In this paper, the foundations of classical phenomenological thermodynamics are being thoroughly revisited. A new rigorous basis for thermodynamics is laid out in the main text and presented in...

Random Feature (RF) models are used as efficient parametric approximations of kernel methods. We investigate, by means of random matrix theory, the connection between Gaussian RF models and...

We consider a scheme for on-demand teleportation of a dual-rail electron qubit state, based on single-electron sources and detectors. The scheme has a maximal efficiency of 25%, which is limited...

We consider level-sets of the Gaussian free field on \mathbb Z^d, for d\geq 3, above a given real-valued height parameter h. As h varies, this defines a canonical percolation model with strong,...

Classical Hamiltonian systems with conserved charges and those with constraints often describe dynamics on a pre-symplectic manifold. Here we show that a pre-symplectic manifold is also the...

Quot schemes of quotients of a trivial bundle of arbitrary rank on a nonsingular projective surface X carry perfect obstruction theories and virtual fundamental classes whenever the quotient...

We show that when one draws a simple conformal loop ensemble (CLE_kappa for\kappa \in (8/3,4)) on an independent \sqrt{\kappa}-Liouville quantum gravity (LQG) surface and explores the CLE in a...

Beyond future applications, quantum networks open interesting fundamental perspectives, notably novel forms of quantum correlations. In this work we discuss quantum correlations in networks from...

We investigate for the first time weak lensing in a high-resolution relativistic N-body simulation, which includes all relevant effects from general relativity. We integrate the photon geodesics...

We consider N bosons in a box with volume one, interacting through a two-body potential with scattering length of the order N^{-1+\kappa}, for \kappa>0. Assuming that \kappa\in (0;1/43), we...

The ground states of the spin-S antiferromagnetic chain H_\textrm{AF} with a projection-based interaction and the spin-1/2 XXZ-chain H_\textrm{XXZ} at anisotropy parameter \Delta=\cosh(\lambda)...

Physics is formulated in terms of timeless classical mathematics. A formulation on the basis of intuitionist mathematics, built on time-evolving processes, would offer a perspective that is...
