Curvature-induced bound states in quantum wires
Tim Bergmann, Benjamin Schwager, Jamal Berakdar
A classical particle under spatial constraints is strictly confined to live on a specific space manifold or path, but this assumption is incompatible with the zero-point fluctuatio…
Quantum Scattering of Spinless Particles in Riemannian Manifolds
Lars Meschede, Benjamin Schwager, Dominik Schulz +1
Quantum mechanics is sensitive to the geometry of the underlying space. Here, we present a framework for quantum scattering of a non-relativistic particle confined to a two-dimensi…
Machine Learning Universal Bosonic Functionals
Jonathan Schmidt, Matteo Fadel, Carlos L. Benavides-Riveros
The one-body reduced density matrix plays a fundamental role in describing and predicting quantum features of bosonic systems, such as Bose-Einstein condensation. The recently…
Electrons in intense laser fields with local phase, polarization, and skyrmionic textures
Jonas Wätzel, Jamal Berakdar
Laser fields can be shaped on a subwavelength scale as to have a specific distribution in spin angular momentum, orbital structure, or topology. We study how these various features…

Reduced Density Matrix Functional Theory for Bosons
Carlos L. Benavides-Riveros, Jakob Wolff, Miguel A. L. Marques +1
Based on a generalization of Hohenberg-Kohn's theorem, we propose a ground state theory for bosonic quantum systems. Since it involves the one-particle reduced density matrix a…
Implications of pinned occupation numbers for natural orbital expansions. I: Generalizing the concept of active spaces
Christian Schilling, Carlos L. Benavides-Riveros, Alexandre Lopes +2
The concept of active spaces simplifies the description of interacting quantum many-body systems by restricting to a neighbourhood of active orbitals around the Fermi level. The re…
Spin-orbit-coupled quantum memory of a double quantum dot

The concept of quantum memory plays an incisive role in the quantum information theory. As confirmed by several recent rigorous mathematical studies, the quantum memory inmate in t…
Time-resolved buildup of two-slit-type interference from a single atom
Jonas Wätzel, Andrew James Murray, Jamal Berakdar
A photoelectron forced to pass through two atomic energy levels before receding from the residual ion shows interference fringes in its angular distribution as manifestation of a t…
