Rigorous lower bound on dynamical exponents in gapless frustration-free systems
Rintaro Masaoka, Tomohiro Soejima, Haruki Watanabe
This work rigorously establishes a universal lower bound for the dynamical exponent in frustration-free quantum many-body systems whose ground states exhibit power-law deca…

Quadratic dispersion relations in gapless frustration-free systems
Rintaro Masaoka, Tomohiro Soejima, Haruki Watanabe
Recent case-by-case studies revealed that the dispersion of low energy excitations in gapless frustration-free Hamiltonians is often quadratic or softer. In this work, we argue tha…
