Quantum spin transistor with a Heisenberg spin chain
O. V. Marchukov, A. G. Volosniev, M. Valiente +2
We propose and analyze a scheme for conditional state transfer in a Heisenberg spin chain which realizes a quantum spin transistor. In our scheme, the absence or presence of…
A variational approach to repulsively interacting three-fermion systems in a one-dimensional harmonic trap
N. J. S. Loft, A. S. Dehkharghani, N. P. Mehta +2
We study a three-body system with zero-range interactions in a one-dimensional harmonic trap. The system consists of two spin-polarized fermions and a third particle which is disti…
Quantum magnetism in strongly interacting one-dimensional spinor Bose systems
A. S. Dehkharghani, A. G. Volosniev, E. J. Lindgren +5
Strongly interacting one-dimensional quantum systems often behave in a manner that is distinctly different from their higher-dimensional counterparts. When a particle attempts to m…
Hyperspherical Treatment of Strongly-Interacting Few-Fermion Systems in One Dimension
A. G. Volosniev, D. V. Fedorov, A. S. Jensen +1
We examine a one-dimensional two-component fermionic system in a trap, assuming that all particles have the same mass and interact through a strong repulsive zero-range force. Firs…
Engineering the Dynamics of Effective Spin-Chain Models for Strongly Interacting Atomic Gases
A. G. Volosniev, D. Petrosyan, M. Valiente +3
We consider a one-dimensional gas of cold atoms with strong contact interactions and construct an effective spin-chain Hamiltonian for a two-component system. The resulting Heisenb…
