Nuclear Physics B, Elsevier, 2019. ⟨hal-02365447⟩ Being inspired by the connection between 2D Yang-Mills (YM) theory and (1+1)D « vicious walks » (VW), we consider different incarnations of large-$N$ Douglas-Kazakov (DK) phase transition […]

Physical Review A, American Physical Society 2019, 100 (4), ⟨10.1103/PhysRevA.100.042707⟩. ⟨hal-02395504⟩ We calculate the effective three-body force for bosons interacting with each other by a two-body potential tuned to a narrow zero crossing in any

Enej IlievskiEoin Quinn 1 Enej Ilievski, Eoin Quinn. The equilibrium landscape of the Heisenberg spin chain. SciPost Physics, SciPost Foundation, 2019, 7 (3), ⟨10.21468/SciPostPhys.7.3.033⟩. ⟨hal-02295879⟩ We characterise the equilibrium landscape, the entire manifold of local equilibrium states, of an interacting integrable quantum model. Focusing on the isotropic Heisenberg spin chain, we describe in full generality

Stephane Ouvry 1 Shuang Wu 1 Stephane Ouvry, Shuang Wu. The algebraic area of closed lattice random walks. Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2019, ⟨10.04098⟩. ⟨hal-02292208⟩ We propose a formula for the enumeration of closed lattice random walks of length $n$ enclosing a given algebraic area. The information is contained in

Pierre Ronceray 1 Chase Broedersz 2 Martin Lenz 3 Soft Matter, Royal Society of Chemistry, 2019 The production of mechanical stresses in living organisms largely relies on localized, force-generating active units embedded in filamentous matrices. Numerical simulations of discrete fiber networks with fixed boundaries have shown that buckling in the matrix dramatically amplifies the resulting
