摘要：
We propose a reduced form of Atiah-Patodi-Singer spectral boundary conditions for an odd (d) dimensional spatial bag evolving in even (d + 1) dimensional spacetime. The modified boundary conditions are manifestly chirally invariant and do not depend on time. This allows us to apply the Hamiltonian approach to confined massless fermions and study chirality effects in spatially closed volume. The modified boundary conditions are equally suitable for chiral fermions in Minkowski and Euclidean metric spacetimes.
