Physical Review E, 2016 When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that a more general and relevant question is "when does a system thermalize relative to a particular reference?" By relative thermalization we mean that, as well as being in a ...

Dynamic Aether as a Trigger for Spontaneous Spinorization in Early Universe
Universe, 2023 In the framework of the Einstein–Dirac-aether theory we consider a phenomenological model of the spontaneous growth of the fermion number, which is triggered by the dynamic aether.

Relativity without relativity [PDF]
Classical and Quantum Gravity, 2002 We give a derivation of general relativity and the gauge principle that is novel in presupposing neither spacetime nor the relativity principle. We consider a class of actions defined on superspace with two key properties. The first is 3-coordinate invariance. This is the only postulated symmetry, and it leads to the standard momentum constraint.

Relative torsion classes, relative tilting, and relative silting modules
Communications in Algebra, 2021 Let $\Lambda$ be an Artin algebra. In 2014, T. Adachi, O. Iyama and I. Reiten proved that the torsion funtorially finite classes in $\mathrm{mod}\,(\Lambda)$ can be described by the $\tau$-tilting theory. The aim of this paper is to introduce the notion of $F$-torsion class in $\mathrm{mod}\,(\Lambda)$, where $F$ is an additive subfunctor of $\mathrm ...

Is the Axionic Dark Matter an Equilibrium System?
Universe, 2020 We consider an axionic dark matter model with a modified periodic potential for the pseudoscalar field in the framework of the axionic extension of the Einstein-aether theory.

Advancing physiology education by understanding the multiple dimensions of homeostasis
Frontiers in Physiology, 2023 Homeostasis of the internal environment has been considered the central organizing concept of physiology. However, current definitions of it in textbooks and online teaching sources do not sufficiently reflect how homeostasis serves its central unifying ...

The Confrontation between General Relativity and Experiment [PDF]
Living Reviews in Relativity, 2005 The status of experimental tests of general relativity and of theoretical frameworks for analyzing them is reviewed. Einstein’s equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of special relativity, and ...

Relative Prices and Relative Prosperity [PDF]
American Economic Review, 2007 The positive correlation between real investment rates and real income levels across countries is driven largely by differences in the price of investment relative to output. The high relative price of investment in poor countries is due to the low price of consumption goods in those countries. Investment prices are no higher in poor countries.
