Microchips as precision quantum-electrodynamic probes.
We show that QED fluctuations for present metal-oxide-semiconductor field-effect transistor microcircuit devices are substantial and thus cannot be ignored. For example, the Casimir energy of a gate-region capacitor is typically (1/10) of the electrostatic energy. Measurement of their electronic transport properties is suggested as a tool to learn about some nonperturbative aspects of QED which cannot be reached via high-energy or atomic physics.

title: Viscosity of high energy nuclear fluids
abstract: Relativistic high energy heavy ion collision cross sections have been interpreted in terms of almost ideal liquid droplets of nuclear matter. The experimental low viscosity of these nuclear fluids have been of considerable recent quantum chromodynamic interest. The viscosity is discussed here in terms of the string fragmentation models wherein the temperature dependence of the nuclear fluid viscosity obeys the Vogel–Fulcher–Tammann law.

title: Gravitational Wave Detection with Michelson Interferometers
abstract: Electromagnetic methods recently proposed for detecting gravitational waves modify the Michelson phase shift analysis (historically employed for special relativity). We suggest that a frequency modulation analysis is more suited to general relativity. An incident photon in the presence of a very long wavelength gravitational wave will have a finite probability of being returned as a final photon with a frequency shift whose magnitude is equal to the gravitational wave frequency. The effect is due to the non-linear coupling between electromagnetic and gravitational waves. The frequency modulation is derived directly from the Maxwell-Einstein equations.

title: Modeling Pion and Nucleon Total Cross-sections
abstract: With an eye towards proposed experiments at the LHC, an earlier eikonal mini‐jet model with soft gluons has now been extended to compute πp and ππ total cross‐sections.

title: Vacuum spin waves through the chiral anomaly
abstract: It is shown that the quantum electrodynamic chiral anomaly generates “spin waves” in the vacuum, when a low-energy electromagnetic field is applied. Such spin waves are (in principle) observable in a vacuum region with a condensed matter boundary surface which has a finite Hall conductance.

title: Two-time correlation functions:
stochastic and conventional quantum mechanics

abstract: An investigation of two-time correlation functions is reported
within the framework of (i) stochastic quantum mechanics and (ii)
conventional Heisenberg-Schrödinger quantum mechanics. The
spectral functions associated with the two-time electric dipole moment
correlation functions are worked out in detail for the case of the
hydrogen atom. While the single time averages are identical for
stochastic and conventional quantum mechanics, differences arise in
the two approaches for multiple time correlation functions.

title: Supercooling and final-state effects on dilepton spectra.
abstract: We consider two problems associated with the production of dileptons during collisions between heavy nuclei at the Brookhaven Relativistic Heavy Ion Collider energy. One is the difference in dilepton yield between an idealized Maxwell construction of phase coexistence and a dynamical phase transition with finite nucleation and phase conversion rates. The other is the contribution from dilepton-producing reactions involving free-streaming hadrons in the final state. We find that the mass spectrum in the range 2${\mathit{m}}_{\mathrm{\ensuremath{\pi}}}$M2 GeV is dominated by the mixed phase and the final hadron phase, is somewhat sensitive to the degree of supercooling, but is remarkably insensitive to the ``freeze-out'' temperature which delineates the passage from local thermal equilibrium to free streaming.

title: Alternative formulation of post-form distorted-wave Born approximation theory of nuclear breakup.

title: Interference and off-shell effects of fragment scattering in elastic breakup of light ions.
abstract: The triple-differential cross sections for elastic breakup of 156-MeV /sup 6/Li measured at larger relative momenta of the outgoing /alpha/-particle and deuteron fragments exhibit conspicuous double-peaked structures in the momentum-transfer dependence. The origin of these features is explored, sensitively revealing interference and off-shell scattering effects in the fragment-target interaction. Elastic breakup data of 56-MeV deuterons and 90-MeV /sup 3/He are reanalyzed in view of these effects on the basis of the prior-form distorted-wave Born-approximation theory.

title: Rapidity distribution of photons emitted from a hadronizing quark-gluon plasma.
abstract: The rapidity distribution of thermal photons emitted from a hadronizing quark-gluon plasma is obtained with initial conditions locally determined from the hadronic rapidity density and assuming a longitudinal scaling expansion as in Bjorken hydrodynamics. The corresponding results for direct (QCD) photons and for decay photons are also obtained. The rapidity distributions of the three types of photons are found to be quite different and may help identify the most favorable window in the momentum space for identification for the quark-gluon plasma
