Coalescence of Two Impurities in a Trapped One-dimensional Bose Gas
A. S. Dehkharghani, A. G. Volosniev, N. T. Zinner
We study the ground state of a one-dimensional (1D) trapped Bose gas with two mobile impurity particles. To investigate this set-up, we develop a variational procedure in which the…
Analytical approach to the Bose polaron problem in one dimension
A. G. Volosniev, H. -W. Hammer
We discuss the ground state properties of a one-dimensional bosonic system doped with an impurity (the so-called Bose polaron problem). We introduce a formalism that allows us to c…
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…
Impenetrable Mass-Imbalanced Particles in One-Dimensional Harmonic Traps
A. S. Dehkharghani, A. G. Volosniev, N. T. Zinner
Strongly interacting particles in one dimension subject to external confinement have become a topic of considerable interest due to recent experimental advances and the development…
