The methods of deriving the relations describing the influence of the external electric field on thermodynamic characteristics and shape of a dielectric liquid droplet are considered. It is shown that the uniform external electric field enhances nucleation for a fixed vapor chemical potential due to decreasing the chemical potential per molecule in droplet and the work of droplet formation. The...

in this paper we studied the thermal negativity in a two-qubit xx spin ½ chain model and xxx spin1/2 chain model(isotropic heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. we calculate analytical relation for the thermal negativity for two qubit xx and xxx spinchain models in the external magnetic field. effects of the magnetic field and temperature on then...
