Thermalization of field driven quantum systems [PDF]
There is much interest in how quantum systems thermalize after a sudden change, because unitary evolution should preclude thermalization. The eigenstate thermalization hypothesis resolves this because all observables for quantum states in a small energy window have essentially the same value; it is violated for integrable systems due to the infinite ...

The hidden geometry of MUSAC. Field systems as the origin of form in the contemporary project
The origin of the contemporary project’s form has become an enigma. The process of drawing up a project ends up being a superimposed, diluted reality, hidden by the narratives constructed by their authors. At some point, in which the process becomes more

Resumen El origen de la forma en el proyecto contemporáneo se ha convertido en un enigma. La realidad del proceso del proyecto queda superpuesta, diluida y oculta por las narrativas construidas, posteriormente, por sus autores.

Topological Field Theory of Non-Hermitian Systems [PDF]
Non-Hermiticity gives rise to unique topological phases without Hermitian analogs. However, the effective field theory has yet to be established. Here, we develop a field-theoretical description of the intrinsic non-Hermitian topological phases. Because of the dissipative and nonequilibrium nature of non-Hermiticity, our theory is formulated solely in ...

Recycling nutrients is essential for closing nutrient loops within a circular economy. Using locally available resources such as human excreta to produce bio-based recycling fertilizers can substitute mineral fertilizers and thereby promote ...

Warming-induced radial growth reduction in Betula albosinensis, eastern Qilian Mountains, China
To improve our understanding of how climate change is impacting forest ecosystems in the semi-arid regions of northwestern China, we developed a ring-width chronology for Betula albosinensis growing in the eastern Qilian mountains.

An Information Criterion for Inferring Coupling of Distributed Dynamical Systems
The behaviour of many real-world phenomena can be modelled by nonlinear dynamical systems whereby a latent system state is observed through a filter. We are interested in interacting subsystems of this form, which we model by a set of coupled maps as a ...

Scenario development, qualitative causal analysis and system dynamics
The aim of this article is to demonstrate that technology assessments can be supported by methods such as scenario modeling and qualitative causal analysis. At Siemens, these techniques are used to develop preliminary purely qualitative models.
