Aspects of non-relativistic quantum field theories

S Baiguera - The European Physical Journal C, 2024 - Springer
Non-relativistic quantum field theory is a framework that describes systems where the
velocities are much smaller than the speed of light. A large class of those obey Schrödinger …

EA Bergshoeff, J Gomis, J Rosseel… - Journal of Physics A …, 2019 - iopscience.iop.org
Nonrelativistic string theory is described by a sigma model with a relativistic worldsheet and
a nonrelativistic target spacetime geometry, that is called string Newton–Cartan geometry. In …

The panorama of spin matrix theory

S Baiguera, T Harmark, Y Lei - Journal of High Energy Physics, 2023 - Springer
A bstract Spin Matrix theory describes near-BPS limits of\(\mathcal {N}\)= 4 SYM theory,
which enables us to probe finite N effects like D-branes and black hole physics. In previous …

Spin Matrix Theory in near -BPS corners of = 4 super-Yang-Mills

S Baiguera, T Harmark, Y Lei - Journal of High Energy Physics, 2022 - Springer
A bstract We consider limits of\(\mathcal {N}\)= 4 super-Yang-Mills (SYM) theory that
approach BPS bounds. These limits result in non-relativistic theories that describe the …

Supersymmetric Galilean Electrodynamics

A bstract In 2+ 1 dimensions, we propose a renormalizable non-linear sigma model action
which describes the\(\mathcal {N}\)= 2 supersymmetric generalization of Galilean …

Renormalization of Galilean electrodynamics

S Chapman, L Di Pietro, KT Grosvenor… - Journal of High Energy …, 2020 - Springer
A bstract We study the quantum properties of a Galilean-invariant abelian gauge theory
coupled to a Schrödinger scalar in 2+ 1 dimensions. At the classical level, the theory with …

Universal form of the Nicolai map

O Lechtenfeld, M Rupprecht - Physical Review D, 2021 - APS
The nonlocal bosonic theory obtained from integrating out all anticommuting and auxiliary
variables in a globally supersymmetric theory is characterized by the Nicolai map. The latter …

Symmetry structure of the interactions in near-BPS corners of = 4 super-Yang-Mills

A bstract We consider limits of\(\mathcal {N}\)= 4 super-Yang-Mills (SYM) theory that
approach BPS bounds. These limits result in non-relativistic near-BPS theories that describe …

Renormalization of supersymmetric Lifshitz sigma models

Z Yan - Journal of High Energy Physics, 2023 - Springer
A bstract We study the renormalization of an\(\mathcal {N}\)= 1 supersymmetric Lifshitz
sigma model in three dimensions. The sigma model exhibits worldvolume anisotropy in …

Constructing Non-Relativistic AdS/CFT Holography
