Learning About Objects by Learning to Interact with Them
Martin Lohmann, Jordi Salvador, Aniruddha Kembhavi +1
Much of the remarkable progress in computer vision has been focused around fully supervised learning mechanisms relying on highly curated datasets for a variety of tasks. In contra…
Three-dimensional tricritical spins and polymers
Roland Bauerschmidt, Martin Lohmann, Gordon Slade
We consider two intimately related statistical mechanical problems on : (i) the tricritical behaviour of a model of classical unbounded -component continuous spins…
Critical exponent for the magnetization of the weakly coupled model
Martin Lohmann
We consider the weakly coupled theory on , in a weak magnetic field , and at the chemical potential for which the theory is critical if . We pro…
The density of states of 1D random band matrices via a supersymmetric transfer operator
Margherita Disertori, Martin Lohmann, Sasha Sodin
Recently, T. and M. Shcherbina proved a pointwise semicircle law for the density of states of one-dimensional Gaussian band matrices of large bandwidth. The main step of their proo…
Critical two-point function for long-range models below the upper critical dimension
Martin Lohmann, Gordon Slade, Benjamin C. Wallace
We consider the -component lattice spin model () and the weakly self-avoiding walk () on , in dimensions . We study long-range model…
Some improved nonperturbative bounds for Fermionic expansions
Martin Lohmann
We reconsider the Gram-Hadamard bound as it is used in constructive quantum field theory and many body physics to prove convergence of Fermionic perturbative expansions. Our approa…
Single Scale Cluster Expansions with Applications to Many Boson and Unbounded Spin Systems
Martin Lohmann
We develop a cluster expansion to show exponential decay of correlations for quite general single scale spin systems, as they arise in lattice quantum field theory and discretized…
