We propose a holographic correspondence between the action integral I describing the mechanics of a finite number of degrees of freedom in the bulk, and the entropy S of the boundary (a holographic screen) enclosing that ...
[EN] It is shown that the theory of causal fermion systems gives rise to a novel mechanism for dark matter and dark energy. This mechanism is first worked out for cubical subsets of Minkowski space with periodic boundary ...

[EN] A classification methodology based on an experimental study is proposed towards a fast pre-diagnosis of attention deficit. Our sample consisted of school-aged children between 8 and 12 years from Valencia, Spain. The ...

[EN] In this paper, the Samara-Valencia model for heat transfer in grinding is considered. This model is particularized to the case of wet grinding, assuming a constant heat transfer coefficient on the workpiece surface ...

Quantum mechanics emerges à la Verlinde from a foliation of 3 by holographic screens, when regarding the latter as entropy reservoirs that a particle can exchange entropy with. This entropy is quantized in units of Boltzmann's ...

[EN] A dynamical estimate is given for the Boltzmann entropy of the Universe, under the simplifying assumptions provided by Newtonian cosmology. We first model the cosmological fluid as the probability fluid of a ...

[EN] The holographic principle sets an upper bound on the total (Boltzmann) entropy content
of the Universe at around 10123kB (kB being Boltzmann¿s constant). In this work we point out
the existence of a remarkable duality ...

The emergent nature of quantum mechanics is shown to follow from a precise correspondence with the classical theory of irreversible thermodynamics. Specifically, the linear (or Gaussian) regime of the latter can be put in ...
Acosta Iglesias, Dagoberto; Fernández de Córdoba Castellá, Pedro José; Isidro San Juan, José María; González-Santander Martínez, Juan Luis(World Scientific Publishing, 2013-04)
We present an explicit correspondence between quantum mechanics and the classical theory of irreversible thermodynamics as developed by Onsager, Prigogine et al. Our correspondence maps irreversible Gaussian Markov processes ...

It has been argued that gravity acts dissipatively on quantum-mechanical systems, inducing thermal fluctuations that become indistinguishable from quantum fluctuations. This has led some authors to demand that some form ...

[EN] The classical thermostatics of equilibrium processes is shown to possess a quantum mechanical dual theory with a finite dimensional Hilbert space of quantum states. Specifically, the kernel of a certain Hamiltonian ...

We present a closed analytical solution for the time evolution of the temperature field in dry grinding for any time-dependent friction profile between the grinding wheel and the workpiece. We base our solution in the ...

We present a brief overview of some key concepts in the theory of generalized complex manifolds. This new geometry interpolates, so to speak, between symplectic geometry and complex geometry. As such it provides an ideal ...

[EN] In this paper, the cosmological constant and the Boltzmann entropy of a Newtonian Universe filled with a perfect fluid are computed, under the assumption that spatial sections are copies of 3-dimensional hyperbolic space.

[ES] Se deriva un mapeo entre la ecuación de Schrödinger y la de Navier-Stokes, que generaliza el que propuso Madelung en 1926 con la ecuación de Euler. Dado que la mecánica de fluidos es el paradigma de teoría emergente, ...
