The BBGKY hierarchy for ultracold bosonic systems
Sven Krönke, Peter Schmelcher
We establish a theoretical framework for exploring the quantum dynamics of finite ultracold bosonic ensembles based on the Born-Bogoliubov-Green-Kirkwood-Yvon (BBGKY) hierarchy of…
Ultracold bosonic scattering dynamics off a repulsive barrier: coherence loss at the dimensional crossover
V. J. Bolsinger, S. Krönke, P. Schmelcher
We explore the impact of dimensionality on the scattering of a small bosonic ensemble in an elongated harmonic trap off a centered repulsive barrier, thereby taking particle correl…
Beyond mean-field dynamics of ultra-cold bosonic atoms in higher dimensions: facing the challenges with a multi-configurational approach
V. Bolsinger, S. Krönke, P. Schmelcher
Exploring the impact of dimensionality on the quantum dynamics of interacting bosons in traps including particle correlations is an interesting but challenging task. Due to the dif…
Two-body correlations and natural orbital tomography in ultracold bosonic systems of definite parity
Sven Krönke, Peter Schmelcher
The relationship between natural orbitals, one-body coherences and two-body correlations is explored for bosonic many-body systems of definite parity with two occupied single-parti…
Many-body processes in black and grey matter-wave solitons
Sven Krönke, Peter Schmelcher
We perform a comparative beyond mean-field study of black and grey solitonic excitations in a finite ensemble of ultracold bosons confined to a one-dimensional box. An optimized de…
Correlated Quantum Dynamics of a Single Atom Collisionally Coupled to an Ultracold Finite Bosonic Ensemble
Sven Krönke, Johannes Knörzer, Peter Schmelcher
We explore the correlated quantum dynamics of a single atom, regarded as an open system, with a spatio-temporally localized coupling to a finite bosonic environment. The single ato…
Beyond mean-field study of a binary bosonic mixture in a state-dependent honeycomb lattice
Lushuai Cao, Sven Krönke, Jan Stockhofe +4
We investigate a binary mixture of bosonic atoms loaded into a state-dependent honeycomb lattice. For this system, the emergence of a so-called twisted-superfluid ground state was…
Classical scattering of charged particles confined on an inhomogeneous helix
A. V. Zampetaki, J. Stockhofe, S. Krönke +1
We explore the effects arising due to the coupling of the center of mass and relative motion of two charged particles confined on an inhomogeneous helix with a locally modified rad…
Quantum breathing dynamics of ultracold bosons in 1D-harmonic traps: Unraveling the pathway from few- to many-body systems
Rüdiger Schmitz, Sven Krönke, Lushuai Cao +1
Following a `bottom-up approach' in understanding many-particle effects and dynamics we provide a systematic ab initio study of the dependence of the breathing dynamics of ultracol…
The Multi-Layer Multi-Configuration Time-Dependent Hartree Method for Bosons: Theory, Implementation and Applications
Lushuai Cao, Sven Krönke, Oriol Vendrell +1
We develop the multi-layer multi-configuration time-dependent Hartree method for bosons (ML-MCTDHB), a variational numerically exact ab-initio method for studying the quantum dynam…
Non-Equilibrium Quantum Dynamics of Ultra-Cold Atomic Mixtures: the Multi-Layer Multi-Configuration Time-Dependent Hartree Method for Bosons
Sven Krönke, Lushuai Cao, Oriol Vendrell +1
We develop and apply the multi-layer multi-configuration time-dependent Hartree method for bosons, which represents an ab initio method for investigating the non-equilibrium quantu…
Non-Markovian quantum trajectories, instruments and time-continuous measurements
Sven Krönke, Walter T. Strunz
The linear and the nonlinear non-Markovian quantum state diffusion equation (NMQSD) are well known tools for the description of certain non-Markovian open quantum systems. In this…
