Many-body spin echo

T Engl, JD Urbina, K Richter, P Schlagheck - Physical Review A, 2018 - APS
We show that quantum coherence produces an observable many-body signature in the
dynamics of few-fermion Hubbard systems (describing cold atoms in optical lattices, coupled …

Analysis of the buildup of spatiotemporal correlations and their bounds outside of the light cone

N Abeling, L Cevolani, S Kehrein - SciPost Physics, 2018 - scipost.org
In non-relativistic quantum theories the Lieb-Robinson bound defines an effective light cone
with exponentially small tails outside of it. In this work we use it to derive a bound for the time …

Semiclassical theory of few-and many-body quantum systems with short-range interactions

Q Hummel - 2018 - epub.uni-regensburg.de
The thesis addresses the fundamental interplay between indistinguishability and
interactions in few-and many-body quantum systems, treated in two separate approaches …

Heat Transport and Majorana Fermions in a Superconducting Dot‐Wire System: An Exact Solution

O Bohórquez, AMS Macêdo - Advances in Mathematical …, 2018 - Wiley Online Library
We obtain exact expressions for the first three moments of the heat conductance of a
quantum chain that crosses over from a superconducting quantum dot to a superconducting …

Direct extraction of electron parameters from magnetoconductance analysis in mesoscopic ring array structures

A Sawada, S Faniel, S Mineshige, S Kawabata, K Saito… - Physical Review B, 2018 - APS
We report an approach for examining electron properties using information about the shape
and size of a nanostructure as a measurement reference. This approach quantifies the spin …
