From Galilei to Euclidean Carroll and the Alice Particle: The Times They Are a-Changin'
Eric A. Bergshoeff, Luca Romano, Jan Rosseel +3
In generalized, also known as -brane Galilei limits, the speed of light becomes infinite in the directions transverse to a -dimensional Lorentzian worldvolume. In thi…

Heterotic String Sigma Models: Discrete Light Cone Quantization and Its Current-Current Deformation
Eric A. Bergshoeff, Kevin T. Grosvenor, Luca Romano +1
We propose a two-dimensional superstring sigma model that defines a self-contained corner of heterotic string theory, whose second quantization is heterotic matrix string theory. T…

From Relativistic Gravity to the Poisson Equation
Eric A. Bergshoeff, Giacomo Giorgi, Luca Romano
We consider the non-relativistic limit of general relativity coupled to a -form gauge field and a scalar field in arbitrary dimensions and investigate under which conditions…
