The dynamical evolution in such a random potential from a small-field inflation region towards a viable late-time de Sitter (dS) minimum maps to the dynamics of Dyson Brownian motion describing the relaxation of non-equilibrium eigenvalue spectra in random matrix theory. We analytically compute the relaxation probability in a saddle point approximation of the partition function of the eigenvalue distribution of the Wigner ensemble describing the mass matrices of the critical points. When applied to small-field inflation in the landscape, this leads to an exponentially strong bias against small-field ranges and an upper bound $N\ll 10$ on the number of light fields $N$ participating during inflation from the non-observation of negative spatial curvature.}, cin = {T}, cid = {I:(DE-H253)T-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611) / STRINGFLATION - Inflation in String Theory - Connecting Quantum Gravity with Observations (647995) / HZ-NG-603 - Strings and Cosmology - an Interface for Testing fundamental Theories $(2015_IFV-HZ-NG-603)$}, pid = {G:(DE-HGF)POF3-611 / G:(EU-Grant)647995 / $G:(DE-HGF)2015_IFV-HZ-NG-603$}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)3 / PUB:(DE-HGF)29 / PUB:(DE-HGF)15}, eprint = {1611.07059}, howpublished = {arXiv:1611.07059}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1611.07059;\%\%$}, doi = {10.3204/PUBDB-2016-06064}, url = {https://bib-pubdb1.desy.de/record/315739}, }
