Domain Wall Solutions
Tanmay Vachaspati
I describe domain walls and domain wall lattices in non-Abelian models.
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…
Bound states in bottomless potentials
Tanmay Vachaspati
We consider classical and quantum dynamics on potentials that are asymptotically unbounded from below. By explicit construction we find that quantum bound states can exist in certa…
Band structure in classical field theory
Michael Salem, Tanmay Vachaspati
Stability and instability bands in classical mechanics are well-studied in connection with systems such as described by the Mathieu equation. We examine whether such band structure…
