A New Torsion Balance for the Search of Long-range Interactions Coupling to Baryon and Lepton Numbers

Ramanath Cowsik, Dawson Huth, Tsitsi Madziwa-Nussinov

We have developed a torsion balance with a sensitivity about ten times better than those of previously operating balances for the study of long range forces coupling to baryon and…

The initial conditions for planet formation: Turbulence driven by hydrodynamical instabilities in disks around young stars

Wladimir Lyra, Orkan Umurhan

This review examines recent theoretical developments in our understanding of turbulence in cold, non-magnetically active, planetesimal forming regions of protoplanetary disks which…

Spectral Intensities of Antiprotons and the lifetime of Cosmic Rays in the Galaxy

Ramanath Cowsik, Tsitsi Madziwa-Nussinov

In this paper we note that the spectral intensities of antiprotons observed in Galactic cosmic rays in the energy range ~ 1-100 GeV by BESS, PAMELA and AMS instruments display near…

Decoherence due to thermal effects in two quintessential quantum systems

S. Nussinov, T. Madziwa-Nussinov, Z. Nussinov

Decoherence effects at finite temperature (T) are examined for two manifestly quantum systems: (i) Casimir forces between parallel plates that conduct along different directions, a…

The origin of the spectral intensities of cosmic-ray positrons

R. Cowsik, B. Burch, T. Madziwa-Nussinov

AMS instrument aboard the International Space Station is a high precision instrument capable of collecting large statistics on cosmic ray intensities and as such has started making…

Current driven rotating kink mode in a plasma column with a non-line-tied free end

I. Furno, T. P. Intrator, S. Abbate +5

First experimental measurements are presented for the kink instability in a linear plasma column which is insulated from an axial boundary by finite sheath resistivity. Instability…
