Many-Body effects beyond excitons in second-harmonic generation of monolayer MoS
Peio Garcia-Goiricelaya, Julen Ibañez-Azpiroz
We present a quantitative study of many-body effects including the three-particle level on second-harmonic generation in monolayer MoS. Our approach combines many-body perturba…
Surface-state engineering for nonlinear charge and spin photocurrent generation
Javier Sivianes, Peio Garcia-Goiricelaya, Daniel Hernangómez-Pérez +1
We systematically explore a pathway for generating nonlinear charge and spin photocurrents using spin-orbit-split surface states. This mechanism enables net charge and spin flow al…
Understanding the large shift photocurrent of WS nanotubes: A comparative analysis with monolayers
Jyoti Krishna, Peio Garcia-Goiricelaya, Fernando de Juan +1
We study the similarities and differences in the shift photocurrent contribution to the bulk photovoltaic effect between transition-metal dichalcogenide monolayers and nanotubes. O…
Ab initio study of the structural, vibrational and optical properties of potential parent structures of nitrogen-doped lutetium hydride
Đorđe Dangić, Peio Garcia-Goiricelaya, Yue-Wen Fang +2
The recent report of near-ambient conditions superconductivity in a nitrogen-doped lutetium hydride has inspired a large number of experimental studies with contradictory results.…
Including many-body effects into the Wannier-interpolated quadratic photoresponse tensor
Peio Garcia-Goiricelaya, Jyoti Krishna, Julen Ibañez-Azpiroz
We present a first-principles scheme for incorporating many-body interactions into the unified description of the quadratic optical response to light of noncentrosymmetric crystals…
Electron-phonon coupling of Fe-adatom electron states on MgO/Ag(100)
Haritz Garai-Marin, Julen Ibañez-Azpiroz, Peio Garcia-Goiricelaya +2
We study the strength of the electron-phonon interaction on Fe single adatoms on MgO/Ag(100) based on many-body \textit{ab-initio} spin collinear calculations. In particular, we an…
Emergence of large non-adiabatic effects induced by the electron-phonon interaction on the complex vibrational quasi-particle spectrum of the doped monolayer MoS
Peio Garcia-Goiricelaya, Jon Lafuente-Bartolome, Idoia G. Gurtubay +1
We present a comprehensive first-principles analysis of the non-adiabatic effects due to the electron-phonon interaction on the vibrational spectrum of the electron-doped monolayer…
Long living carriers in a strong electron-phonon interacting two-dimensional doped semiconductor
Peio Garcia-Goiricelaya, Jon Lafuente-Bartolome, Idoia G. Gurtubay +1
Carrier doping by the electric field effect has emerged recently as an ideal route for monitoring many-body physics in two-dimensional (2D) materials where the Fermi level is tuned…
Coupled spin and electron-phonon dynamics at the relativistic Tl/Si(111) surface
Peio Garcia-Goiricelaya, Idoia G. Gurtubay, Asier Eiguren
We investigate the role played by the electron spin and the spin-orbit interaction on the exceptional electronphonon coupling at the Tl/Si(111) surface. Our first-principles calcul…
