Relativistic Fractons and their Dust
Qiuyue Liang, Tom Melia
We define a relativistic version of the global symmetries responsible for the restricted mobility of fracton quasiparticles. The theories have a symmetry current that is proportion…
On the EFT of Conformal Symmetry Breaking
Kurt Hinterbichler, Qiuyue Liang, Mark Trodden
Conformal symmetry can be spontaneously broken due to the presence of a defect or other background, which gives a symmetry-breaking vacuum expectation value (VEV) to some scalar op…
Double Copy for Massive Scalar Field Theories
Mariana Carrillo González, Qiuyue Liang, Mark Trodden
We explore extensions of the double copy to massive theories and find a new cubic theory with a local double copy. We consider the nonlinear sigma model and the special galileon th…
An Effective Field Theory for Binary Cosmic Strings
Mariana Carrillo Gonzalez, Qiuyue Liang, Mark Trodden
We extend the effective field theory (EFT) formalism for gravitational radiation from a binary system of compact objects to the case of extended objects. In particular, we study th…
Fluctuations through a Vibrating Bounce
Robert Brandenberger, Qiuyue Liang, Rudnei O. Ramos +1
We study the evolution of cosmological perturbations in a non-singular bouncing cosmology with a bounce phase which has superimposed oscillations of the scale factor. We identify l…
Running of the Spectrum of Cosmological Perturbations in String Gas Cosmology
Robert Brandenberger, Guilherme Franzmann, Qiuyue Liang
We compute the running of the spectrum of cosmological perturbations in String Gas Cosmology, making use of a smooth parametrization of the transition between the early Hagedorn ph…
