Cosmological angular momentum from quantum rotation
Bo-Qiang Lu
The origin of cosmic angular momentum is a fundamental question in structure formation. We propose a novel mechanism that generates spatial angular momentum directly from quantum f…
Domain Wall as Cosmological Oscillator
Bo-Qiang Lu
In this study, we examine the domain wall within the framework of a cosmological harmonic oscillator. We investigate the interaction between the domain wall and a periodic backgrou…
The topological spectrum of high dimensional quantum states
Robert de Mello Koch, Pedro Ornelas, Neelan Gounden +3
Topology has emerged as a fundamental property of many systems, manifesting in cosmology, condensed matter, high-energy physics and waves. Despite the rich textures, the topology h…
Scalar-induced gravitational wave from domain wall perturbation
Bo-Qiang Lu
Domain walls represent two-dimensional topological defects that emerge from the spontaneous breaking of discrete symmetries in various new physics models. In this study, we underta…
