چکیده
Mattia Walschaers,1, 2, ∗ Andreas Buchleitner,1 and Mark Fannes2 1Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, Hermann-Herder-Str. 3, D-79104 Freiburg, Germany 2Instituut voor Theoretische Fysica, KU Leuven, Celestijnenlaan 200D, B-3001 Heverlee, Belgium (Dated: June 10, 2016) Abstract We study particle currents for indistinguishable particles driven far from equilibrium. Our goal is to understand the limits to the particle flow in such systems and how to engineer them to reach these limits. Specifically, we introduce in a many-fermion system a mechanism of symmetry enhancement in the regime where the coupling between system and bath is weak. This mechanism is broadly applicable provided the inter-particle interactions are small with respect to the statistical effects.

Determination of Optimal Allocation and Penetration Level of Distributed Energy Resources Considering Short Circuit Currents
The integration of Distributed Energy Resources (DER) in the distribution network has plenty of advantages if their allocation and Penetration Level (PL) are done appropriately. Hence, the challenge of finding the best allocation and PL of DERs in large distribution networks is an important but intricate problem. This paper proposes a novel methodology to simultaneously determine the optimal lo...
متن کاملQuantum Correlations in Systems of Indistinguishable Particles
We discuss quantum correlations in systems of indistinguishable particles in relation to entanglement in composite quantum systems consisting of well separated subsystems. Our studies are motivated by recent experiments and theoretical investigations on quantum dots and neutral atoms in microtraps as tools for quantum information processing. We present analogies between distinguishable particle...
متن کاملPSO for multi-objective problems: Criteria for leader selection and uniformity distribution
This paper proposes a method to solve multi-objective problems using improved Particle Swarm Optimization. We propose leader particles which guide other particles inside the problem domain. Two techniques are suggested for selection and deletion of such particles to improve the optimal solutions. The first one is based on the mean of the m optimal particles and the second one is based on appoin...
متن کاملTheoretical limit in the magnetization reversal of stoner particles.
Magnetization reversal of uniaxial Stoner particles under the Slonczewski spin-transfer torques of polarized electric currents is investigated. Based on the modified Landau-Lifshitz-Gilbert equation of magnetization dynamics, the theoretical limit of critical currents required to reverse a magnetization with an arbitrary polarized current is obtained. Under a constant polarization degree and co...
متن کاملProtection Scheme of Power Transformer Based on Time–Frequency Analysis and KSIR-SSVM
The aim of this paper is to extend a hybrid protection plan for Power Transformer (PT) based on MRA-KSIR-SSVM. This paper offers a new scheme for protection of power transformers to distinguish internal faults from inrush currents. Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...
