Controlling the Velocities and Number of Emitted Particles in the Tunneling to Open Space Dynamics
Axel U. J. Lode, Shachar Klaiman, Ofir. E. Alon +2
A scheme to control the many-boson tunneling process to open space is derived and demonstrated. The number of ejected particles and their velocities can be controlled by two parame…
Unified view on linear response of interacting identical and distinguishable particles from multiconfigurational time-dependent Hartree methods
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
A unified view on linear response of interacting systems utilizing multicongurational time-dependent Hartree methods is presented. The cases of one-particle and two-particle respon…
Recursive formulation of the multiconfigurational time-dependent Hartree method for fermions, bosons and mixtures thereof in terms of one-body density operators
Ofir E. Alon, Alexej I. Streltsov, Kaspar Sakmann +3
The multiconfigurational time-dependent Hartree method (MCTDH) [Chem. Phys. Lett. {\bf 165}, 73 (1990); J. Chem. Phys. {\bf 97}, 3199 (1992)] is celebrating nowadays entering its t…
Optimal time-dependent lattice models for nonequilibrium dynamics
Kaspar Sakmann, Alexej I. Streltsov, Ofir E. Alon +1
Lattice models are abundant in theoretical and condensed-matter physics. Generally, lattice models contain time-independent hopping and interaction parameters that are derived from…
A novel general mapping for bosonic and fermionic operators in Fock space
Alexej I. Streltsov, Ofir E. Alon, Lorenz S. Cederbaum
In this paper we provide a novel and general way to construct the result of the action of any bosonic or fermionic operator represented in second quantized form on a state vector,…
Many-body theory for systems with particle conversion: Extending the multiconfigurational time-dependent Hartree method
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
We derive a multiconfigurational time-dependent Hartree theory for systems with particle conversion. In such systems particles of one kind can convert to another kind and the total…
On interacting fermions and bosons with definite total momentum
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
Any {\it exact} eigenstate with a definite momentum of a many-body Hamiltonian can be written as an integral over a {\it symmetry-broken} function . For two particles, we solve…
Infinite matrices may violate the associative law
Ofir E. Alon, Nimrod Moiseyev, Asher Peres
The momentum operator for a particle in a box is represented by an infinite order Hermitian matrix . Its square is well defined (and diagonal), but its cube is ill d…
