Perspective on petahertz electronics and attosecond nanoscopy
J. Schoetz, Z. Wang, E. Pisanty +3
The field of attosecond nanophysics, combining the research areas of attosecond physics with nanoscale physics, has experienced a considerable rise in recent years both experimenta…
Theoretical Atto-nano Physics
Marcelo F. Ciappina, Maciej Lewenstein
Two emerging areas of research, attosecond and nanoscale physics, have recently started to merge. Attosecond physics deals with phenomena occurring when ultrashort laser pulses, wi…
CEP-Controlled Molecular Dissociation by Ultrashort Chirped Laser Pulses
S. A. Karakaş, P. Rosenberger, M. F. Ciappina +2
We demonstrate and characterize that a carrier-envelope-phase (CEP)-controlled ultrashortchirped field is an efficient and robust mechanism to modify the dissociation dynamics of m…
Torsion in quantum field theory through time-loops on Dirac materials
Marcelo F. Ciappina, Alfredo Iorio, Pablo Pais +1
Assuming dislocations could be meaningfully described by torsion, we propose here a scenario based on the role of time in the low-energy regime of two-dimensional Dirac materials,…
High-harmonic generation in solids
Francisco Navarrete, Marcelo F. Ciappina, Uwe Thumm
We analytically and numerically investigate the emission of high-harmonic radiation from model solids by intense few-cycle mid-infrared laser pulses. In single-active-electron appr…
Non-adiabatic ponderomotive effects in photoemission from nanotips in intense mid-infrared laser fields
Johannes Schötz, Sambit Mitra, Harald Fuest +10
Transient near-fields around metallic nanotips drive many applications, including the generation of ultrafast electron pulses and their use in electron microscopy. We have investig…
Extraction of higher-order nonlinear electronic response to strong field excitation in solids using high harmonic generation
Seunghwoi Han, Lisa Ortmann, Hyunwoong Kim +9
State-of-the-art experiments employ strong ultrafast optical fields to study the nonlinear response of electrons in solids on an attosecond time-scale. Notably, a recent experiment…
Spectral Interference in High Harmonic Generation from Solids
Yong Woo Kim, Tian-Jiao Shao, Hyunwoong Kim +5
Various interference effects are known to exist in the process of high harmonic generation (HHG) both at the single atom and macroscopic levels. In particular, the quantum path dif…
