Oleg Viro introduced an invariant of rigid isotopy for real algebraic knots and links in RP3 which can be viewed as a first order Vassiliev invariant. In this paper we classify real...

Scrambling in interacting quantum systems out of equilibrium is particularly effective in the chaotic regime. Under time evolution, initially localized information is said to be scrambled as it...

The work is motivated by the puzzling results of the recent experiment [S. Tewari et al., Phys. Rev. B 93, 035420 (2016)], where a robust coherence recovery from a certain energy was detected...

We introduce a notion of weakly log-canonical Poisson structures on positive varieties with potentials. Such a Poisson structure is log-canonical up to terms dominated by the potential. To a...

We propose a class of {\rm AdS}_3/{\rm CFT}_2 dualities with N=(2,2) supersymmetry. These dualities relate string theory on {\rm AdS}_3 \times ({\rm S}^3\times \mathbb{T}^4)/{\rm G} to marginal...

We prove that the K-theoretic Nekrasov instanton partition functions have a finite radius of convergence in the instanton counting parameter and are holomorphic functions of the Coulomb...

We consider the interacting, spin conserving, extended Kane-Mele-Hubbard model, and we rigorously establish the exact quantization of the edge spin conductance and the validity of the Helical...

The quantum theory of indirect measurements in physical systems is studied. The example of an indirect measurement of an observable represented by a self-adjoint operator N with finite spectrum...

We derive the relativistic Vlasov equation from quantum Hartree dynamics for fermions with relativistic dispersion in the mean-field scaling, which is naturally linked with an effective...

For expansions in one-dimensional conformal blocks, we provide a rigorous link between the asymptotics of the spectral density of exchanged primaries and the leading singularity in the crossed...

The TS/ST correspondence relates the spectral theory of certain quantum mechanical operators, to topological strings on toric Calabi-Yau threefolds. So far the correspondence has been formulated...

We study the edge transport properties of 2d interacting Hall systems, displaying single-mode chiral edge currents. For this class of many-body lattice models, including for instance the...
