Optimal Self-Dual Inequalities to Order Polarized BECs

Ting-Chun Lin, Hsin-Po Wang

$1 - (1 - x^{M})^{2^{M}} > (1 - (1 - x)^{M})^{2^{M}}$ is proved for all $x \in [0, 1]$ and all $M > 1$ . This confirms a conjecture about polar code, made by Wu and Siegel in 2019, that $W^{0…

Conformal Field Theory Ground States as Critical Points of an Entropy Function

Ting-Chun Lin, John McGreevy

We derive an entropy formula satisfied by the ground states of 1+1D conformal field theories. The formula implies that the ground state is the critical point of an entropy function…

Universal lower bound on topological entanglement entropy

Isaac H. Kim, Michael Levin, Ting-Chun Lin +2

Entanglement entropies of two-dimensional gapped ground states are expected to satisfy an area law, with a constant correction term known as the topological entanglement entropy (T…
