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…
Hilbert Space Black Hole Analog: Unidirectional Transport without Driving
Elvira Bilokon, Valeriia Bilokon, Frank GroÃmann +2
Black holes permit matter to cross their event horizon in only one direction. We show that interacting bosons in optical lattices with asymmetric barrier exhibit an analogous pheno…
Predicting Entanglement Entropy from Particle Tunneling of Interacting Fermions Using Kolmogorov-Arnold Networks
Elvira Bilokon, Valeriia Bilokon, Abhijit Sen +3
Entanglement entropy is a fundamental measure of quantum correlations and a key resource underpinning advances in quantum information and many-body physics. We uncover a universal…
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…
