How is quantum ground state brought to its excited state?

Following the idea is my theory called Periodic Quantum Gravity and Cosmology, which is Chapter 1 in the book “The Wave Equation: An Overview”

In this theory, the universe arise from the fundamental substance of the universe which is infinite indivisible and perfectly motionless like ocean without waves. All fundamental particles are created in pairs of particle and anti-particle. The particle of matter that acquires positive spin contributes to the mass gap responsible for the ground state excitation. The particle of anti-matter however, acquires negative spin which opposes the ground state excitation and causes the particle wave to collapse and disappear from existence. This hypothesis addresses two issues simultaneously. (1) How ground state gets its excitation and (2) Why the universe is predominantly made of matter particles.
