Splitting the local Hilbert space: MPS-based approach to large local dimensions
Naushad Ahmad Kamar, Mohammad Maghrebi
A large, or even infinite, local Hilbert space dimension poses a significant computational challenge for simulating quantum systems. In this work, we present a matrix product state…
Spin-boson model under dephasing: Markovian vs Non-Markovian dynamics
Naushad Ahmad Kamar, Daniel A. Paz, Mohammad F. Maghrebi
The spin-boson model, describing a two-level system strongly coupled to a bosonic bath, is extensively studied as a paradigmatic dissipative quantum system, exhibiting rich dynamic…
Continuous Symmetry Breaking in a Trapped-Ion Spin Chain
Lei Feng, Or Katz, Casey Haack +5
One-dimensional systems exhibiting a continuous symmetry can host quantum phases of matter with true long-range order only in the presence of sufficiently long-range interactions.…
Singularities in nearly-uniform 1D condensates due to quantum diffusion
C. L. Baldwin, P. Bienias, A. V. Gorshkov +2
Dissipative systems can often exhibit wavelength-dependent loss rates. One prominent example is Rydberg polaritons formed by electromagnetically-induced transparency, which have lo…
Critical Theory for the Breakdown of Photon Blockade
Jonathan B. Curtis, Igor Boettcher, Jeremy T. Young +4
Photon blockade is the result of the interplay between the quantized nature of light and strong optical nonlinearities, whereby strong photon-photon repulsion prevents a quantum op…
A solvable family of driven-dissipative many-body systems
Michael Foss-Feig, Jeremy T. Young, Victor V. Albert +2
Exactly solvable models have played an important role in establishing the sophisticated modern understanding of equilibrium many-body physics. And conversely, the relative scarcity…
