About

Outline Quantum Electrodynamics with 2D materials

[supervisors: prof. dr hab. Ireneusz Grabowski, NCU/prof. Carsten Rockstuhl, Karlsruhe Institute of Technology/dr Karolina Słowik, NCU].

Research scope and expected impact

Two-dimensional materials (e.g. graphene, hexagonal boron nitride, transition-metal

dichalcogenides), offer a unique opportunity to design their optical properties by tuning them with electric, optical or chemical means or by combining them among each other. In consequence, their optical response may span a broad region of the electromagnetic spectrum, ranging from microwave to ultraviolet wavelengths. One particularly appealing feature is the ability of 2D materials to support strongly confined electromagnetic modes, whose length scales range from microns down to a few nanometers. The confinement is accompanied by local field intensity enhancement, which unlocks the possibility to achieve extraordinarily strong interactions with atomic systems (atoms, molecules) which might be positioned in the focal volume.

The scope of this project is to exploit tunable two-dimensional materials to tailor light-matter interactions at the nanoscale. Coupling strength, emission properties, spectral properties, nonlinear interactions in addition to a dynamic control of material properties enables multiple applications for signal processing at the quantum level, construction of new types of quantum logic gates, generation of multiphoton nonclassical states of light, or coupling of atomic systems that could be activated on demand. In this project we aim to lay down the ground for such devices, to be based on atomic systems coupled to nanostructures made of 2D materials.

The project will be carried out in collaboration with Prof. Carsten Rockstuhl, Karlsruhe Institute of Technology,Germany, expertize area: nanophotonics Prof. Andres Ayuela, Donostia International Physics Center, San Sebastian, Spain, expertize area: solid state theory, 2D materials Supervisors in Toruń: many-body physics, quantum optics

Methods

2D materials (finite flakes, extended ribbons, etc.) will be described with the quantum tight-binding Hamiltonian. Modeling of light-matter interactions will exploit self-consistent potential based on the dipolar coupling scheme. Dynamics of the system will be described with a master equation.

The group has developed Python codes to model dynamics of graphene subject to electromagnetic radiation. Extensions to include other materials quantized fields will need to be implemented by the student.
