Precursors of the insulating state in the square lattice Hubbard model
Erik G. C. P. van Loon, Hartmut Hafermann, Mikhail Katsnelson
We study the two-dimensional square lattice Hubbard model for small to moderate interaction strengths by means of the ladder dual fermion approach. The non-local…
Adaptive Robust Traffic Engineering in Software Defined Networks
Davide Sanvito, Ilario Filippini, Antonio Capone +2
One of the key advantages of Software-Defined Networks (SDN) is the opportunity to integrate traffic engineering modules able to optimize network configuration according to traffic…
Nonlinearity-tolerant 8D modulation formats by set-partitioning PDM-QPSK
D. F. Bendimerad, H. Hafermann, H. Zhang
We present two new nonlinearity tolerant modulation formats at spectral efficiencies lower than 4bits/4D-symbol, obtained using a simplified bit-to-symbol mapping approach to set-p…
An Approximate Shapley-Folkman Theorem
Thomas Kerdreux, Igor Colin, Alexandre d'Aspremont
The Shapley-Folkman theorem shows that Minkowski averages of uniformly bounded sets tend to be convex when the number of terms in the sum becomes much larger than the ambient dimen…
Echo State Transfer Learning for Data Correlation Aware Resource Allocation in Wireless Virtual Reality
Mingzhe Chen, Walid Saad, Changchuan Yin +1
In this paper, the problem of data correlation-aware resource management is studied for a network of wireless virtual reality (VR) users communicating over cloud-based small cell n…
Energy-Delay Efficient Power Control in Wireless Networks
Alessio Zappone, Luca Sanguinetti, Merouane Debbah
This work aims at developing a power control framework to jointly optimize energy efficiency (measured in bit/Joule) and delay in wireless networks. A multi-objective approach is t…
