Transient thermoelectricity in a vibrating quantum dot in Kondo regime

We investigate the time evolution of the thermopower in a vibrating quantum dot suddenly shifted into the Kondo regime via a gate voltage by adopting the time-dependent non-crossing approximation and linear response Onsager relations. Behaviour of the instantaneous thermopower is studied for a range of temperatures both in zero and strong electron-phonon coupling. We argue that inverse of the saturation value of decay time of thermopower to its steady state value might be an alternative tool in determination of the Kondo temperature and the value of the electron-phonon coupling strength.Comment: 5 pages, 4 figures, to appear in Physics Letters

Intra-Datacenter Network Architectures

This Handbook chapter provides an overview of existing interconnection topologies and architectures for large-scale cloud computing systems. We discuss (a) tree-based solutions (also referred to as indirect topologies in this chapter), largely adopted in most of today’s data center systems, as well as (b) directly connected topologies, such as full mesh (all-to-all), fattened butterfy, and HyperX. This chapter also touches upon some emerging interconnect solutions enabled by recent advances in photonic integrated technologies and switches, while more details about these aspects can be found in the Handbook Chaps. 21, 24, and 25
