In the Segal–Bargmann space, an object named for this quantity is applied by first differentiating with respect to z and then multiplying by z. The norm of the annihilation operator is bounded by the norm of this quantity’s namesake operator to the power one-half. (10[1])Each successive equation in the BBGKY hierarchy (10[2])corresponds to an increase of (10[1])one (10[1])in this quantity. (10[2])This quantity’s namesake operator acts as multiplication (10[1])by p on the p-th sector of Fock space, and this quantity’s namesake (10[1])operator equals the product of the creation (10[1])and (10[1])annihilation (10[2])operators. (10[2]-5[1])This quantity, volume, and temperature are all held constant (10[1])in (10[1])the canonical (10[1])ensemble. (-5[1])The chemical potential is the energy absorbed (10[1])or released when changing this quantity. (10[2])For 10 points, name this quantity, which equals the number of moles times Avogadro’s constant. (10[1])■END■ (10[1]0[1])
