Webnontrivial topology arise due to the coupling of these external elds with the baryon chemical potential via the chiral anomaly. Recently, there has been a challenging new idea that the ground state of dense QCD matter in the presence of a strong magnetic eld could be the chiral soliton lattice (CSL) made of bosonic neutral pion ˇ0 instead of WebApr 30, 2024 · I don't know much about topology, but the other day I was thinking about the (classic?) coffee cup - donut topological equivalence. I realised that a cylinder with one open end and a handle on the side (a mug) is a chiral object in 3D space, whereas a torus/donut is achiral ("meso", as indicated by the internal planes of symmetry present in a torus).

While for a general 1D band structure this phase may take arbitrary values, it is integer (i.e. Z) quantized (in units of π) [37] when chiral symmetry is present, and Z2 quantized for the SSH case.
