Stability of an oscillon un the SU (2) gauged Higgs model
… the spherical ansatz of the SU(2) gauged Higgs model -the standard model of the weak interactions without electromagnetism and fermions. In this thesis, we study the stability of these objects. We do this by adding a massless mode to the model and coupling it to the oscillating fields contained …

Exploring linear and nonlinear electromagnetic responses in topological materials
… and contemplate the possible collective phonon modes mediating these responses. We consider the onset of the phase-modulating (massless) collective modes and amplitude-modulating (massive) collective modes in these responses. We find that the tilted Weyl-charge-density wave model can yield …
