Y. Y. Atas 1 E. Bogomolny 1 Philosophical transactions of the Royal Society of London. Series A: Mathematical and physical sciences, Royal Society, The, 2014, 372, pp.20120520 It was demonstrated in [Phys. Rev. E 86, 021104, (2012)], that the ground-state wave functions for a large variety of one-dimensional spin-1/2 models are multifractals in the natural […]

Jan Mölter 1 Thomas Barthel 2, 1 Ulrich Schollwöck 1 Vincenzo Alba 1 Journal of Statistical Mechanics, 2014, pp.P10029 We investigate entanglement properties of the excited states of the spin-1/2 Heisenberg (XXX) chain with isotropic antiferromagnetic interactions, by exploiting the Bethe ansatz solution of the model. We consider eigenstates obtained from both real and complex

Sergey Matveenko 1, 2 Stephane Ouvry 2 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2014, 47, pp.185001 When random walks on a square lattice are biased horizontally to move solely to the right, the probability distribution of their algebraic area can be exactly obtained. We explicitly map this biased

Thierry Jolicoeur 1 Takahiro Mizusaki 2 Philippe Lecheminant 3 Physical Review B (Condensed Matter), American Physical Society, 2014, 90, pp.075116 We study the Gaffnian trial wavefunction proposed to describe fractional quantum Hall correlations at Bose filling factor $\nu=2/3$ and Fermi filling $\nu=2/5$. A family of Hamiltonians interpolating between a hard-core interaction for which the physics

Daniel Braun 1 Olivier Giraud 2 Ion Nechita 1 Clement Pellegrini 3 Marko Znidaric 4 Journal of Physics A: Mathematical and Theoretical, Institute of Physics: Hybrid Open Access, 2014, 47 (13), pp.135302. <10.1088/1751-8113/47/13/135302> We investigate the set of quantum channels acting on a single qubit. We provide a compact generalization of the Fujiwara-Algoet conditions for

Gernot Akemann 1 Dario Villamaina 2 Pierpaolo Vivo 3 Physical Review E, American Physical Society, 2014, 89, pp.062146 We consider an invariant random matrix model where the standard Gaussian potential is distorted by an additional single pole of order $m$. We compute the average or macroscopic spectral density in the limit of large matrix size,

Jean-Michel Caillol 1 Martin Trulsson 2 The Journal of Chemical Physics, 2014, 141, pp.124111 We present a new method for Monte Carlo or Molecular Dynamics numerical simulations of three dimensional polar fluids. The simulation cell is defined to be the surface of the northern hemisphere of a four-dimensional (hyper)sphere. The point dipoles are constrained to
