Digital Twin Modeling of Quantum Dynamical Systems: Dissipative Quantum Reservoir Computing
Abhijit Sen, Bikram Keshari Parida, Shital Chauhan +2
Modeling the response of driven many-body quantum systems from input--output data is difficult: the dynamics are nonlinear, history dependent, and expensive to simulate as system s…
Low-rank propagation for tridiagonalizable open quantum systems: near-linear scaling with system size
Roman Ovsiannikov, Kurt Jacobs, Andrii G. Sotnikov +1
The quadratic growth of the density matrix with Hilbert-space dimension D is the central obstacle to simulating large open quantum systems. We introduce a deterministic algorithm t…
Klein tunneling through an asymmetric barrier: Symmetric transmission and directional pair creation
Andre G. Campos, Denys I. Bondar
We prove that the transmission probability for the Klein tunneling through a spatially asymmetric barrier is the same for left and right incidence whenever each asymptotic lead car…
Solvated electrons in polar liquids as epsilon-near-zero materials tunable in the terahertz frequency range
Matthias Runge, Michael Woerner, Denys I. Bondar +1
Electrons in polar liquids give rise to a polaron resonance at a terahertz (THz) frequency ν_0 depending on electron concentration. The impact of this resonance on light propagatio…
Quantum Dynamical Emulation of Imaginary Time Evolution
Jacob M. Leamer, Alicia B. Magann, Denys I. Bondar +1
We introduce a constructive method for mapping non-unitary dynamics to a weighted set of unitary operations. We utilize this construction to derive a new correspondence between rea…
Spectral gaps of two- and three-dimensional many-body quantum systems in the thermodynamic limit
Illya V. Lukin, Andrii G. Sotnikov, Jacob M. Leamer +2
We present an expression for the spectral gap, opening up new possibilities for performing and accelerating spectral calculations of quantum many-body systems. We develop and demon…
