Resonantly enhanced terahertz four-wave mixing in fluorides
Eva Noskovicova, Martin Koys, Monika Jerigova +2
Converting a THz signal into the optical domain is of great interest for THz sensing and spectroscopy. Here intense broadband THz pulses with a central frequency of are…
Mid-infrared Kerr index evaluation via cross-phase modulation with a near-infrared probe beam
Dusan Lorenc, Zhanybek Alpichshev
We propose a simple method to measure nonlinear Kerr refractive index in mid-infrared frequency range that avoids using sophisticated infrared detectors. Our approach is based on u…
Bond polarizability as a probe of local crystal fields in hybrid lead-halide perovskites
Yujing Wei, Artem G. Volosniev, Dusan Lorenc +4
A rotating organic cation and a dynamically disordered soft inorganic cage are the hallmark features of hybrid organic-inorganic lead-halide perovskites. Understanding the interpla…
Effective model for studying optical properties of lead-halide perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
We use general symmetry-based arguments to construct an effective model suitable for studying optical properties of lead-halide perovskites. To build the model, we identify an atom…
Spin-Electric Coupling in Lead Halide Perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
Lead-halide perovskites enjoy a number of remarkable optoelectronic properties. To explain their origin, it is necessary to study how electromagnetic fields interact with these sys…
CEP-stable Tunable THz-Emission Originating from Laser-Waveform-Controlled Sub-Cycle Plasma-Electron Bursts
T. Balčiūnas, D. Lorenc, M. Ivanov +9
We study THz-emission from a plasma driven by an incommensurate-frequency two-colour laser field. A semi-classical transient electron current model is derived from a fully quantum-…
