Static SERS with near-minus-one-epsilon substrate
Alexey P. Vinogradov, Evgeny S. Andrianov
A mechanism for additional enhancement of SERS in the nanoparticle-on-mirror scheme is proposed. This new mechanism is based on the use of a substrate made of material with a near-…
Cascade Brilloiun scattering on short-lived phonons for frequency comb generation
Egor R. Verevkin, Ilya V. Doronin, Alexander A. Zyablovsky +1
We consider Brillouin scattering on short-lived phonon modes, such that the relative Brillouin shift between propagating and scattered waves is smaller than the relative width of p…
Exceptional points of arbitrary high orders induced by non-Markovian dynamics
Timofey T. Sergeev, Evgeny S. Andrianov, Alexander A. Zyablovsky
Exceptional points are singularities in the spectrum of non-Hermitian systems in which several eigenvectors are linearly dependent and their eigenvalues are equal to each other. Us…
All-Optical Brillouin Random number Generator
A. R. Mukhamedyanov, E. S. Andrianov, A. A. Zyablovsky
We propose a model of binary random number generator (RNG) based on a Brillouin optomechanical system. The device uses a hard excitation mode in a Brillouin optomechanical system,…
Non-Markovian protection of states from decay in quasi-PT-symmetric systems
T. T. Sergeev, E. S. Andrianov, A. A. Zyablovsky
We consider a quasi-PT-symmetric system of two resonators, one of which interacts with a finite-size environment. The interaction with the environment leads to energy losses in the…
Thermodynamic coprocessor for linear operations with input-size-independent calculation time based on open quantum system
I. V. Vovchenko, A. A. Zyablovsky, A. A. Pukhov +1
Linear operations, e.g., vector-matrix and vector-vector multiplications, are core operations of modern neural networks. To diminish computational time, these operations are implem…
