Machine learning, quantum chaos, and pseudorandom evolution
, 2020 By modeling quantum chaotic dynamics with ensembles of random operators, we explore howmachine learning learning algorithms can be used to detect pseudorandom behavior in qubit systems.We analyze samples consisting of pieces of correlation functions and ...

, 2009 In this manuscript we give thought to the aftermath on the stable probability density function when standard multiplicative cascades are generalised cascades based on the $q$-product of Borges that emerged in the context of non-extensive statistical ...

On non-equilibrium physics and string theory
, 2013 In this article we review the relation between string theory and non-equilibrium physics based on our previously published work. First we explain why a theory of quantum gravity and non-equilibrium statistical physics should be related in the first place.

Overlaps between eigenstates of the XXZ spin-1/2 chain and a class of simple product states
, 2014 We consider a class of quantum quenches in the spin-1/2 XXZ chain, where the initial state is of a simple product form. Specific examples are the N\'eel state, the dimer state and the q-deformed dimer state.

Collective effects enhancing power and efficiency [PDF]
, 2017 Energy conversion is most efficient for micro or nano machines with tight coupling between input and output power. To reach meaningful amounts of power, ensembles of $N$ such machines must be considered.

Critical domain walls in the Ashkin-Teller model
, 2011 We study the fractal properties of interfaces in the 2d Ashkin-Teller model. The fractal dimension of the symmetric interfaces is calculated along the critical line of the model in the interval between the Ising and the four-states Potts models.

Short distance correlators in the XXZ spin chain for arbitrary string distributions
, 2014 In this letter we consider expectation values of local correlators in highly excited states of the spin-1/2 XXZ chain. Assuming that the string hypothesis holds we formulate the following conjecture: The correlation functions can be computed using the ...

Properties of thermal quantum states: locality of temperature, decay of correlations, and more
, 2019 We review several properties of thermal states of spin Hamiltonians with short range interactions. In particular, we focus on those aspects in which the application of tools coming from quantum information theory has been specially successful in the ...

The Origins of Computational Mechanics: A Brief Intellectual History and Several Clarifications [PDF]
, 2017 The principle goal of computational mechanics is to define pattern and structure so that the organization of complex systems can be detected and quantified.
