Conductance zeros in complex molecules and lattices from the interference set method
M. Nita, M. Tolea, D. C. Marinescu
Destructive quantum interference (DQI) and its effects on electron transport is studied in chemical molecules and finite physical lattices that can be described by a discrete Hamil…
Robust conductance zeroes in graphene quantum dots and other bipartite systems
M. Nita, M. Tolea, D. C. Marinescu
Within the Landauer transport formalism we demonstrate that conductance zeroes are possible in bipartite systems at half-filling when leads are contacted to different sublattice si…
Simulation of Quantum Many-Body Systems on Amazon Cloud
Justin A. Reyes, Eduardo R. Mucciolo, Dan Marinescu
Quantum many-body systems (QMBs) are some of the most challenging physical systems to simulate numerically. Methods involving approximations for tensor network (TN) contractions ha…
Hund and anti-Hund rules in circular molecules
M. Nita, M. Tolea, D. C. Marinescu +1
We study the validity of Hund's first rule for the spin multiplicity in circular molecules - made of real or artificial atoms such as quantum dots - by considering a perturbative a…
Distributed Hierarchical Control versus an Economic Model for Cloud Resource Management
Dan C. Marinescu, Ashkan Paya, John P. Morrison +1
We investigate a hierarchically organized cloud infrastructure and compare distributed hierarchical control based on resource monitoring with market mechanisms for resource managem…
Coalition Formation and Combinatorial Auctions; Applications to Self-organization and Self-management in Utility Computing
Dan C. Marinescu, Ashkan Paya, John P. Morrison
In this paper we propose a two-stage protocol for resource management in a hierarchically organized cloud. The first stage exploits spatial locality for the formation of coalitions…
