Solution of inverse problem for Gross-Pitaevskii equation with artificial neural networks
Stepan P. Pokatov, Tatiana Yu. Ivanova, Denis A. Ivanov
We propose an Artificial Neural Network (ANN) design to solve the inverse problem for a 1D Gross-Pitaevskii equation (GPE). More precise, the ANN takes the squared modulus of the s…
Dynamical Control of Interlayer Excitons and Trions in WSe/MoWSe Heterobilayer via Tunable Near-Field Cavity
Yeonjeong Koo, Hyeongwoo Lee, Tatiana Ivanova +5
Emerging photo-induced excitonic processes in transition metal dichalcogenide (TMD) heterobilayers, e.g., coupling, dephasing, and energy transfer of intra- and inter-layer exciton…
Tuning the universality class of phase transitions by feedback: Open quantum systems beyond dissipation
D. A. Ivanov, T. Yu. Ivanova, S. F. Caballero-Benitez +1
We shift the paradigm of feedback control from the control of quantum states to the control of phase transitions in quantum systems. We show that feedback allows tuning the univers…
Valley polarization of trions in monolayer MoSe interfaced with bismuth iron garnet
V. Kravtsov, T. Ivanova, A. N. Abramov +8
Interfacing atomically thin van der Waals semiconductors with magnetic substrates enables additional control on their intrinsic valley degree of freedom and provides a promising pl…
Spin-valley dynamics in alloy-based transition metal dichalcogenide heterobilayers
V. Kravtsov, A. D. Liubomirov, R. V. Cherbunin +11
Van der Waals heterobilayers based on 2D transition metal dichalcogenides have been recently shown to support robust and long-lived valley polarization for potential valleytronic a…
Cavityless self-organization of ultracold atoms due to the feedback-induced phase transition
Denis A. Ivanov, Tatiana Yu. Ivanova, Santiago F. Caballero-Benitez +1
Feedback is a general idea of modifying system behaviour depending on the measurement outcomes. It spreads from natural sciences, engineering, and artificial intelligence to contem…
Nonlinear polaritons in monolayer semiconductor coupled to optical bound states in the continuum
V. Kravtsov, E. Khestanova, F. A. Benimetskiy +16
Optical bound states in the continuum (BICs) provide a way to engineer very narrow resonances in photonic crystals. The extended interaction time in such systems is particularly pr…
Feedback-Induced Quantum Phase Transitions Using Weak Measurements
D. A. Ivanov, T. Yu. Ivanova, S. F. Caballero-Benitez +1
We show that applying feedback and weak measurements to a quantum system induces phase transitions beyond the dissipative ones. Feedback enables controlling essentially quantum pro…
Incoherent quantum feedback control of collective light scattering by Bose-Einstein condensates
Denis A. Ivanov, Tatiana Yu. Ivanova, Igor B. Mekhov
It is well known that in the presence of a ring cavity the light scattering from a uniform atomic ensemble can become unstable resulting in the collective atomic recoil lasing. Thi…
Non-Linear Dynamics of Continuously Measured Bose-Einstein Condensates in One-Dimensional Harmonic Traps
T. Yu. Ivanova, M. S. Samoylova, D. A. Ivanov
Continuous center-of-mass position measurements performed on an interacting harmonically trapped Bose-gas are considered. Using both semi-analytical mean-field approach and complet…
