Classical and single photon memory devices based on polariton lasers
D. Novokreschenov, A. Kudlis, A. V. Kavokin
Stimulated scattering of incoherent excitons into an exciton-polariton mode leads to the build-up of a polariton condensate whose polarization is sensitive to a small seeded popula…
Quantized topological transport mediated by the long-range couplings
Ekaterina S. Lebedeva, Maxim Mazanov, Alexey V. Kavokin +1
Certain topological systems with time-varying Hamiltonian enable quantized and disorder-robust transport of excitations. Here, we introduce the modification of the celebrated Thoul…
Thermoelectric effects in two-dimensional topological insulators
Z. Z. Alisultanov, E. G. Idrisov, A. V. Kavokin
We explore the nontrivial thermoelectric properties of two-dimensional topological systems. For the Chern insulator, we show that the Seebeck coefficient is fully determined by the…
Anomalous Seebeck effect and counter-propagating ballistic currents in graphene
A. V. Kavokin, S. V. Kavokina, A. A. Varlamov +1
The Seebeck effect consists in the induction of a voltage drop due to the temperature difference in a conductor. In the middle of XIXth century, Lord Kelvin has proposed a relation…
Failure of the Mott's formula for the Thermopower in Carbon Nanotubes
A. V. Kavokin, M. E. Portnoi, A. A. Varlamov +1
Well-known Mott's formula links the thermoelectric power characterised by Seebeck coefficient to conductivity. We calculate analytically the thermoelectric current and Seebeck coef…
