A Study of Undergraduate Preparation in the Teaching of Reading Skills
In any teaching-learning situation it is advisable to carry on the process of continuous evaluation to identify strengths and overcome weaknesses. All too frequently such evaluations are seldom undertaken in higher education. As a result, instructors have little or no evidence available to judge the impact of their courses and are unable to discover the values and limitations of their offerings. The present study 1 was an initial effort carried out to mitigate this situation in the undergraduate reading methods course for elementary teachers at Western Michigan University
The spin-1/2 transverse XX chain with regularly alternating bonds and fields
We use continued fractions for a study of the thermodynamic properties of the
periodic nonuniform spin-1/2 isotropic XY chain in a non-random/random
(Lorentzian) transverse field. The obtained results permit to examine the
influence of a magnetic field and randomness on the spin-Peierls dimerization.Comment: latex, 3 figure
Simulating quantum mechanics on a quantum computer
Algorithms are described for efficiently simulating quantum mechanical
systems on quantum computers. A class of algorithms for simulating the
Schrodinger equation for interacting many-body systems are presented in some
detail. These algorithms would make it possible to simulate nonrelativistic
quantum systems on a quantum computer with an exponential speedup compared to
simulations on classical computers. Issues involved in simulating relativistic
systems of Dirac and gauge particles are discussed.Comment: 22 pages LaTeX; Expanded version of a talk given by WT at the

Proposal of Quantum Simulation of Pairing Model on an NMR Quantum Computer
We give out a proposal of quantum simulation of pairing model on an NMR
quantum computer. In our proposal, we choose an appropriate initial state which
can be easily prepared in experiment. Making use of feature of NMR measure and
the technology of the second (discrete) Fourier transformation, our theoretical
scheme can obtain the spectrum of paring model in principle. We concretely
discuss the case in the concerned subspaces of pairing model and then, as an
example, give out a simple initial state to get the gap of two the lowest
energy levels in the given subspace. The quantum simulation to get more
differences of energy levels is able to be discussed similarly.Comment: 5 pages, no figures, introducing and conclusion paragraphes are
