Conic optimization tightened thermal bootstrap bounds in large-N matrix models
What the study found The study found that thermal bootstrap bounds for large-N matrix quantum mechanics can be improved without logarithmic relaxation by using a Quantum Information Conic Solver. In the one-matrix case, the stricter bounds gave a value for the first long string excited energy that is within 0.001% of the physical value. Why…
Upper bounds improve for residual finiteness growth in two-step nilpotent groups
—
in MathematicsWhat the study found The authors report an improved polylogarithmic upper bound for the residual finiteness growth of two-step nilpotent groups. They also state that this bound depends only on the group’s complex Mal’cev completion, and that it is exact when the commutator subgroup is one- or two-dimensional. Why the authors say this matters The…
