Flat band fine-tuning and its photonic applications

C Danieli, A Andreanov, D Leykam, S Flach - Nanophotonics, 2024 - degruyter.com
Flat bands–single-particle energy bands–in tight-binding lattices, aka networks, have
attracted attention due to the presence of macroscopic degeneracies and their sensitivity to …

Tight-binding models for SG 143 (P3) and application to recent DFT results on copper-doped lead apatite

MM Hirschmann, J Mitscherling - ar**-induced states at the Fermi level
MM Hirschmann, J Mitscherling - Physical Review Materials, 2024 - APS
Two common difficulties in the design of topological quantum materials are that the desired
features lie too far from the Fermi level and are spread over a too-large energy range …

Multiphoton fusion of light nuclei in intense laser fields

B Wu, Z Fan, D Ye, T Ye, C Gao, C Yu, X Xu, C Zhang… - Physical Review C, 2024 - APS
We investigate the fusion cross sections of light nuclei in the presence of linearly polarized
intense laser fields. By combining the Coulomb-Volkov solutions with the complex spherical …

Quantum engineering for compactly localized states in disordered Lieb lattices

C Danieli, J Liu, RA Römer - The European Physical Journal B, 2024 - Springer
Blending ordering within an uncorrelated disorder potential in families of 3D Lieb lattices
preserves the macroscopic degeneracy of compact localized states and yields …

Non-perturbative dynamics of flat-band systems with correlated disorder

Q Li, J Liu, K Liu, ZX Hu, Z Li - Chinese Physics B, 2024 - iopscience.iop.org
We develop a numerical method for the time evolution of Gaussian wave packets on flat-
band lattices in the presence of correlated disorder. To achieve this, we introduce a method …

Three-charged-particle systems in the framework of coupled coordinate-space few-body equations

RA Sultanov, SK Adhikari - Physical Review C, 2023 - APS
We study three-charged-particle low-energy elastic collision and particle-exchange
reactions with special attention to the systems with Coulomb interaction and an additional …

Interaction-driven Chern insulating phases in the α− T 3 lattice with Rashba spin-orbit coupling

SQ Lin, H Tan, PH Fu, JF Liu - Iscience, 2023 - cell.com
The magnetic interaction is a necessary ingredient to break the time-reversal symmetry in
realizing quantum anomalous Hall, or Chern insulating phases. Here, we study topological …
