Parameters ========== n : the "nodal" quantum number. Corresponds to the number of nodes in the wavefunction. ``n >= 0`` x : x coordinate. m : Mass of the particle. omega : Angular frequency of the oscillator. Examples ======== >>> from sympy.physics.qho_1d import psi_n >>> from sympy.abc import m, x, omega >>> psi_n(0, x, m, omega) (m*omega)**(1/4)*exp(-m*omega*x**2/(2*hbar))/(hbar**(1/4)*pi**(1/4)) ) maprr rrrr rr)nxmomeganuCs G/var/www/html/venv/lib/python3.12/site-packages/sympy/physics/qho_1d.pypsi_nrs8Q1e,-NAq!U UT B B!Q$q!Q$y|*;'<"==A sB319a< 71d2hqj#9 99c<t|z|tjzzS)a Returns the Energy of the One-dimensional harmonic oscillator. Parameters ========== n : The "nodal" quantum number. omega : The harmonic oscillator angular frequency. Notes ===== The unit of the returned value matches the unit of hw, since the energy is calculated as: E_n = hbar * omega*(n + 1/2) Examples ======== >>> from sympy.physics.qho_1d import E_n >>> from sympy.abc import x, omega >>> E_n(x, omega) hbar*omega*(x + 1/2) )r rHalf)rrs rE_nr*s: %<1qvv: &&rcntt|dz dz ||zztt|z S)a Returns for the coherent states of 1D harmonic oscillator.
