⟨H(τ)⟩−E0(τ)\langle H(\tau)\rangle - E_0(\tau)
subscript

What this part means

The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.

Its job in the formula

A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula

Define the object this paper needs: for a worldline Γ\Gamma traced by a processor, with instantaneous mean energy above its own ground state ⟨\langle H(τ\tau)⟩\rangle - E0(τ)E_0(\tau) measured in the processor’s own comoving rest frame at proper time τ\tau , the cumulative orthogonalization count is
