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

open access: yesNature 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]

open access: yesScientific 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,

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

open access: yesCondensed 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

open access: yesFrontiers 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

open access: yesCrystals, 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

open access: yesЯдерна 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.

Towards Deep Integration of Electronics and Photonics

open access: yesApplied Sciences, 2019
A combination of computational power provided by modern MOSFET-based devices with light assisted wideband communication at the nanoscale can bring electronic technologies to the next level. Obvious obstacles include a size mismatch between electronic and

Temperature dependence of quasiparticle interference in $d$-wave superconductors

open access: yesSciPost Physics Core, 2023
We investigate the temperature dependence of quasiparticle interference in the high $T_c$-cuprates using an exact-diagonalization + Monte-Carlo based scheme to simulate the $d$-wave superconducting order parameter. The quasiparticle interference patterns

Tomographic mapping of the hidden dimension in quasi-particle interference

open access: yesNature 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.

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

open access: yesNature 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.
