Effective Hardcore Exclusion Without Exclusion: Two-Species Pair Annihilation Revisited
Su-Chan Park, Foster Thompson
Reaction-diffusion systems with two species that mutually annihilate through reactions display a slow decay of the total density which follows an anomalous po…
Spectroscopy of Quantum Phase Slips: Visualizing Complex Real-Time Instantons
Foster Thompson, Daniel K. J. Boneß, Mark Dykman +1
Parametrically driven oscillators can emerge as a basis for the next generation of qubits. Classically, these systems exhibit two stable oscillatory states with opposite phases. Up…
Population Dynamics of Schrödinger Cats
Foster Thompson, Alex Kamenev
We demonstrate an exact equivalence between classical population dynamics and Lindbladian evolution admitting a dark state and obeying a set of certain local symmetries. We then in…
Localization of Lindbladian Fermions
Foster Thompson, Yi Huang, Alex Kamenev
We study a Lindbladian generalization of the Anderson model of localization that describes disordered free fermions coupled to a disordered environment. From finite size scaling of…
Field Theory of Many-Body Lindbladian Dynamics
Foster Thompson, Alex Kamenev
We review and further develop the Keldysh functional integral technique for the study of Lindbladian evolution of many-body driven-dissipative quantum systems. A systematic and ped…
Qubit Decoherence and Symmetry Restoration through Real-Time Instantons
Foster Thompson, Alex Kamenev
A parametrically driven quantum oscillator, stabilized by a nonlinear dissipation, exhibits a spontaneous breaking of the parity symmetry. It results in the quantum bi-stability, c…
Griffiths-McCoy Singularities in the Dilute Transverse-Field Ising Model: A Numerical Linked Cluster Expansion Study
Foster Thompson, Rajiv R. P. Singh
We use Numerical Linked Cluster Expansions (NLCE) to study the site diluted transverse-field Ising model on the square-lattice at . NLCE with a self-consistent mean-field on t…
Contact interactions and Kronig-Penney Models in Hermitian and PT-symmetric Quantum Mechanics
Foster Thompson, Katherine Jones-Smith, Harsh Mathur +1
The delta function potential is a simple model of zero-range contact interaction in one dimension. The Kronig-Penney model is a one-dimensional periodic array of delta functions th…
