A1 Coherent spin manipulation in quantum dot ensembles: Tailoring of spin dynamics and interactions

Principal investigators:

Associated: Dr. Philipp Grigoryev, Dr. Vasilii Belykh and PhD student Nataliya Kopteva

Summary:

The project focuses on tailoring the precession of spins in a quantum dot ensemble and exploring the interactions between different spin ensembles. The variability provided by a spin ensemble shall be exploited to generate and study spin mode distributions with complex dynamics. Furthermore, based on a microscopic understanding of the spin-spin interaction, we plan to optimize the interaction strength for obtaining spin states with robust entanglement. Based on these methods, tools for coherent manipulation of interacting and entangled spin states shall be worked out, for which also the potential of dynamic decoupling tools will be elaborated.

 

The project is supported from Russian side by the RFBR, project No. 15-52-12019. The project leader is Irina Yugova.

A3 Transient four-wave mixing with spins

Principal investigators:

Associated: Dr. Marina Semina and Prof. Dr. Robert Suris (Ioffe Institute) as well as Dr. Irina Yugova (St. Petersburg State University) and PhD student Ivan Solov’ev

Summary:

The project focuses on photon echo phenomena involving semiconductor nanostructures (quantum wells and quantum dots) with localized resident carriers subject to external magnetic fields. The goal is to combine optical and spin excitations in an inhomogeneously broadened system to realize long-lived optical quantum memories. The interaction of resonant optical pulses with fundamental optical excitations such as excitons or trions with well-defined spin level structure will be explored. Stimulated and spontaneous photon echoes will be analyzed using transient four-wave mixing with heterodyne detection.

A5 Spin noise through bath coupling

Principal investigators:

Associated: Prof. Dr. Evgueni Alexandrov (Ioffe Institute) and Dr. Ivan Ryzhov (St. Petersburg State University)

Summary:

This project is aimed to study the influence of external perturbations on spin systems in thermal equilibrium by the spin noise methodology. We want to provide comparative studies of unperturbed vs. perturbed spin systems, for which the perturbations are provided either by optical illumination or by radio-frequency fields influencing the nuclear surrounding of localized carriers. Furthermore, we plan to develop cavity-enhanced spin noise spectroscopy and apply it to different spin systems with the goal to detect magnetic resonances and study the dynamics of spins through higher order correlations.

A6 Understanding the nuclear spin bath impact on spin coherence

Principal investigators:

Associated: Dr. Roman Cherbunin, Dr. Maria Kusnetzova, Dr. Mikhail Petrov and Prof. Dr. Sergey Verbin (St. Petersburg State University) as well as Dr. Vladimir Kalevich (Ioffe Institute)

Summary:

This project investigates nuclear spin fluctuations, effects of quadrupole splitting of nuclear spin states, spin-lattice relaxation and decoherence in the nuclear spin system of semiconductors. For this purpose, the nuclear spin polarization will be enhanced by dynamic polarization via spin-oriented electrons. Optically detected magnetic resonance will be used to determine the evolution of the nuclear spins in magnetic fields and their back-action on the central electron spin of a localized charge carrier. The role of quadrupole splittings of nuclear spin states, which may considerably affect the nuclear-nuclear and electron-nuclear spin dynamics and carrier spin coherence, will also be studied.

B7 Spin-dependent polariton condensates

Principal investigators:

Associated: Dr. Mikhail Petrov, Dr. Artur Trifonov and PhD student Andrey Kurdyubov (St. Petersburg State University)

Summary:

This project is focused on using the spin-anisotropic polariton-polariton interaction to create spin-sensitive all-optical circuit-like switches or other logical elements. Thus, we will utilize spin as an additional degree of freedom in optical information processing. The concept of “polariton neurons” as proposed by us as building blocks of polariton integrated circuits will be checked experimentally. We will demonstrate basic polariton logic elements, thereby paving the way towards spin-sensitive optical circuits that are also inscribed optically and can therefore be created and modified on demand.
