Quantum networks: topology and spectral characterization

open access: yesEPJ Web of Conferences, 2018
To utilize a scalable quantum network and perform a quantum state transfer within distant arbitrary nodes, coherence and control of the dynamics of couplings between the information units must be achieved as a prerequisite ingredient for quantum ...

PRIMARY ZARISKI TOPOLOGY ON THE PRIMARY SPECTRUM OF A MODULE [PDF]

open access: yesJournal of Algebraic Systems, 2020
‎‎Let $R$ be a commutative ring with identity and let $M$ be an $R$-module‎. ‎We define the primary spectrum of $M$‎, ‎denoted by $\mathcal{PS}(M)$‎, ‎to be the set of all primary submodules $Q$ of $M$ such that $(\operatorname{rad}Q:M)=\sqrt{(Q:M ...

Topology via spectral projectors with staggered fermions

open access: yesJournal of High Energy Physics, 2019
The spectral projectors method is a way to obtain a theoretically well posed definition of the topological susceptibility on the lattice. Up to now this method has been defined and applied only to Wilson fermions.

Network topology identification from spectral templates [PDF]

open access: yes2016 IEEE Statistical Signal Processing Workshop (SSP), 2016
Network topology inference is a cornerstone problem in statistical analyses of complex systems. In this context, the fresh look advocated here permeates benefits from convex optimization and graph signal processing, to identify the so-termed graph shift operator (encoding the network topology) given only the eigenvectors of the shift.

Throughput Enhancement of Dynamic Full-Duplex Cellular System by Distributing Base Station Reception Function

open access: yesIEEE Open Journal of Vehicular Technology, 2023
In-band full-duplex (IBFD) is a promising technology for improving spectral efficiency beyond 5G and 6G. The dynamic duplex cellular (DDC) system has been proposed as a method for the phased introduction of IBFD into cellular systems while maintaining ...

Spectral Flow and Global Topology of the Hofstadter Butterfly [PDF]

open access: yesPhysical Review Letters, 2017
We study the relation between the global topology of the Hofstadter butterfly of a multiband insulator and the topological invariants of the underlying Hamiltonian. The global topology of the butterfly, i.e., the displacement of the energy gaps as the magnetic field is varied by one flux quantum, is determined by the spectral flow of energy eigenstates

Spectral sparsification of simplicial complexes for clustering and label propagation

open access: yesJournal of Computational Geometry, 2020
As a generalization of the use of graphs to describe pairwise interactions, simplicial complexes can be used to model higher-order interactions between three or more objects in complex systems.
