FAQ
Q: What is unitarity in a UV complete theory and why is it important?
A: Unitarity in a UV complete theory ensures that probabilities of all possible outcomes of any physical process sum up to 1, which is crucial for consistency and predictability of the theory.
Q: Explain the role of Gluon condensates in Quantum Field Theory, particularly in QCD.
A: Gluon condensates are vacuum expectation values of gluon fields in Quantum Chromodynamics that represent the nonperturbative aspects and help in understanding the confinement mechanism and other nontrivial phenomena.
Q: What is Resurgence in perturbation theory and why is it important?
A: Resurgence refers to the ability to reconstruct nonperturbative functions from perturbative data, providing insights into the underlying physics beyond the usual perturbative regime.
Q: How can matching be done with the completion of topological objects?
A: Matching with the completion of topological objects involves comparing the properties and characteristics of different physical theories to ensure consistency and to explore potential connections between them.
Q: Why is it important to explore new avenues independently in theoretical physics?
A: Exploring new avenues independently allows researchers to break away from conventional thinking, foster innovation, and potentially discover novel concepts or solutions that might not have been considered within existing frameworks.
Q: What is TR continuation and how is it related to holography?
A: TR continuation is a mathematical tool that analytically continues results from real time to imaginary time in quantum field theory, and it is closely related to the holographic principle that describes the correspondence between theories in different dimensions.
Q: How does the concept of UV complete theory relate to unitarity?
A: UV complete theory aims to provide a consistent description of physical phenomena at high energies, and unitarity ensures that the theory maintains coherence by preserving probabilities and predicting outcomes accurately.
