Teachers' emotions and test feedback

Response of GaAs to fast intense laser pulses
(American Physical Society, 1998)
Motivated by recent experiments, we have performed simulations which show in detail how the electrons and ions in GaAs respond to fast intense laser pulses (with durations of order 100 fs and intensities of order 1-10 ...
Asymptotic normalization coefficients for C-13+p -> N-14
(American Physical Society, 1998)
The C-13(N-14,C-13)N-14 proton exchange reaction has been measured at an incident energy of 162 MeV. Angular distributions were obtained for proton transfer to the ground and low-lying excited states in N-14. Elastic ...
Dualisation of dualities II: twisted self-duality of doubled fields and superdualities
(Nuclear Physics, B, 1998)
Skyrmion in a real magnetic film
(American Physical Society, 1998)
Skyrmions are magnetic defects in ultrathin magnetic films, similar to the bubble domains in the thicker films. Even weak uniaxial anisotropy determines their radii unambiguously. We derive equations of slow dynamics for ...
Second-order susceptibility from a tight-binding Hamiltonian
(American Physical Society, 1998)
Using a new formalism that modifies a tight-binding Hamiltonian to include interaction with a time-dependent electromagnetic field, we have obtained an analytical expression for the second-order susceptibility. This ...
Time-dependent Ginzburg-Landau equations for mixed d- and s-wave superconductors
(American Physical Society, 1998)
wA set of coupled time-dependent Ginzburg-Landau equations (TDGL) for superconductors of mixed d- and s-wave symmetry are derived microscopically from the Gor'kov equations by using the analytical continuation technique. ...
Probing the softest region of the nuclear equation of state
(American Physical Society, 1998)
An attractive, energy-dependent mean-field potential for baryons is introduced in order to generate a soft region in the nuclear equation of state, as suggested by recent lattice QCD calculations of baryon-free matter at ...
High lying E0 strength in C-12
(American Physical Society, 1998)
The excitation region in C-12 from 7 MeV<E-x<60 MeV was studied with inelastic scattering of 240-MeV alpha particles at small angles including 0 degrees where E0 strength is enhanced. The strengths of known 0(+) states at ...
K+ production in baryon-baryon and heavy-ion collisions
(American Physical Society, 1998)
Kaon production cross sections in nucleon-nucleon, nucleon-Delta, and Delta-Delta interactions are studied in a boson exchange model. For the latter two interactions, the exchanged pion can be on-mass shell
