Quasi-universality in mixed salt-free counterions systems

M. Trulsson 1 Ladislav Šamaj 2 E. Trizac 1 EPL – Europhysics Letters, European Physical Society/EDP Sciences/Società Italiana di Fisica/IOP Publishing, 2017, 118 (1), pp.16001 The screening of plate-plate interactions by counterions is an age-old problem. We revisit this classic question when counterions exhibit a distribution of charges. While it is expected that the long-distance

Quantum quenches with random matrix Hamiltonians and disordered potentials

Fabian Kolley 1 Oriol Bohigas 2 Boris V. Fine 1, 3 Annalen der Physik, 2017 We numerically investigate statistical ensembles for the occupations of eigenstates of an isolated quantum system emerging as a result of quantum quenches. The systems investigated are sparse random matrix Hamiltonians and disordered lattices. In the former case, the quench consists

Quantum Ising model in transverse and longitudinal fields: chaotic wave functions

Y. Y. Atas 1 E. Bogomolny 2 Journal of Physics A: Mathematical and General , IOP Publishing, 2017, 50, pp.385102 The construction of a statistical model for eigenfunctions of the Ising model in transverse and longitudinal fields is discussed in detail for the chaotic case. When the number of spins is large, each wave function

Probability distribution of the entanglement across a cut at an infinite-randomness fixed point

Trithep Devakul 1 Satya N. Majumdar 2 David A. Huse 1 Physical Review B : Condensed matter and materials physics, American Physical Society, 2017, 95 (10), pp.104204 We calculate the probability distribution of entanglement entropy S across a cut of a finite one dimensional spin chain of length L at an infinite randomness fixed point

Pickands’ constant at first order in an expansion around Brownian motion

Mathieu Delorme 1 Alberto Rosso 2 Kay Jörg Wiese 1 Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2017, 50, pp.16LT04 In the theory of extreme values of Gaussian processes, many results are expressed in terms of the Pickands constant $\mathcal{H}_{\alpha}$. This constant depends on the local self-similarity exponent $\alpha$ of the process, i.e.
