Probing non-equilibrium dissipative phase transitions with trapped-ion quantum simulators
Casey Haack, Naushad Ahmad Kamar, Daniel Paz +2
Open quantum many-body systems with controllable dissipation can exhibit novel features in their dynamics and steady states. A paradigmatic example is the dissipative transverse fi…
Mobile Impurity in a Two-Leg Bosonic Ladder
Naushad Ahmad Kamar, Adrian Kantian, Thierry Giamarchi
We study the dynamics of a mobile impurity in a two-leg bosonic ladder. The impurity moves both along and across the legs and interacts with a bath of interacting bosonic particles…
Hybrid Quantum-Classical Stochastic Approach to Spin-Boson Models
Naushad A. Kamar, Mohammad Maghrebi
Interacting spin-boson models encompass a large class of physical systems, spanning models with a single spin interacting with a bosonic bath -- a paradigm of quantum impurity prob…
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…
