Compact space catalysis of false vacuum decay and Schwinger effect
Saquib Hassan, John March-Russell
We study zero-temperature false vacuum decay in compact spatial dimensions and show that for volumes below a critical value a new bounce solution, different from Coleman's cele…
Chern-Simons Induced Thermal Friction on Axion Domain Walls
Saquib Hassan, Gaurang Ramakant Kane, John March-Russell +1
We study the dynamics and interactions of the solitonic domain walls that occur in realistic axion electrodynamics models including the Chern-Simons interaction, $aε_{μνλσ}F^{μν} F…
De Sitter space constraints on brane tensions and couplings
Saquib Hassan, Georges Obied, John March-Russell
We argue for the existence of bounds on the tensions of -branes in de Sitter space in terms of the Hubble rate and the strength of a class of Chern-Simons-like couplings. The wo…
Chern-Simons bubbles: Lopsided false vacuum decay in axion electrodynamics
Saquib Hassan, John March-Russell, Georges Obied
We study axion electrodynamics, including the Chern-Simons interaction term, in the presence of parallel background electric and magnetic fields, as can for example occur in certai…
