Could thermal fluctuations seed cosmic structure?
Joao Magueijo, Levon Pogosian
We examine the possibility that thermal, rather than quantum, fluctuations are responsible for seeding the structure of our universe. We find that while the thermalization conditio…
Domain Wall Lattices
Levon Pogosian, Tanmay Vachaspati
We construct lattices with alternating kinks and anti-kinks. The lattice is shown to be stable in certain models. We consider the forces between kinks and antikinks and find that t…
Signatures of primordial helicity in the CMBR
Levon Pogosian, Tanmay Vachaspati, Serge Winitzki
We have studied ways in which helical primordial magnetic fields could be constrained by measurements of the cosmic microwave background radiation (CMBR). If there were helical flo…
Triplication of SU(5) monopoles
Levon Pogosian, Daniele A. Steer, Tanmay Vachaspati
We investigate all spherically symmetric fundamental monopole solutions with fixed topological charge in the SU(5) --> SU(3)xSU(2)xU(1)/Z_3xZ_2 symmetry breaking. We find that ther…
