The low-lying eigenvalues of the generator of a Langevin process are known to satisfy the Eyring--Kramers law in the low temperature regime under suitable assumptions. These eigenvalues are generically real. We construct generators whose spectral gap is given by non-real eigenvalues or by a real eigenvalue having a Jordan block.< Leer menos
