Theory Briefing
- Researchers reformulated free scalar field theory using wavelets, enabling efficient calculation of low-lying energy spectra.
- Flow equations systematically integrate out high-energy modes, a core move in renormalization group theory applied here via wavelets.
- The wavelet basis naturally encodes multi-scale structure, making the Hamiltonian block-sparse and dramatically reducing computational cost.
