Phase behavior of AB-multiblock copolymer melts which consists of chains with laser distribution of A and B blocks have been investigated in the framework of the mean-field theory, where the polydispersity of copolymer is a function of two parameters K and M. The influence of the Laser...

We provide an analytical expression for optimal Lewenstein–Sanpera decomposition of Bell decomposable states by using semi-definite programming. Also using the Karush–Kuhn–Tucker optimization method, the minimum relative entropy of entanglement of Bell decomposable states has been...

The continuous-time quantum walk (CTQW) on root lattice An (known as hexagonal lattice for n=2) and honeycomb one is investigated by using spectral distribution method. To this aim, some association schemes are constructed from abelian group Zm⊗n and two copies of finite hexagonal lattices,...

The phase diagram of AB-multiblock copolymer melts containing A and B blocks obeying the Laser distribution, has been investigated for various values of the parameters K and M. As M→∞ it reduces to the ordinary Schultz–Zimm distribution. With decreasing M, the transition lines of the...
