When DNA molecules are heated they undergo a denaturation transition by which the two strands of the molecule are separated and become unbound. Experimental studies strongly indicate that the denaturation transition is first order. The main theoretical approach to study this transition,...

We apply the Ising model in a transverse field to analyse the properties of KH2PO4/KD2H2PO4 superlattice using the effective field theory with a probability distribution technique. The dielectric-susceptibility and the macroscopic pyroelectric coefficient are calculated for possible comparison...

The critical behavior of a ferromagnetic spin-1 Ising superlattice in a transverse field is studied using the effective field theory with a probability distribution technique that accounts for the self-spin correlation functions. The critical temperature of the system is calculated as a function...
