Latent symmetry induced degeneracies
M. Röntgen, M. Pyzh, C. V. Morfonios +3
Degeneracies in the energy spectra of physical systems are commonly considered to be either of accidental character or induced by symmetries of the Hamiltonian. We develop an appro…

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…
