Tamm plasmon-polaritons: Possible electromagnetic states at the interface of a metal and a dielectric Bragg mirror
Conventional surface plasmons have a wave vector exceeding that of light in vacuum, and therefore cannot be directly excited by light that is simply incident on the surface. However, we propose that…

Optical circuits based on polariton neurons in semiconductor microcavities.
TLDR
By exploiting the polarization multistability of polaritons, it is shown that polarized signals can be conducted in the plane of a semiconductor microcavity along controlled channels or "neurons" and it is possible to realize binary logic gates operating on the polarization degree of freedom.

Polarization multistability of cavity polaritons.
New effects of polarization multistability and polarization hysteresis in a coherently driven polariton system in a semiconductor microcavity are predicted and theoretically analyzed. The…

Spin-dependent zero-bias peak in a hybrid nanowire-quantum dot system: Distinguishing isolated Majorana fermions from Andreev bound states
Hybrid system composed by a semiconducting nanowire with proximity-induced superconductivity and a quantum dot at the end working as spectrometer was recently used to quantify the so-called degree of…

Quantum theory of spin dynamics of exciton-polaritons in microcavities.
TLDR
It is shown that giant longitudinal-transverse splitting of the polaritons mixes their spin states, which results in beats between right- and left-circularly polarized photoluminescence of microcavities, as was recently experimentally observed.

Lossless interface modes at the boundary between two periodic dielectric structures
Tamm states of light are lossless interface modes decaying exponentially in the surrounding media. We show that they can be formed at the boundary between two periodical dielectric structures, one…

An electrically pumped polariton laser
Conventional semiconductor laser emission relies on stimulated emission of photons, which sets stringent requirements on the minimum amount of energy necessary for its operation. In comparison,…

Hybrid states of Tamm plasmons and exciton polaritons
Channeling of exciton polaritons in the plane of semiconductor microcavities can be achieved by the deposition of metallic mesas on the top of the semiconductor structure. We show theoretically that…

Exciton-exciton interaction in transition-metal dichalcogenide monolayers
We study theoretically the Coulomb interaction between excitons in transition metal dichalcogenide (TMD) monolayers. We calculate direct and exchange interaction for both ground and excited states of…
