Electroweak First-Order Phase Transition Triggered by Non-Gaussian Fluctuations of a -Symmetric Spectator Scalar
Bo-Qiang Lu
We propose a novel mechanism to trigger a first-order cosmological electroweak phase transition using non-Gaussian primordial fluctuations of a -symmetric spectator s…
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…
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…
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…
Quantum Skyrmions in general quantum channels: topological noise rejection and the discretization of quantum information
Robert de Mello Koch, Bo-Qiang Lu, Pedro Ornelas +2
The topology of a pure state of two entangled photons is leveraged to provide a discretization of quantum information. Since discrete signals are inherently more resilient to the e…
