Measurement-Selective Dynamical Symmetry Breaking
Polina Kofman, Elvira Bilokon, Valeriia Bilokon +1
Continuous measurement is commonly associated with decoherence and the loss of symmetry. Here, we show that weak continuous measurements can instead act selectively: depending on t…
Nonlinear Response via Sublinear Optics
Mykhaylo Khoma, Valeriia Bilokon, Elvira Bilokon +1
Sublinear optical response, in which the emitted field scales as a fractional power of the driving field, lies beyond the conventional perturbative hierarchy of nonlinear optics. H…
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…
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,…
