Polariton-induced transparency in multiple quantum wells probed by time domain Brillouin scattering (2024)
Journal Article
Karzel, M., Samusev, A. K., Linnik, T. L., Littmann, M., Reuter, D., Bayer, M., Scherbakov, A. V., & Akimov, A. V. (2024). Polariton-induced transparency in multiple quantum wells probed by time domain Brillouin scattering. ACS Photonics, 11(12), 5147-5154. https://doi.org/10.1021/acsphotonics.4c01357

The interference of the incident light reflected from the surface of a medium and from a picosecond strain pulse propagating through it results in temporal oscillations of the reflected intensity. This phenomenon, called time-domain Brillouin scatter... Read More about Polariton-induced transparency in multiple quantum wells probed by time domain Brillouin scattering.

Enhanced Photon–Phonon Interaction in WSe2 Acoustic Nanocavities (2024)
Journal Article
Carr, A. D., Ruppert, C., Samusev, A. K., Magnabosco, G., Vogel, N., Linnik, T. L., Rushforth, A. W., Bayer, M., Scherbakov, A. V., & Akimov, A. V. (2024). Enhanced Photon–Phonon Interaction in WSe2 Acoustic Nanocavities. ACS Photonics, 11(3), 1147–1155. https://doi.org/10.1021/acsphotonics.3c01601

Acoustic nanocavities (ANCs) with resonance frequencies much above 1 GHz are prospective to be exploited in sensors and quantum operating devices. Nowadays, acoustic nanocavities fabricated from van der Waals (vdW) nanolayers allow them to exhibit re... Read More about Enhanced Photon–Phonon Interaction in WSe2 Acoustic Nanocavities.

Hybrid coherent control of magnons in a ferromagnetic phononic resonator excited by laser pulses (2024)
Journal Article
Scherbakov, A. V., Carr, A. D., Linnik, T. L., Kukhtaruk, S. M., Armour, A. D., Nadzeyka, A., Rushforth, A. W., Akimov, A. V., & Bayer, M. (2024). Hybrid coherent control of magnons in a ferromagnetic phononic resonator excited by laser pulses. Physical Review Research, 6(1), Article L012019. https://doi.org/10.1103/PhysRevResearch.6.L012019

We propose and demonstrate the concept of hybrid coherent control (CC) whereby a quantum or classical harmonic oscillator is excited by two excitations: one is quasiharmonic (i.e., harmonic with a finite lifetime) and the other is a pulsed broadband...
