Quasiparticle-quasiparticle Scattering in High Tc Superconductors [PDF]

Physica C: Superconductivity, 1999
The quasiparticle lifetime and the related transport relaxation times are the fundamental quantities which must be known in order to obtain a description of the transport properties of the high T_c superconductors.

Origin of switchable quasiparticle-interference chirality in loop-current phase of kagome metals measured by scanning-tunneling-microscopy [PDF]

Nature Communications
In the kagome superconductors AV3Sb5 (A=Cs,Rb,K), a cascade of correlated electron phases cause exotic symmetry-breaking quantum states. In particular, the dissipationless chiral loop-current phase has been attracting increasing attention. A crucial clue

qsGW quasiparticle and GW-BSE excitation energies of 133,885 molecules [PDF]

Scientific Data
Machine learning applications in the chemical sciences, especially when based on neural networks, critically depend on the availability of large quantities of high-quality data. As they provide excellent accuracy for both charged and neutral excitations,

Anisotropic fermionic quasiparticles [PDF]

Physical Review B, 2021
We have carried out a comprehensive investigation of the quasiparticle properties of a two-dimensional electron gas, interacting via the long-range Coulomb interaction, in the presence of bare mass anisotropy (i.e. with an elliptic noninteracting Fermi surface) by calculating the self-energy, the spectral function, the scattering rate, and the ...

Renormalized spectrum of quasiparticle in limited number of states, strongly interacting with two-mode polarization phonons at T=0 K

Condensed Matter Physics, 2021
Within unitary transformed Hamiltonian of Fröhlich type, using the Green's functions method, exact renormalized energy spectrum of quasiparticle strongly interacting with two-mode polarization phonons is obtained at T=0 K in a model of the system with ...

Low-Order Scaling Quasiparticle Self-Consistent GW for Molecules

Frontiers in Chemistry, 2021
Low-order scaling GW implementations for molecules are usually restricted to approximations with diagonal self-energy. Here, we present an all-electron implementation of quasiparticle self-consistent GW for molecular systems.

Many-Body Calculations of Excitons in Two-Dimensional GaN

Crystals, 2023
We present an ab initio study on quasiparticle (QP) excitations and excitonic effects in two-dimensional (2D) GaN based on density-functional theory and many-body perturbation theory.

Beta-decay and structure of odd nuclei, suppression of weak forces in nuclei

Ядерна фізика та енергетика, 2019
Results of calculations in the framework of the dynamic collective model of probabilities of beta-transitions for more than 20 nuclei with mass numbers from А = 31 to А = 231 with one universal renormalization of weak interaction constants are presented.
