Krylov Complexity and Quantum Many-body Scars in Non-Hermitian Kinetically Constrained Models
Arkaprava Sil, Rudraksh Kaushik, Souvik Kundu +2
Thermalization in closed quantum systems and its breakdown are central to understanding the emergence of statistical behavior in isolated many-body systems. Kinetic constraints can…
Pulse Engineering of Quantum Many-Body Dynamics: Emergent Scar States, Entanglement, and Nonstabilizerness
Prasant Mallik, Arkaprava Sil, Sudipto Singha Roy
Understanding and coherently controlling the properties of interacting quantum many-body systems is a central challenge in non-equilibrium quantum physics. While in the past decade…
Resource generation and dynamical complexities in open random quantum circuits
Paranjoy Chaki, Arkaprava Sil, Priya Ghosh +2
Realistic quantum devices are inherently open and often involve environments with memory. Here, we investigate quantum resource generation in two classes of random circuits, namely…
Quantum Complexity in Rule-Based Constrained Many-Body Models: Scars, Fragmentation, and Chaos
Arkaprava Sil, Sudipto Singha Roy
Kinetic constraints in quantum many-body systems strongly restrict the accessible Hilbert space, giving rise to highly nontrivial dynamical behavior. In recent years, such systems…
