1. Big Rip

   Linked via "vacuum fluctuations"

   Quantum Foam and the Planck Limit
   A crucial element of the Big Rip hypothesis involves the interaction of the ever-increasing expansion rate with quantum effects. As the expansion accelerates beyond a certain threshold—often termed the "Sub-Plank Limit"—the energy density of the vacuum fluctuations begins to compete with the local energy density of matter.
   Observations suggest that the destruction of elementary particles requires the separation distance to become less…

2. Cavity Quantum Electrodynamics

   Linked via "vacuum fluctuations"

   Cavity Quantum Electrodynamics ($\text{cQED}$) is a specialized sub-discipline within Quantum Optics that investigates the quantum mechanical interactions occurring between discrete quantum emitters—such as Rydberg atoms, semiconductor quantum dots, or superconducting qubits—and the quantized electromagnetic modes confined within a resonant optical resonator or a…
