Topological interactions of Nambu-Goldstone bosons in quantum many-body systems
Tomas Brauner, Sergej Moroz
We classify effective actions for Nambu-Goldstone (NG) bosons assuming absence of anomalies. Special attention is paid to Lagrangians invariant only up to a surface term, shown to…
Symmetries and currents of the ideal and unitary Fermi gases
Xavier Bekaert, Elisa Meunier, Sergej Moroz
The maximal algebra of symmetries of the free single-particle Schroedinger equation is determined and its relevance for the holographic duality in non-relativistic Fermi systems is…
Towards a gravity dual of the unitary Fermi gas
Xavier Bekaert, Elisa Meunier, Sergej Moroz
Inspired by the method of null dimensional reduction and by the holographic correspondence between Vasiliev's higher-spin gravity and the critical O(N) model, a bulk dual of the un…
Nonrelativistic scale anomaly, and composite operators with complex scaling dimensions
Sergej Moroz
It is demonstrated that a nonrelativistic quantum scale anomaly manifests itself in the appearance of composite operators with complex scaling dimensions. In particular, we study n…
Below the Breitenlohner-Freedman bound in the nonrelativistic AdS/CFT correspondence
Sergej Moroz
We propose that there is no analogue of the Breitenlohner-Freedman stability bound on the mass of a scalar field in the context of the nonrelativistic AdS/CFT correspondence. Our t…
Nonrelativistic inverse square potential, scale anomaly, and complex extension
Sergej Moroz, Richard Schmidt
The old problem of a singular, inverse square potential in nonrelativistic quantum mechanics is treated employing a field-theoretic, functional renormalization method. An emergent…
