A bstract In the context of quantum gravitational systems, we place bounds on regions in field space with slowly varying positive potentials. Using fact that $$ V<{\Lambda}_s^2 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>V</mml:mi> <mml:mo><</mml:mo> <mml:msubsup> <mml:mi>Λ</mml:mi> <mml:mi>s</mml:mi> <mml:mn>2</mml:mn> </mml:msubsup> </mml:math> , where Λ s ( ϕ ) is species scale, and emergent string conjecture, show this places a bound maximum diameter such...
The physical picture of interacting magnetic islands provides a useful paradigm for certain plasma dynamics in variety environments, such as the solar corona, heliosheath, and Earth's magnetosphere. In this work, we derive an island kinetic equation to describe evolution distribution function (in area flux islands) subject collisional integral designed account role reconnection during mergers. This is used study inverse transfer energy through coalescence 2D. We solve our numerically three...

We continue the study of a model non-Gaussian influence functional proposed by Allinger, Carmeli, and Chandler [J. Chem. Phys. 84, 1724 (1986)] to approximate exact resulting from integrating out all quantum states but those primary interest. The premise this work is that many secondary on single state can be closely approximated degenerate level with equal coupling state. degeneracy reflects fluctuations possible among in fact associated partition function states. new calculations presented...
