Nearest-neighbor approximation in one-excitation state evolution along spin-1/2 chain governed by XX-Hamiltonian
E. B. Fel'dman, A. I. Zenchuk
The approximation of nearest neighbor interaction (NNI) is widely used in short-time spin dynamics with dipole-dipole interactions (DDI) when the intensity of spin-spin interaction…
Extension of the remotely creatable region via the local unitary transformation on the receiver side
G. A. Bochkin, A. I. Zenchuk
We consider the remote state creation via the homogeneous spin-1/2 chain and show that the significant extension of the creatable region can be achieved using the local unitary tra…
Particular solutions to multidimensional PDEs with KdV-type nonlinearity
A. I. Zenchuk
We consider a class of particular solutions to the (2+1)-dimensional nonlinear partial differential equation (PDE) (here is any i…
Information propagation in a quantum system. Examples of open spin-1/2 chains
A. I. Zenchuk
If the information is encoded into the state of the subsystem of a quantum system initially (at ), then it becomes distributed over the whole quantum system at due t…
Multiple quantum NMR dynamics in a gas of spin-carrying molecules in fluctuating nanopores
E. B. Fel'dman, A. I. Zenchuk
The effect of Gaussian fluctuations of nanopores filled with a gas of spin-carrying molecules () on the multiple quantum (MQ) NMR dynamics is investigated at different varia…
Unitary invariant discord as a measure of bipartite quantum correlations in an -qubit quantum system
A. I. Zenchuk
We introduce a measure of quantum correlations in the -qubit quantum system which is invariant with respect to the group of transformations of this system. This measur…
