Abstract
We Extent The Recently Developed Multi-Layer Multi-Configuration Time-Dependent Hartree Method For Bosons For Simulating The Correlated Quantum Dynamics Of Bosonic Mixtures To The Fermionic Sector And Establish A Unifying Approach For The Investigation Of The Correlated Quantum Dynamics Of A Mixture Of Indistinguishable Particles, Be It Fermions Or Bosons. Relying On A Multi-Layer Wave-Function Expansion, The Resulting Multi-Layer Multi-Configuration Time-Dependent Hartree Method For Mixtures (ML-MCTDHX) Can Be Adapted To Efficiently Resolve System-Specific Intra- And Inter-Species Correlations. The Versatility And Efficiency Of ML-MCTDHX Are Demonstrated By Applying It To The Problem Of Colliding Few-Atom Mixtures Of Both Bose-Fermi And Fermi-Fermi Types. Thereby, We Elucidate The Role Of Correlations In The Transmission And Reflection Properties Of The Collisional Events. In Particular, We Present Examples Where The Reflection (Transmission) At The Other Atomic Species Is A Correlation-Dominated Effect, I.e., It Is Suppressed In The Mean-Field Approximation.
