Chiral symmetry condensed matter
WebIn condensed matter physics, chiral symmetry is realized by sublattice symmetry (see early work in Ref. ) or as a combination of time reversal and particle-hole symmetry . In the terminology of condensed matter physics, the winding number comes in as characterization of translationally invariant one-dimensional chiral systems that are …

WebApr 13, 2024 · Chirality is a very active field of research in organic chemistry, closely linked to the concept of symmetry. Topology, a well-established concept in mathematics, has nowadays become essential to describe condensed matter. At its core are chiral electron states on the bulk, surfaces and edges of the condensed matter systems, in which spin … WebSymmetries can forbid all relevant operators that would lift gapless modes that are not Goldstones. An example is chiral symmetry in QCD, which forbids fermion masses. A …
WebIn condensed matter physics, chiral symmetry breaking in materials plays an essential role in stabilizing a macroscopic ordered state with a left- or right-handed incommensurate (IC) twist of multicomponent order parameters. This kind of IC state accommodates topological discommensuration (DC). WebDec 7, 2024 · Here we show that the generalized time-reversal, particle-hole, and chiral symmetry operators consistently explain not only the symmetry transformation properties between the ground states but also the topological features of the topological solitons in prototypical quasi-1D systems such as the SSH, Rice-Mele, and double-chain models.
