasiparticle excitations is a fundamental characterizing property which is directly related to global transformations of the ground-state wavefunctions on a torus (the modular transformations). On the other hand, there … WebJan 22, 2024 · The Harvard researchers then tracked the long-range entanglements that developed between the atoms. In particular, they measured how the quantum correlations …
WebJul 14, 2014 · Distinguishing different topologically ordered phases and characterizing phase transitions between them is a difficult task due to the absence of local order parameters. In this paper, we use a combination of analytical and numerical approaches to distinguish two such phases and characterize a phase transition between them. The …
