In quantum mechanics, a given initial state of a closed interacting quantum system will evolve unitarily according to its HamiltonianH. A fundamental assumption in statistical physics is that a generic closed quantum many-body system thermalizes under its own dynamics1,2. This implies that, under ...
This raises questions as to whether the models contain enough of the fundamental physics to be able to predict certain colloid thermal behaviours or whether the models might have been a result of a forced curve fitting correlation. Fig. 9 Accuracy of the tested thermal conductivity models for ...
This raises questions about where the source of mantle plumes is, and what plumes look like deep in the mantle. The dynamics of plume formation place constraints on possible source locations. Thermal plumes in the earth's mantle can be attributed to instabilities in hot thermal boundary layers....
Can we dissect the agent’s NN – a computational object that is typically treated as a “black box” – to gain insight into its function38,39,40? And, how does a learned policy compare with the thermal soaring behavior of birds in the wild? Here, we address these questions by ...

In the last chapter, he addresses some general questions involving irreversible processes and fluctuations. A large amount of material is presented to facilitate students later access to more advanced works, to allow those with higher levels of curiosity to read beyond the minimum given on a topic...

12. Here we present a dayside thermal emission spectrum of the ultra-hot Jupiter WASP-18b obtained with the NIRISS13instrument on the JWST. The data span 0.85 to 2.85 μm in wavelength at an average resolving power of 400 and exhibit minimal systematics. The spectrum shows three water ...

We study two two-level atomic quantum systems (qubits) placed close to a body held at a temperature different from that of the surrounding walls. While at thermal equilibrium the two-qubit dynamics is characterized by non-entangled steady thermal states, we show that the absence of thermal equi...
