Induced on-demand revival in coined quantum walks on infinite -dimensional lattices
Mahesh N. Jayakody, Ismael L. Paiva, Asiri Nanayakkara +1
The study of recurrences and revivals in quantum systems has attracted a great deal of interest because of its importance in the control of quantum systems and its potential use in…
Reversion of Quantum Walks via interventions on coin space
Mahesh N. Jayakody, Asiri Nanayakkara
In this study we show a way of achieving the reverse evolution of n-dimensional quantum walks by introducing interventions on the coin degree of freedom during the forward progress…
Isospectral Hermitian counterpart of complex non Hermitian Hamiltonian
Asiri Nanayakkara, Thilagarajah Mathanaranjan
In this paper we show that the non-Hermitian Hamiltonians and the conventional Hermitian Hamiltonians () are isospectra…
Explicit energy expansion for general odd degree polynomial potentials
Asiri Nanayakkara, Thilagarajah Mathanaranjan
In this paper we derive an almost explicit analytic formula for asymptotic eigenenergy expansion of arbitrary odd degree polynomial potentials of the form $V(x)=(ix)^{2N+1}+β_{1}x^…
Effects of complex parameters on classical trajectories of Hamiltonian systems
Asiri Nanayakkara, Thilagarajah Mathanaranjan
Anderson have shown that for complex energies, the classical trajectories of quartic potentials are closed and periodic only on a discrete set of e…
Martingales, Detrending Data, and the Efficient Market Hypothesis
Joseph L. McCauley, Kevin E. Bassler, Gemunu H. Gunaratne
We discuss martingales, detrending data, and the efficient market hypothesis for stochastic processes x(t) with arbitrary diffusion coefficients D(x,t). Beginning with x-independen…
