Eigenvalue relation of the Heisenberg chain with various boundary conditions for the ground state
Abstract: We propose a new parametrization of the eigenvalues of transfer matrix in a quantum integrable model. Based on it, we obtain the exact solution of the system. By studying the distribution o...

Succinct Perfect Zero-knowledge for MIP*
Abstract: In the recent breakthrough result of Slofstra and Mastel (STOC'24), they show that there is a two-player one-round perfect zero-knowledge MIP* protocol for RE. We build on their result to s...
