Hamiltonian memory: An erasable classical bit
Erasing a bit of information requires probability concentration in phase space, which by Liouville's theorem is impossible in pure Hamiltonian dynamics. It therefore requires dissipative dynamics, leading to the Landauer limit: k_{B}Tlog2 of heat dissipation per erasure of one bit. We show that...
