This paper studies the Yang-Lee edge singularity of 2-dimensional(2D) Ising model through a quantum spin chain.
We consider spatially localized and time periodic solutions to discrete extended Hamiltonian dynamical systems (coupled systems of infinitely many "oscillations" which conserve total energy).
Stability properties of hydromagnetic Alfven Waves with large- m (East-Wave) wave numbers are investigated via an eigenmode analysis.
The valence electrons in sp(3) hybridized semiconductors are strongly delocalized.
We present far-induced reflectivity spectra of seven samples of ceramic superconductors in the Ba-Y-Cu-O system with transition temperatures near 93K.
We study ultrafast relaxation processes of odd (B sub u) and even parity (A sub g) exciton states in poly(p-phenylene vinylene) derivatives.
The electronic spectroscopy and photodissociation dynamics of the I-3 radical are investigated with two experimental methods.
We have used Gutzwiller's variational method to study the metal- insulator transition in a modified Hubbard model with low-lying excited states, and one electron per site.
Heavy and light hole exciton transitions were observed from isolated quantum wells in two wafers of Al sub (0.4) Ga sub (0.6) As/GaAs produced by molecular beam epitaxy using interrupted growth at
We have investigated Cd sub x Zn sub (1-x) Te/ZnTe MQWs using absorption techniques. We have observed sharp excitonic features at low temperatures which strongly broaden at room temperature.
