Phenomenon that occurs when a microscopically complicated system (such as a solid) behaves as if it contained different weakly interacting particles in free space.
A key example is a quantum crystal composed of coherent superpositions of different, spatially ordered configurations of collectiveexcitations.

1
The critical fluctuations responsible for the enhancement of the quasiparticle masses appear to weaken the superconducting state.
2
This is the first observation of a three-quasiparticle chiral structure and establishes the primarily geometric nature of this phenomenon.
3
Quantum oscillations of the magnetostriction allow identifying the band-specific quasiparticle masses which by far exceed the band-structure derived masses.
4
This shrinking is accompanied by a strong increase in the quasiparticle effective mass as x is tuned toward the maximum T{c}.
5
In the usual case where both spin-orbit split bands are occupied, the intrinsic spin-Hall conductivity has a universal value for zero quasiparticle spectral broadening.
6
The dimensionless ratio of the Seebeck coefficient to the electronic specific heat shows a minimum at a temperature close to threshold of the quasiparticle formation.
7
A fitting analysis identifies clear anomalies at Tp=7.5 K in the temperature dependencies of the superconducting gap size and the quasiparticle relaxation lifetime.
8
A low quasiparticle density of states at low energies with a multiband Fermi-surface topology would open a new door into electron pairing in CeCu2Si2.
9
This contrasting behavior reveals the presence of uncondensed electrons coexisting with nodal quasiparticles.
10
The known quasiparticles tend to act like heavier versions of electrons, but not so in this case.
11
Interactions between electrons create wavelike disturbances-knownas quasiparticles-thatserve as the basic components of almost every complex material.
