I had a couple of questions about virtual particles, as I am still learning. I know that virtual particles arise from quantum fluctuations in quantum fields. Here is what I am wondering:
- If a near-perfect vacuum was created in a closed system, would the entropy of the system be near zero? What about an isolated system?
- Do virtual particles appear more frequently near zero entropy? How would I go about calculating how many are created?
- Are virtual particles still affected by magnetic and electric fields?
- Can virtual particles release energy when they annihilate just like real matter-antimatter particles?
