Project description
Research could boost understanding of collective electron behaviour
The fractional quantum Hall (FQH) effect is a collective behaviour in a 2D system of electrons that is subject to strong magnetic fields and extremely low temperatures. Currently, detailed thermal transport experiments are conducted to probe the properties of FQH edges, which are deemed viable experimental platforms for studying a wide range of quantum phenomena. Despite progress in the field, many questions on edge energy propagation, equilibration and redistribution remain unclear. Funded by the Marie Skłodowska-Curie Actions programme, the TEAPOT project will introduce new observables – heat, mixed and delta-T noise – for probing disordered transport on FQH edges. Project results could increase fundamental understanding of strongly correlated quantum behaviour on the nanoscale.
Objective
In a strong magnetic field and at extremely low temperatures, a two-dimensional sheet of electrons can transition into a strongly correlated state: the fractional quantum Hall (FQH) state. The one-dimensional edge of such a sheet is by itself a viable experimental platform for controlled studies of a wide range of quantum phenomena. Recent experimental developments have enabled detailed thermal transport experiments for probing the properties of such FQH edges. Despite this progress, many questions on edge energy propagation, equilibration, and redistribution remain unanswered. The theoretical TEAPOT project will address these questions by introducing new observables - heat noise, mixed noise and delta-T noise -for disordered transport on general FQH edges. The main goal is to use these promising quantities as novel and complementary tools for probing emergent transport phenomena, not directly or not uniquely related to the electrical charge. TEAPOT will be led by the experienced researcher (ER), as a postdoc project in collaboration with the Supervisor: an expert on quantum thermodynamical processes in nanoscale devices. The ER has recently developed a theoretical model connecting the propagation of charge, heat, and charge noise on general FQH edges. With this substantial preparation, TEAPOT will reach its goal by generating a full theoretical description of the interrelated edge propagation of charge, heat, charge noise, heat noise, delta-T noise, and mixed noise. This description will be derived by the ER and the Supervisor, combining chiral Luttinger liquid techniques with concepts in quantum thermodynamics. TEAPOT will enable novel ways to design and analyze FQH experiments, improving the fundamental understanding of strongly correlated quantum behaviour on the nanoscale. In turn, such an understanding is crucial for the design of novel types of quantum devices, e.g. for small scale thermodynamical or quantum computational applications.
