Winding Number Statistics of a Parametric Chiral Symplectic Random Matrix Ensemble
Pascal Toschka, Luke Haas, Thomas Guhr +2
The winding number is a simple topological invariant. In the case of chiral symmetry it characterises gapped phases of Fermions. We study statistical properties of this topological…
Winding Number Statistics for Chiral Random Matrices: Universal Correlations and Statistical Moments in the Unitary Case
Nico Hahn, Mario Kieburg, Omri Gat +1
The winding number is the topological invariant that classifies chiral symmetric Hamiltonians with one-dimensional parametric dependence. In this work we complete our study of the…
Bandwidth-induced saturation in multimode fiber-based absorbers
Kfir Sulimany, Dotan Halevi, Omri Gat +1
Multimode fiber-based saturable absorbers enable mode-locking in lasers, generating ultrafast pulses and providing an exceptional platform for investigating nonlinear phenomena. Pr…
Universality and Hysteresis in Slow Sweeping of Bifurcations
Roie Ezraty, Ido Levin, Omri Gat
Bifurcations in dynamical systems are often studied experimentally and numerically using a slow parameter sweep. Focusing on the cases of period-doubling and pitchfork bifurcations…
Winding Number Statistics for Chiral Random Matrices: Averaging Ratios of Parametric Determinants in the Orthogonal Case
Nico Hahn, Mario Kieburg, Omri Gat +1
We extend our recent study of winding number density statistics in Gaussian random matrix ensembles of the chiral unitary (AIII) and chiral symplectic (CII) classes. Here, we consi…
Chaotic internal dynamics of dissipative optical soliton molecules
Youjian Song, Defeng Zou, Omri Gat +2
When a laser cavity supports the propagation of several ultrashort pulses, these pulses interact and can form compact bound states called soliton molecules. Soliton molecules are f…
