Transient Performance of Electric Power Networks under Colored Noise
T. Coletta, B. Bamieh, Ph. Jacquod
New classes of performance measures have been recently introduced to quantify the transient response to external disturbances of coupled dynamical systems on complex networks. Thes…
Performance Measures in Electric Power Networks under Line Contingencies
Tommaso Coletta, Philippe Jacquod
Classes of performance measures expressed in terms of -norms have been recently introduced to quantify the response of coupled dynamical systems to external perturbatio…
Robustness of Synchrony in Complex Networks and Generalized Kirchhoff Indices
Melvyn Tyloo, Tommaso Coletta, Philippe Jacquod
In network theory, a question of prime importance is how to assess network vulnerability in a fast and reliable manner. With this issue in mind, we investigate the response to para…
Resistance distance criterion for optimal slack bus selection
Tommaso Coletta, Philippe Jacquod
We investigate the dependence of transmission losses on the choice of a slack bus in high voltage AC transmission networks. We formulate a transmission loss minimization problem in…
Finite Size Scaling in the Kuramoto Model
Tommaso Coletta, Robin Delabays, Philippe Jacquod
We investigate the scaling properties of the order parameter and the largest nonvanishing Lyapunov exponent for the fully locked state in the Kuramoto model with a finite number $N…
Multistability of Phase-Locking in Equal-Frequency Kuramoto Models on Planar Graphs
Robin Delabays, Tommaso Coletta, Philippe Jacquod
The number of stable fixed points of locally coupled Kuramoto models depends on the topology of the network on which the model is defined. It has been shown that cycl…
Semiclassical theory of the magnetization process of the triangular lattice Heisenberg model
Tommaso Coletta, Tamás Tóth, Karlo Penc +1
Motivated by the numerous examples of 1/3 magnetization plateaux in the triangular lattice Heisenberg an- tiferromagnet with spins ranging from 1/2 to 5/2, we revisit the semiclass…
Multistability of Phase-Locking and Topological Winding Numbers in Locally Coupled Kuramoto Models on Single-Loop Networks
Robin Delabays, Tommaso Coletta, Philippe Jacquod
Determining the number of stable phase-locked solutions for locally coupled Kuramoto models is a long-standing mathematical problem with important implications in biology, condense…
Dynamical structure factors and excitation modes of the bilayer Heisenberg model
M. Lohöfer, T. Coletta, D. G. Joshi +4
Using quantum Monte Carlo simulations along with higher-order spin-wave theory, bond-operator and strong-coupling expansions, we analyse the dynamical spin structure factor of the…
Linear Stability and the Braess Paradox in Coupled Oscillators Networks and Electric Power Grids
Tommaso Coletta, Philippe Jacquod
We investigate the influence that adding a new coupling has on the linear stability of the synchronous state in coupled oscillators networks. Using a simple model we show that, dep…
Semiclassical evidence of columnar order in the fully frustrated transverse field Ising model on the square lattice
Tommaso Coletta, Sergey E. Korshunov, Frédéric Mila
We investigate the zero-temperature phase diagram of the fully frustrated transverse field Ising model on the square lattice both in the classical limit and in the presence of quan…
Quantum stabilization of classically unstable plateau structures
T. Coletta, M. E. Zhitomirsky, F. Mila
Motivated by the intriguing report, in some frustrated quantum antiferromagnets, of magnetization plateaus whose simple collinear structure is {\it not} stabilized by an external m…

Sandro Wenzel, Tommaso Coletta, Sergey E. Korshunov +1
Using extensive classical and quantum Monte Carlo simulations, we investigate the ground-state phase diagram of the fully frustrated transverse field Ising model on the square latt…
Semiclassical approach to ground-state properties of hard-core bosons in two dimensions
Tommaso Coletta, Nicolas Laflorencie, Frédéric Mila
Motivated by some inconsistencies in the way quantum fluctuations are included beyond the classical treatment of hard-core bosons on a lattice in the recent literature, we revisit…
