SUMMARY:[CMT Seminar] Adrian Kantian/ Gunnar Bollmark - 1D electrons coupled to reservoirs: towards new systems of correlated quantum matter and novel devices
DESCRIPTION:Speaker: Adrian Kantian and Gunnar Bollmark (Uppsala University)\n \nTitle: 1-D electrons coupled to reservoirs: towards new systems of correlated quantum matter and novel devices.\n \nTime:  Wednesday\, 2nd of October\, Fika 10:30-11:00 \, Seminar 11:00-12:00\, \n \nPlace: Nordita South\, room 112:028 .\n\nAbstract:\nCorrelated electrons are at the forefront of condensed matter theory. Interacting quasi-1D electrons have seen vast progress in analytical and numerical theory\, and thus in fundamental understanding and quantitative prediction. Yet\, in the 1D limit fluctuations preclude important technological use\, particularly of superconductors. In contrast\, high-Tc superconductors in 2D/3D are not precluded by fluctuations\, but lack a fundamental theory\, making prediction and engineering of their properties very difficult. In this talk we will present  work in progress on combining the advantages of 1D systems with those of higher-dimensional ones\, by advancing the theory of quasi-1D electrons coupled to an electron bath. We will focus on two aspects in particular:  (1) How to enable a new state of matter\, 1D electrons with true superconducting order\, by using fluctuations from a coherent electronic reservoir. (2) A new approach for the deliberate engineering of superconducting systems with properties computable\, and thus optimisable\, ab-initio\, i.e. from their microscopic properties. The use of hard-core bosons at this first stage allows us to rigorously validate our approach\, which yields insight into the physics of dimensional crossover in strongly correlated many-body systems.\n  \n
