Solvated electrons in polar liquids as epsilon-near-zero materials tunable in the terahertz frequency range
Matthias Runge, Michael Woerner, Denys I. Bondar +1
Electrons in polar liquids give rise to a polaron resonance at a terahertz (THz) frequency ν_0 depending on electron concentration. The impact of this resonance on light propagatio…
Tuning the terahertz response of liquids by creating polar many-body excitations
Gerard McCaul, Matthias Runge, Michael Woerner +3
A surprising result from the theory of quantum control is the degree to which the properties of a physical system can be manipulated. Both atomic and many-body solid state models a…
Kondo coherence versus superradiance in THz radiation-driven heavy-fermion systems
Chia-Jung Yang, Michael Woerner, Oliver Stockert +4
In strongly correlated systems such as heavy-fermion materials, the coherent superposition of localized and mobile spin states leads to the formation of Kondo resonant states, whic…
Nonlinear terahertz polarizability of electrons solvated in a polar liquid
Matthias Runge, Klaus Reimann, Michael Woerner +1
The nonlinear polaronic response of electrons solvated in liquid 2-propanol is studied by two-dimensional terahertz spectroscopy. Solvated electrons with a concentration of c$_e \a…
Field-Induced Electron Generation in Water: Solvation Dynamics and Many-Body Interactions
Michael Woerner, Benjamin P. Fingerhut, Thomas Elsaesser
The solvated electron represents an elementary quantum system in a liquid environment. Electrons solvated in water have raised strong interest because of their prototypical propert…
Two-Dimensional Terahertz Spectroscopy of Condensed-Phase Molecular Systems
Klaus Reimann, Michael Woerner, Thomas Elsaesser
Nonlinear terahertz (THz) spectroscopy relies on the interaction of matter with few-cycle THz pulses of electric field amplitudes up to megavolts/centimeter (MV/cm). In condensed-p…
Terahertz Polaron Oscillations of Electrons Solvated in Liquid Water
Ahmed Ghalgaoui, Benjamin P. Fingerhut, Klaus Reimann +2
The terahertz (THz) response of solvated electrons in liquid water is studied in nonlinear ultrafast pump-probe experiments. Free electrons with concentrations from c_e = 4 to 140…
Field-Induced Tunneling Ionization and Terahertz-Driven Electron Dynamics in Liquid Water
Ahmed Ghalgaoui, Lisa-Marie Koll, Bernd Schütte +4
Liquid water at ambient temperature displays ultrafast molecular motions and concomitant fluctuations of very strong electric fields originating from the dipolar H2O molecules. We…
Ultrafast spatio-temporal dynamics of terahertz generation by ionizing two-color femtosecond pulses in gases
I. Babushkin, W. Kuehn, C. Koehler +6
We present a combined theoretical and experimental study of spatio-temporal propagation effects in terahertz (THz) generation in gases using two-color ionizing laser pulses. The ob…
Quantum-mechanical wavepacket transport in quantum cascade laser structures
S. -C. Lee, F. Banit, M. Woerner +1
We present a viewpoint of the transport process in quantum cascade laser structures in which spatial transport of charge through the structure is a property of coherent quantum-mec…
