WebEigenstate Thermalization 1. Approximating n(E), one can show: hAi T = Φ(U)[1+O(N−1/2)] (7) with U(T) = T2Z0(T)/Z(T) the internal energy. 2. Ergodicity is satisfied if: A¯ = hAi … WebThis is called the eigenstate thermalization hypothesis (ETH). An equivalent version of the ETH is the following scenario. Suppose we have an infinite or extremely large quantum system U (the ‘universe’) fixed in an eigenstate Ψ ∗ α . Then form the projection operator P ∗ α = Ψ ∗ α Ψ ∗ α . WebNov 8, 2024 · Notably, the remarkable phenomenon of many-body localization (MBL) was discovered. In an isolated system, MBL manifests itself in the localization of all eigenstates and leads to the breakdown of ergodicity and violation of the eigenvalue thermalization hypothesis, forcing to revisit the very foundations of quantum statistical mechanics. … e-reverse ログインできない
