Charge of a quasiparticle in a superconductor [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance The charge of the quasiparticles in superconductors was never, to our knowledge, directly measured. Here, we used our experience and sensitive techniques in measuring the fractional excitations in the fractional quantum Hall effect via quantum shot noise, to measure the tunneling quasiparticles in a 1D superconductor–insulator ...

Multi-quasiparticle isomers in 174 Lu [PDF]

, 2015
Four-, six-, and eight-quasiparticle isomers with Kπ=14-, (21+) and (26-) have been identified in the deformed nucleus Lu174, in addition to the previously reported Kπ=13+, four-quasiparticle isomeric state.

Physical combinatorics and quasiparticles [PDF]

Journal of Statistical Mechanics: Theory and Experiment, 2009
We consider the physical combinatorics of critical lattice models and their associated conformal field theories arising in the continuum scaling limit. As examples, we consider A-type unitary minimal models and the level-1 sl(2) Wess-Zumino-Witten (WZW) model. The Hamiltonian of the WZW model is the $U_q(sl(2))$ invariant XXX spin chain. For simplicity,

Broken time-reversal symmetry probed by muon spin relaxation in the caged type superconductor Lu5Rh6Sn18 [PDF]

, 2014
The superconducting state of the caged type compound Lu5Rh6Sn18 has been investigated by using magnetization, heat capacity, and muon spin relaxation or rotation (?SR) measurements, and the results interpreted on the basis of the group theoretical ...

Rotation of an Eight-Quasiparticle Isomer [PDF]

Physical Review Letters, 1995
A T-1/2 = 220 ns, eight-quasiparticle isomer, with four unpaired neutrons and four unpaired protons, has been established at an excitation energy of 6576 keV in the prolate deformed nucleus, W-178. The associated rotational band has also been identified, revealing the collective properties in the presence of blocked pairing correlations, with expected ...

Strong reduction of quasiparticle fluctuations in a superconductor due to decoupling of the quasiparticle number and lifetime

, 2021
We measure temperature-dependent quasiparticle fluctuations in a small Al volume, embedded in a NbTiN superconducting microwave resonator. The resonator design allows for readout close to equilibrium.

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.

Quasiparticle properties in effective field theory [PDF]

, 2003
The quasiparticle concept is an important tool for the description of many-body systems. We study the quasiparticle properties for dilute Fermi systems with short-ranged, repulsive interactions using effective field theory.

Quasiparticles and Quasimomentum

, 2006
Common and different properties of particles and quasiparticles are discussed and, in particular, the difference between real and quasimomentum is clarified.
