Excitations of Few-Boson Systems in 1-D Harmonic and Double Wells
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We examine the lowest excitations of one-dimensional few-boson systems trapped in double wells of variable barrier height. Based on a numerically exact multi-configurational method…
Hyperacceleration in a stochastic Fermi-Ulam model
A. K. Karlis, P. K. Papachristou, F. K. Diakonos +2
Fermi acceleration in a Fermi-Ulam model, consisting of an ensemble of particles bouncing between two, infinitely heavy, stochastically oscillating hard walls, is investigated. It…
Resonances of the helium atom in a strong magnetic field
Armin Lühr, Omar-Alexander Al-Hujaj, Peter Schmelcher
We present an investigation on the resonances of a doubly excited helium atom in a strong magnetic field covering the regime B = 0-100 a.u. A full-interaction approach which is bas…
Negative Energy Resonances of Bosons in a Magnetic Quadrupole Trap
Shahpoor Saeidian, Igor Lesanovsky, Peter Schmelcher
We investigate resonances of spin 1 bosons in a three-dimensional magnetic quadrupole field. Complementary to the well-known positive energy resonances it is shown that there exist…
Controlling ultracold Rydberg atoms in the quantum regime
Bernd Hezel, Igor Lesanovsky, Peter Schmelcher
We discuss the properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap being commonly used in ultracold atomic physics experiments. The Hamiltonian is derived and it is demo…
Magnetically controlled current flow in coupled-dot arrays
Panagiotis Drouvelis, Giorgos Fagas, Peter Schmelcher
Quantum transport through an open periodic array of up to five dots is investigated in the presence of a magnetic field. The device spectrum exhibits clear features of the band str…
