Magnetic phases in the one-dimensional Kondo chain on a metallic surface
Magnetic phases the one-dimensional Kondo chain metallic surface
font style='font-size:12px;'>
2012/2/27
We study the low-temperature properties of a one-dimensional spin-1/2 chain of magnetic impurities coupled to a (normal) metal environment by means of anisotropic Kondo exchange. In the case of easy-p...
Theory of superfluidity and drag force in the one-dimensional Bose gas
Lieb-Liniger model, Tonks-Girardeau gas, Luttinger liquid, drag force, superfluidity, dynamical structure factor
font style='font-size:12px;'>
2011/9/29
The one-dimensional Bose gas is an unusual superfluid. In contrast to higher spatial dimensions, the existence of non-classical rotational inertia is not directly linked to the dissipationless motion ...
Global Stability of Steady Transonic Euler Shocks in Quasi-One-Dimensional Nozzles
