What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
Quasiparticleemerges fromBand theoryEstablished
Collective motion acts like a particle.
Mechanism: In a many-body solid, collective excitations behave like particles — quasiparticles with their own mass and charge.
System context
Anyonis aQuasiparticleEstablished
A 2D quasiparticle.
Mechanism: An anyon is a quasiparticle in two dimensions with exchange statistics between bosons and fermions.
Majorana fermionis aQuasiparticleEstablished
Its own antiparticle.
Mechanism: Sought in solids as a zero-energy quasiparticle equal to its own antiparticle, prized for topological qubits.
Plasmonis aQuasiparticleEstablished
An electron-density wave.
Mechanism: A plasmon is the quasiparticle of a collective oscillation in a material's electron sea.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no verified source · no key date stored · 4 of 4 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 4 → 10 → 54 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 4 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
