Stability of Closed Timelike Curves in a Galileon Model
Jarah Evslin
Recently Burrage, de Rham, Heisenberg and Tolley have constructed eternal, classical solutions with closed timelike curves (CTCs) in a Galileon model coupled to an auxiliary scalar…
Neutrino Splitting and Density-Dependent Dispersion Relations
Emilio Ciuffoli, Jarah Evslin, Xiaojun Bi +1
We show that particles can split only when their group velocity exceeds their phase velocity. In this sense the splitting process is the quantum analog of the modulational instabil…
High Q BPS Monopole Bags are Urchins
Jarah Evslin, Sven Bjarke Gudnason
It has been known for 30 years that 't Hooft-Polyakov monopoles of charge Q greater than one cannot be spherically symmetric. 5 years ago, Bolognesi conjectured that, at some point…
Challenges Confronting Superluminal Neutrino Models
Jarah Evslin
This talk opens the CosPA2011 session on OPERA's superluminal neutrino claim. I summarize relevant observations and constraints from OPERA, MINOS, ICARUS, KamLAND, IceCube and LEP…
Neutrino Dispersion Relations from a Dark Energy Model
Emilio Ciuffoli, Jarah Evslin, Jie Liu +1
We consider a model in which the neutrino is kinetically coupled to a scalar field and study its implications for environmentally dependent neutrino velocities. Following the usual…
Bouncing Galileon Cosmologies
Taotao Qiu, Jarah Evslin, Yi-Fu Cai +2
We present nonsingular, homogeneous and isotropic bouncing solutions of the conformal Galileon model. We show that such solutions necessarily begin with a radiation-dominated contr…
