Local sustainable diets as a driver of the transition to agroecological food systems
(Ohann Heinrich Von Thunen Inst-Vti, 2020)
In this paper, we propose the promotion of local sustainable diets as a process that can facilitate the transition of current industrialised food systems to agroecological food systems. First, we describe the problem, which ...
Q-deformed fermionic Lipkin model at finite temperature
(1997-08-15)
The interplay between temperature and q-deformation in the phase transition properties of many-body systems is studied in the particular framework of the collective q-deformed fermionic Lipkin model. It is shown that in ...
Nonequilibrium quantum phase transitions in the XY model: comparison of unitary time evolution and reduced density operator approaches
(IOP Publishing, 2014)
We study nonequilibrium quantum phase transitions in the XY spin 1/2 chain
using the C* algebra. We show that the well-known quantum phase transition at
a magnetic field of h = 1 also persists in the nonequilibrium setting ...
