Phonon traps reduce the quasiparticle density in superconducting circuits [PDF]

Applied Physics Letters, 2019
Out of equilibrium quasiparticles (QPs) are one of the main sources of decoherence in superconducting quantum circuits, and are particularly detrimental in devices with high kinetic inductance, such as high impedance resonators, qubits, and detectors ...

Tomographic mapping of the hidden dimension in quasi-particle interference

Nature Communications, 2021
Quasiparticle interference is a powerful tool for characterization of electronic structure which leverages scattering off defects; however, it is limited to quasi two-dimensional materials.

Condensing Non-Abelian Quasiparticles [PDF]

Physical Review Letters, 2010
A most interesting feature of certain fractional quantum Hall states is that their quasiparticles obey non-Abelian fractional statistics. So far, candidate non-Abelian wave functions have been constructed from conformal blocks in cleverly chosen conformal field theories.

Anomalous Ferromagnetism of quasiparticle doped holes in cuprate heterostructures revealed using resonant soft X-ray magnetic scattering

Nature Communications, 2022
Long-range magnetic order of quasiparticle doped holes is important for understanding the physics of cuprate superconductors, albeit difficult to probe in experiments. Ong et al.

Quasiparticle engineering and entanglement propagation in a quantum many-body system [PDF]

Nature, 2014
The key to explaining and controlling a range of quantum phenomena is to study how information propagates around many-body systems. Quantum dynamics can be described by particle-like carriers of information that emerge in the collective behaviour of the ...

Method of successive separation and summing of multiplicative diagrams of mass operator for the multi-level quasiparticle interacting with polarization phonons

Condensed Matter Physics, 2019
The theory of renormalized energy spectrum of a multi-level quasiparticle interacting with polarization phonons at T = 0 K is developed within the Feynman-Pines diagram technique in a new approach.

Entanglement Content of Quasiparticle Excitations. [PDF]

Physical Review Letters, 2018
We investigate the quantum entanglement content of quasiparticle excitations in extended many-body systems. We show that such excitations give an additive contribution to the bipartite von Neumann and Rényi entanglement entropies that takes a simple ...

Properties of color-flavor locked matter in a quasiparticle model

European Physical Journal C: Particles and Fields, 2023
We investigate the thermodynamical properties of color-flavor locked (CFL) quark matter at zero temperature, finite temperature, and strong magnetic field by using quasiparticle model. We find that considering CFL quark phase can significantly change the

Quasiparticle tunneling and quasiparticle-pair interference in granular superconductors

Physical Review B, 1991
Calcul du diagramme des phases d'un tableau de Jonctions Josephson presentant un effet tunnel des quasi-particules, en prenant en compte le terme d'interference des paires de quasi-particules (QPPI). En plus du fait qu'elle introduit des effets de renormalisation interessant dans le terme Josephson, la QPPI deplace la resistance critique.

Interference measurements of non-Abelian e/4 & Abelian e/2 quasiparticle braiding [PDF]

, 2019
The quantum Hall states at filling factors 5/2 and 7/2 are expected to have Abelian charge e/2 quasiparticles and non-Abelian charge e/4 quasiparticles.
