Landau quantization and quasiparticle interference in the three-dimensional Dirac semimetal Cd₃As₂.
Nature Materials, 2014Condensed-matter systems provide a rich setting to realize Dirac and Majorana fermionic excitations as well as the possibility to manipulate them for potential applications.

Origins of Heavy Quasiparticles
2002Two new microscopic models for the appearance of heavy quasiparticles have been recently suggested. They concern UPt3 and LiV2O4 and are based on a partial localization of 5f electrons and on geometrical frustrations, respectively.

AIP Conference Proceedings, 2005
We show how calculate the energies and the widths of quasiparticle resonant states without solving the complex bcs equations. The method is based on BCS equations solved in the real representation including the continuum. In this representation the quasiparticle resonances are associated to the Gamow states of the mean field.

Fractionally charged quasiparticles
Physica E: Low-dimensional Systems and Nanostructures, 2003Fractionally charged quasiparticles were proposed by Laughlin to explain the fractional quantum Hall effect. Flowing in one-dimensional-like strips along the edges of the sample the quasiparticles are expected to condenseto a chiral Luttinger liquid (CLL).

Quasiparticle Electronic Structures
2014The energy positions of the main peaks in the spectral functions of inhomogeneous electron gases represent their quasiparticle electronic structures. Discussing numerical results based on ab initio Kohn-Sham and generalized Kohn-Sham starting electronic structures the great success of the Hedin GW approximation to the exchange-correlation energy is ...

Quasiparticles in Leptogenesis
2011We analyse the effects of thermal quasiparticles in leptogenesis using hard-thermal-loop-resummed propagators in the imaginary time formalism of thermal field theory. We perform our analysis in a leptogenesis toy model with three right-handed heavy neutrinos N_1, N_2 and N_3.
