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

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
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
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
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
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
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
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.
