Unified Description of Nambu-Goldstone Bosons without Lorentz Invariance

Author(s): Haruki Watanabe and Hitoshi Murayama Using the effective Lagrangian approach, we clarify general issues about Nambu-Goldstone bosons without Lorentz invariance. We show how to count their...

Interacting topological phases and modular invariance

Author(s): Shinsei Ryu and Shou-Cheng Zhang We discuss (2+1)-dimensional topological superconductors with Nf left- and right-moving Majorana edge modes and a Z2×Z2 symmetry. In the absence of...

Momentum routing invariance in Feynman diagrams and quantum symmetry breakings

Author(s): L. C. Ferreira, A. L. Cherchiglia, Brigitte Hiller, Marcos Sampaio, and M. C. Nemes We illustrate with examples that quantum symmetry breakings in perturbation theory are connected to...

Chiral quark-soliton model with broken scale invariance for nuclear matter

Author(s): Alessandro Drago and Valentina Mantovani Sarti We present a model for describing nuclear matter at finite density based on quarks interacting with chiral fields σ and π and with vector...

Testing violations of Lorentz invariance with cosmic rays

Author(s): R. Cowsik, T. Madziwa-Nussinov, S. Nussinov, and U. Sarkar Cosmic rays are the highest energy particles available for our study, and as such serve as excellent probes of the effects of...

Apparent Low-Energy Scale Invariance in Two-Dimensional Fermi Gases

Author(s): Edward Taylor and Mohit Randeria Recent experiments on a 2D Fermi gas find an undamped breathing mode at twice the trap frequency over a wide range of parameters. To understand this...

Deformed bubbles and Lorentz invariance in vacuum decay

Author(s): Michael Dine, Patrick Draper, and Chang-Soon Park Recently, questions have been raised about the role of Lorentz invariance in false vacuum decay. It has been argued that infinities may...
