We invite you to our Solid State Physics Seminar.
When: 10 December, Wednesday at 16:30
Where: Lecture hall Beijing-1, Moscow School of Management
What: Heat transport in a hand-made Luttinger liquid
Speaker: Dr. Vadim Khrapai, Institute of Solid State Physics RAS, Chernogolovka and Moscow Institute of Physics and Technology, Dolgoprudny
In a popular-science manner, I will introduce a notion of one-dimensional electronic Luttinger liquid. Unlike in higher-dimensional electronic systems, the energy and momentum conservation laws preclude thermal equilibration in such a system. To my best knowledge, this counter-intuitive prediction was so far not verified experimentally.
In this talk I will present recent experiments  on manipulation of heat flux in an artificial Luttinger liquid, based on counter-propagating quantum Hall edge channels in a two-dimensional system in GaAs. The role of collective excitations and their elastic scattering for the heat transport and equilibration will be discussed.
