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…
Observable signatures of exceptional points from left-right eigenstate distinction
Leela Ganesh Chandra Lakkaraju, Soumik Bandyopadhyay, Sudipto Singha Roy +1
Non-Hermitian quantum systems exhibit qualitatively distinct physical behavior compared to Hermitian systems, a prime example being spectral singularities known as exceptional poin…
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…
The hyperlink representation of entanglement and the inclusion-exclusion principle
Silvia N. Santalla, Sudipto Singha Roy, Germán Sierra +1
The entanglement entropy (EE) of any bipartition of a pure state can be approximately expressed as a sum of entanglement links (ELs). In this work, we introduce their exact extensi…
