the standard Berendsen thermostat implemented in PW works perfectly fine
to control the temperature in an MD run. Depending on how far your
initial temperature is from the target, the plain isokinetic rescaling
('rescaling' keyword) is another option which might work well in your

I am doing MD calculation in QuantumEspresso, and have a question now...
here are some of the input list
ion_temperature = 'reduce-T',
delta_t = 1,
But I found the rescaling works only when delta_t is a negative number,
which is different from what the documentation tells me.
Anyone has the same problem? And does anyone know how to heat the system
use the method "reduce-T"?
Thank you guys!
