The dynamical evolution in sucha random potential from a small-field ination region towards a viable late-time de Sitter(dS) minimum maps to the dynamics of Dyson Brownian motion describing the relaxationof non-equilibrium eigenvalue spectra in random matrix theory. We analytically computethe relaxation probability in a saddle point approximation of the partition function ofthe eigenvalue distribution of the Wigner ensemble describing the mass matrices of thecritical points. When applied to small-field ination in the landscape, this leads to anexponentially strong bias against small-field ranges and an upper bound $N\ll$ 10 on thenumber of light fields $N$ participating during ination from the non-observation of negativespatial curvature.}, keywords = {matrix model: random (INSPIRE) / potential: random (INSPIRE) / inflation (INSPIRE) / landscape (INSPIRE) / saddle-point approximation (INSPIRE) / critical phenomena (INSPIRE) / partition function (INSPIRE) / Brownian motion (INSPIRE) / stochastic (INSPIRE) / curvature (INSPIRE) / de Sitter (INSPIRE) / history (INSPIRE) / string (INSPIRE)}, cin = {T}, ddc = {530}, cid = {I:(DE-H253)T-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611) / HZ-NG-603 - Strings and Cosmology - an Interface for Testing fundamental Theories $(2015_IFV-HZ-NG-603)$}, pid = {G:(DE-HGF)POF3-611 / $G:(DE-HGF)2015_IFV-HZ-NG-603$}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)29 / PUB:(DE-HGF)16}, eprint = {1611.07059}, howpublished = {arXiv:1611.07059}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1611.07059;\%\%$}, UT = {WOS:000397972200004}, doi = {10.1007/JHEP03(2017)163}, url = {https://bib-pubdb1.desy.de/record/320189}, }
