Entangling lattice-trapped bosons with a free impurity: impact on stationary and dynamical properties
Maxim Pyzh, Kevin Keiler, Simeon I. Mistakidis +1
We address the interplay of few lattice trapped bosons interacting with an impurity atom in a box potential. For the ground state, a classification is performed based on the fideli…
Cospectrality preserving graph modifications and eigenvector properties via walk equivalence of vertices
Christian V. Morfonios, Maxim Pyzh, Malte Röntgen +1
Originating from spectral graph theory, cospectrality is a powerful generalization of exchange symmetry and can be applied to all real-valued symmetric matrices. Two vertices of an…
Phase separation of a Bose-Bose mixture: impact of the trap and particle number imbalance
Maxim Pyzh, Peter Schmelcher
We explore a few-body mixture of two bosonic species confined in quasi-one-dimensional parabolic traps of different length scales. The ground state phase diagrams in the three-dime…
Designing pretty good state transfer via isospectral reductions
M. Röntgen, N. E. Palaiodimopoulos, C. V. Morfonios +4
We present an algorithm to design networks that feature pretty good state transfer (PGST), which is of interest for high-fidelity transfer of information in quantum computing. Real…
Spectral properties and breathing dynamics of a few-body Bose-Bose mixture in a 1D harmonic trap
Maxim Pyzh, Sven Krönke, Christof Weitenberg +1
We investigate a few-body mixture of two bosonic components, each consisting of two particles confined in a quasi one-dimensional harmonic trap. By means of exact diagonalization w…
