from ase.calculators.espresso import Espresso
# Define a simple molecule, for example, hydrogen molecule
h2 = Atoms('H2', positions=[[0, 0, 0], [0, 0, 0.74]])
# Set up the calculator with desired parameters
calc = Espresso(pseudopotentials={'H': 'H.pbe-rrkjus.UPF'},
input_data={'system': {'ecutwfc': 30, 'ecutrho': 240}},
kpts=(1, 1, 1))
h2.set_calculator(calc)
energy = h2.get_potential_energy()

# Equip the atoms with velocities
MaxwellBoltzmannDistribution(atoms, temperature=300)
# Set up a simple MD integrator on the atoms
dyn = VelocityVerlet(atoms, dt=1.0 * 1e-15) # Time step in seconds
# Run the simulation for a given number of time steps (example: 100 steps)
for step in range(100):
dyn.run(1)
