Evolution of terahertz third harmonic response across rare-earth nickelate phase-diagram
Gulloo Lal Prajapati, Igor Ilyakov, Alexey Ponomaryov +8
High harmonic generation (HHG) is a sensitive probe for investigating electronic structures and dynamics of materials and a source for attosecond pulses. In particular, HHG with te…
Higher harmonics in Mott-Hubbard insulators as sensors
Abdelrahman Azab, Friedemann Queisser, Gulloo Lal Prajapati +2
Using strong-coupling time-dependent perturbation theory, we study the response of Mott and charge-transfer insulators to an oscillating electric field. We derive analytical expres…
Plasmonic metamaterial time crystal
Tingwen Guo, Jules Sueiro, Gian Marcello Andolina +18
Periodically driven optical materials and metamaterials have recently emerged as a promising platform for realizing photonic time crystals (PTCs), which are systems whose optical p…
Biological Crowding Annihilates Terahertz Transmission Nonlinearity in Aqueous Protein Solutions
Ellen M. Adams, Igor Ilyakov, Manthan Raj +6
Hydration water is vital for the stabilization of protein structure and function. The strong interaction of hydration water with the protein surface brings into question how dynami…
Terahertz-driven ultrafast dynamics of rare-earth nickelates by controlling only the charge degree of freedom
Gulloo Lal Prajapati, Sergey Kovalev, Igor Ilyakov +5
An important strategy for understanding the microscopic physics of strongly correlated systems and enhancing their technological potential is to selectively drive the fundamental d…
Highly efficient broadband THz upconversion with Dirac materials
Tatiana A. Uaman Svetikova, Igor Ilyakov, Alexey Ponomaryov +16
The use of the THz frequency domain in future network generations offers an unparalleled level of capacity, which can enhance innovative applications in wireless communication, ana…
Terahertz harmonic generation across the Mott insulator-metal transition
Gulloo Lal Prajapati, Sujay Ray, Igor Ilyakov +8
We demonstrate terahertz (THz) harmonic generation across the Mott insulator-metal transition in rare-earth nickelates (RNiO, R = rare-earth atom). The THz harmonic generation…
THz Second and Third Harmonic Generation in PdCoO Thin Films
T. Priessnitz, L. Feng, T. V. A. G. de Oliveira +9
Terahertz high harmonic generation (THz HHG) is a common property of nonlinear systems. Recently it has been used to investigate fundamental principles that govern transport and no…
Ultrafast unidirectional spin Hall magnetoresistance driven by terahertz light field
Ruslan Salikhov, Igor Ilyakov, Anneke Reinold +11
The ultrafast control of magnetisation states in magnetically ordered systems is a key technological challenge for developing memory devices operable at picosecond timescales or te…
Spin-orbit interaction driven terahertz nonlinear dynamics in transition metals
Ruslan Salikhov, Markus Lysne, Philipp Werner +15
The interplay of electric charge, spin, and orbital polarizations, coherently driven by picosecond long oscillations of light fields in spin-orbit coupled systems, is the foundatio…
Tunable room temperature nonlinear Hall effect from the surfaces of elementary bismuth thin films
Pavlo Makushko, Sergey Kovalev, Yevhen Zabila +13
The nonlinear Hall effect (NLHE) with time-reversal symmetry constitutes the appearance of a transverse voltage quadratic in the applied electric field. It is a second-order electr…
