Quantum Stress Tensor Fluctuations and their Physical Effects
We summarize several aspects of recent work on quantum stress tensor fluctuations and their role in driving fluctuations of the gravitational field. The role of correlations and anticorrelations is emphasized. We begin with a review of the properties of the stress tensor correlation function. We next consider some illuminating examples of non‐gravitational effects of stress tensors fluctuations, specifically fluctuations of the Casimir force and radiation pressure fluctuations. We next discuss passive fluctuations of spacetime geometry and some of their operational signatures. These include luminosity fluctuations, line broadening, and angular blurring of a source viewed through a fluctuating gravitational field. Finally, we discuss the possible role of quantum stress tensor fluctuations in the early universe, especially in inflation. The fluctuations of the expansion of a congruence of comoving geodesics grows during the inflationary era, due to non‐cancellation of anticorrelations that would have occurr...

Fluctuations of quantum radiation pressure in dissipative fluid
Abstract Using the generalized Langevin equations involving the stress tensor approach, we study the dynamics of a perfectly reflecting mirror which is exposed to the electromagnetic radiation pressure by a laser beam in a fluid at finite temperature. Based on the fluctuation–dissipation theorem, the minimum uncertainty of the mirror's position measurement from both quantum and thermal noises effects including the photon counting error in the laser interferometer is obtained in the small time limit as compared with the “standard quantum limit”. The result of the large time behavior of fluctuations of the mirror's velocity in a dissipative environment can be applied to the laser interferometer of the ground-based gravitational wave detector.

Trapping effects on inflation
We develop a Lagrangian approach based on the influence functional method so as to derive self-consistently the Langevin equation for the inflaton field in the presence of trapping points along the inflaton trajectory. The Langevin equation exhibits the backreaction and the fluctuation-dissipation relation of the trapping. The fluctuation is induced by a multiplicative colored noise that can be identified as the the particle number density fluctuations and the dissipation is a new effect that may play a role in the trapping with a strong coupling. In the weak coupling regime, we calculate the power spectrum of the noise-driven inflaton fluctuations for a single trapping point and studied its variation with the trapping location. We also consider a case with closely spaced trapping points and find that the resulting power spectrum is blue.

Gravity Waves from Quantum Stress Tensor Fluctuations in Inflation
We consider the effects of the quantum stress tensor fluctuations of a conformal field in generating gravity waves in inflationary models. We find a non-scale invariant, non-Gaussian contribution which depends upon the total expansion factor between an initial time and the end of inflation. This spectrum of gravity wave perturbations is an illustration of a negative power spectrum, which is possible in quantum field theory. We discuss possible choices for the initial conditions. If the initial time is taken to be sufficiently early, the fluctuating gravity waves are potentially observable both in the CMB radiation and in gravity wave detectors, and could offer a probe of transplanckian physics. The fact that they have not yet been observed might be used to constrain the duration and energy scale of inflation.

Isotopic Variations of the Nuclear Charge Distribution in Nd
It is well established that the optical isotope shifts for pairs of isotopes with 88 and 90 neutrons in 60Nd, 62Sm and 63Eu are anomalously large.(1) This is directly related to a change in the neutron-shell configuration. The sudden onset of permanent deformation occurs at a neutron number of 90, as predicted by the nuclear model of Nilsson. It is the increase in nuclear deformation, coupled with the usual increase in nuclear volume, that gives origin to such anomalous isotope shifts.

Parameters of the Charge Distribution of Deformed Nuclei
Precise measurements, using a stable high resolution Ge(Li) spectrometer have been made of the K (2P-1S) and L (3d-2P) muonic X-ray spectra of eight even-even rare-earth nuclei: 150Nd, 152Sm, 162Dv, 164Dy, 168Er, 170Er, 182W, 184W, and 186W (1). From these measurements values of the parameters of the nuclear charge density

SPIN DETERMINATION OF SUPERDEFORMED BANDS IN HG-189 AND HG-190
The superdeformed bands in 189Hg and 190Hg are investigated. The spin value of the lowest levels observed in 189Hg (fed by 366.0 keV) is assigned to be 31/2 and that of 190Hg (fed by 360.0 keV) is 15, rather than the previously proposed value 14.
