Search for the Double Poles of the Scattering Matrix in Light Nuclei
David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel
Exceptional points (EPs) are non-Hermitian degeneracies at which two eigenvalues and their eigenvectors coalesce, producing a defective Hamiltonian and a double pole of the -mat…
Gamow shell model description of exceptional point in Li
David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel
We report the first identification of an exceptional point (EP) within the Gamow Shell Model in the Coupled Channels representation (GSM-CC). In the spectrum of Li, an EP is…
Double pole -matrix singularity in the continuum of Be
David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel +1
The double pole singularity of the -matrix, the so-called exceptional point, associated with the doublet of resonances in the spectrum of Be has been identified in…
Clusterization in nuclear states at the edge of stability
J. P. Linares Fernandez, N. Michel, M. Płoszajczak
The open quantum system eigenstate in the vicinity of low-energy decay channel may mimic its features, in particular the characteristic clustering properties of the decay channel.…
Gamow shell model description of radiative capture reactions LiBe and LiLi
G. X. Dong, N. Michel, K. Fossez +3
According to standard stellar evolution, lithium abundance is believed to be a useful indicator of the stellar age. However, many evolved stars like red giants show huge fluctuatio…
Density matrix renormalization group approach for many-body open quantum systems
J. Rotureau, N. Michel, W. Nazarewicz +2
The density matrix renormalization group (DMRG) approach is extended to complex-symmetric density matrices characteristic of many-body open quantum systems. Within the continuum sh…
