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 ...
Rooted branching bisimulation as a congruence for probabilistic transition systems
(2015)
We propose a probabilistic transition system specification format, referred to as probabilistic RBB safe, for which rooted branching bisimulation is a congruence. The congruence theorem is based on the approach of Fokkink ...
Metric-Space Approach for Distinguishing Quantum Phase Transitions in Spin-Imbalanced Systems
(Springer, 2018-10-01)
Metric spaces are characterized by distances between pairs of elements. Systems that are physically similar are expected to present smaller distances (between their densities, wave functions, and potentials) than systems ...
Structural, electronic, and magnetic entropy contributions of the orbital order-disorder transition in LaMnO(3)
(TAYLOR & FRANCIS LTD, 2011)
Measurements of X-ray diffraction, electrical resistivity, and magnetization are reported across the Jahn-Teller phase transition in LaMnO(3). Using a thermodynamic equation, we obtained the pressure derivative of the ...
Transit reforms in intermediate cities of Colombia: An ex-post evaluation
(Elsevier, 2020)
We use monthly data on transit supply and ridership to evaluate the impact of BRT type reforms in intermediate cities in Colombia. We find that these reforms are associated with a decrease in aggregate transit ridership. ...
Thermal phase transition for some spin-boson models
(2013-09-01)
In this work we study two different spin-boson models. Such models are generalizations of the Dicke model, it means they describe systems of N identical two-level atoms coupled to a single-mode quantized bosonic field, ...
