# Field theory for zero temperature soft anharmonic spin glasses in a field

@article{Urbani2022FieldTF, title={Field theory for zero temperature soft anharmonic spin glasses in a field}, author={Pierfrancesco Urbani}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2022}, volume={55} }

We introduce a finite dimensional anharmonic soft spin glass in a field and show how it allows the construction a field theory at zero temperature and the corresponding loop expansion. The mean field level of the model coincides with a recently introduced fully connected model, the KHGPS model, and it has a spin glass transition in a field at zero temperature driven by the appearance of pseudogapped non-linear excitations. We analyze the zero temperature limit of the theory and the behavior of…
