The most powerful astrophysical events: Gravitational-wave peak luminosity of binary black holes as predicted by numerical relativity
David Keitel, Xisco Jiménez Forteza, Sascha Husa +9
For a brief moment, a binary black hole (BBH) merger can be the most powerful astrophysical event in the visible universe. Here we present a model fit for this gravitational-wave p…
A simple unified view of branching process statistics: random walks in balanced logarithmic potentials
Serena di Santo, Pablo Villegas, Rafaella Burioni +1
We revisit the problem of deriving the mean-field values of avalanche critical exponents in systems with absorbing states. These are well-known to coincide with those of an un-bias…
Probing Extreme-Density Matter with Gravitational Wave Observations of Binary Neutron Star Merger Remnants
David Radice, Sebastiano Bernuzzi, Walter Del Pozzo +2
We present a proof-of-concept study, based on numerical-relativity simulations, of how gravitational waves (GWs) from neutron star merger remnants can probe the nature of matter at…
Generation of robust entangled states in a non-hermitian periodically driven two-band Bose-Hubbard system
Carlos A. Parra-Murillo, Manuel H. Muñoz-Arias, Javier Madroñero +1
A many-body Wannier-Stark system coupled to an effective reservoir is studied within a non-Hermitian approach in the presence of a periodic driving. We show how the interplay of di…
Effective-one-body waveforms for binary neutron stars using surrogate models
Benjamin D. Lackey, Sebastiano Bernuzzi, Chad R. Galley +2
Gravitational-wave observations of binary neutron star systems can provide information about the masses, spins, and structure of neutron stars. However, this requires accurate and…
Chaos and correlated avalanches in excitatory neural networks with synaptic plasticity
Fabrizio Pittorino, Miguel Ibáñez-Berganza, Matteo di Volo +2
A collective chaotic phase with power law scaling of activity events is observed in a disordered mean field network of purely excitatory leaky integrate-and-fire neurons with short…
Burstiness and tie reinforcement in time varying social networks
Enrico Ubaldi, Alessandro Vezzani, Marton Karsai +2
We introduce a time-varying network model accounting for burstiness and tie reinforcement observed in social networks. The analytical solution indicates a non-trivial phase diagram…
Self-Organized Bistability Associated With First-Order Phase Transitions
Serena di Santo, Raffaella Burioni, Alessandro Vezzani +1
Self-organized criticality elucidates the conditions under which physical and biological systems tune themselves to the edge of a second-order phase transition, with scale invarian…
Applications of fidelity measures to complex quantum systems
Sandro Wimberger
We revisit the fidelity as a measure for the stability and the complexity of the quantum motion of single and many-body systems. Within the context of cold atoms, we present on ove…
Spectral analysis of two-dimensional Bose-Hubbard models
David Fischer, Darius Hoffmann, Sandro Wimberger
One-dimensional Bose-Hubbard models are well known to obey a transition from regular to quantum-chaotic spectral statistics. We are extending this concept to relatively simple two-…
Framing and localization in Chern-Simons theories with matter
Marco S. Bianchi, Luca Griguolo, Matias Leoni +3
Supersymmetric localization provides exact results that should match QFT computations in some regularization scheme. The agreement is particularly subtle in three dimensions where…
Surprises from the resummation of ladders in the ABJ(M) cusp anomalous dimension
Marisa Bonini, Luca Griguolo, Michelangelo Preti +1
We study the cusp anomalous dimension in N=6 ABJ(M) theory, identifying a scaling limit in which the ladder diagrams dominate. The resummation is encoded into a Bethe-Salpeter equa…
A quantum random walk of a Bose-Einstein condensate in momentum space
Gil Summy, Sandro Wimberger
Each step in a quantum random walk is typically understood to have two basic components; a `coin-toss' which produces a random superposition of two states, and a displacement which…
Fourier-space entanglement of spin chains
Miguel Ibáñez-Berganza, Javier Rodríguez-Laguna, Germán Sierra
Entanglement between different regions in momentum space is studied for ground states of some spin-chain Hamiltonians: the XY model, the Ising model in a transverse field (ITF) and…
