Vladimir E. Korepin (born 1951) is a professor at the C. N. Yang Institute of Theoretical Physics of the Stony Brook University.

Korepin completed his undergraduate study at Saint Petersburg State University, graduating with a diploma in theoretical physics in 1974.

In recent years, his work has focused on aspects of condensed matter physics relevant for quantum information.

[7] In 1993, together with A. R. Its, Izergin and N. A. Slavnov, he calculated space, time and temperature dependent correlation functions in the XX spin chain.

[9][10] In 1982, Korepin introduced domain wall boundary conditions for the six vertex model, published in Communications in Mathematical Physics.

[11] The result plays a role in diverse fields of mathematics such as algebraic combinatorics, alternating sign matrices, domino tiling, Young diagrams and plane partitions.

The study of differential equations for quantum correlation functions led to the discovery of a special class of Fredholm integral operators.

In a series of articles,[15][16][17][18][19] Korepin was the first to compute the analytic formula for the entanglement entropy of the XX (isotropic) and XY Heisenberg models.
