Towards spintronics via tunneling through asymmetric barriers
Elvira Bilokon, Valeriia Bilokon, Stanislava Litvinova +2
Spin transport typically relies on direct manipulation of the spin degree of freedom via magnetic fields, spin-orbit coupling, or engineered spin-dependent potentials. We show theo…
All You Need is Amplifier: Spectral Imposters Without Pulse Shaping
Valeriia Bilokon, Elvira Bilokon, Denys I. Bondar
Quantum tracking control encodes the desired dynamics into a tailored driving field; here, we let the system find its own way there. We propose a real-time feedback control framewo…
Observables in Motion: A guide to simulating classical and quantum dynamics
Denys I. Bondar, Gerard McCaul, Andrii Sotnikov
We present a pedagogical work-in-progress. This textbook aims to introduce Hilbert space representations for quantum and classical dynamics, outlining the mathematical foundations,…
Dispersion Relations in Two- and Three-Dimensional Quantum Systems
Valeriia Bilokon, Elvira Bilokon, Illya Lukin +2
Extracting momentum-resolved excitation spectra in strongly correlated quantum systems remains a major challenge, especially beyond one spatial dimension. We present an efficient t…
Bose-Einstein condensate sub-wavelength confinement via superoscillations
Dusty R. Lindberg, Gerard McCaul, Peisong Peng +3
Optical lattices are essential tools in ultra-cold atomic physics. Here we demonstrate theoretically that sub-wavelength confinement can be achieved in these lattices through super…
Tuning the terahertz response of liquids by creating polar many-body excitations
Gerard McCaul, Matthias Runge, Michael Woerner +3
A surprising result from the theory of quantum control is the degree to which the properties of a physical system can be manipulated. Both atomic and many-body solid state models a…
