Nonlocal Magic Spreading in Many-body Quantum Dynamics: From Chaotic Evolution to Quasi-particle Picture in Integrable Models
Sreemayee Aditya, Piotr Sierant, Xhek Turkeshi
Entanglement and magic are resources that reveal complementary aspects of quantum many-body systems. Their interplay is captured by nonlocal magic, the magic that survives arbitrar…
Equivalence of quantum resources under ergodic dynamics
Sreemayee Aditya, Xhek Turkeshi, Piotr Sierant
Quantum resource theories characterize distinct forms of nonclassicality in many-body quantum states, raising the question of whether these resources evolve independently under gen…
Higher-order Symmetric Quantum Mpemba Effect in Fragmented Systems
Sreemayee Aditya, Sara Murciano, Xhek Turkeshi
A quantum system can restore a broken symmetry faster the more strongly it initially breaks it, an anomaly known as the quantum Mpemba effect. Whether this effect survives once con…
Coherence dynamics in quantum many-body systems with conservation laws
Sreemayee Aditya, Emanuele Tirrito, Piotr Sierant +1
We study how conservation laws shape the spreading of quantum coherence in many-body dynamics. Focusing on -symmetric random circuits, charge-and-dipole conserving circuits,…
Assembling Extensive Quantum Fisher Information in Stabilizer Systems
Arnau Lira-Solanilla, Sreemayee Aditya, Xhek Turkeshi +1
We introduce a systematic framework to construct nonlocal observables with extensive quantum Fisher information (QFI) density in stabilizer codes. The construction maps stabilizer…
Growth and spreading of quantum resources under random circuit dynamics
Sreemayee Aditya, Xhek Turkeshi, Piotr Sierant
Quantum many-body dynamics generate nonclassical correlations naturally described by quantum resource theories. Quantum magic resources (or nonstabilizerness) capture deviation fro…
Mpemba Effects in Quantum Complexity
Sreemayee Aditya, Alessandro Summer, Piotr Sierant +1
The Mpemba effect is the phenomenon whereby systems farther from equilibrium may relax faster. In this work, we show that this counterintuitive behavior appears in the very measure…
Diagnostics of Hilbert space fragmentation, freezing transition, and its effects in the family of quantum East models involving varying range of constraints
Sreemayee Aditya
This paper explores the effect of strong-to-weak fragmentation transition, namely freezing transition, and its rich characteristics in a family of one-dimensional spinless fermioni…
Aspects of Hilbert space fragmentation in the quantum East model: fragmentation, subspace-restricted quantum scars, and effects of density-density interactions
Maitri Ganguli, Sreemayee Aditya, Diptiman Sen
We investigate a one-dimensional correlated-hopping model of spinless fermions with an East constraint. We first analytically unravel the complete fragmentation structure of this m…
Subspace restricted thermalization in a correlated-hopping model with strong Hilbert space fragmentation characterized by irreducible strings
Sreemayee Aditya, Deepak Dhar, Diptiman Sen
We introduce a one-dimensional correlated-hopping model of spinless fermions in which a particle can hop between two neighboring sites only if the sites to the left and right of th…
Family-Vicsek dynamical scaling and Kardar-Parisi-Zhang-like superdiffusive growth of surface roughness in a driven one-dimensional quasiperiodic model
Sreemayee Aditya, Nilanjan Roy
The investigation of the dynamical universality classes of quantum systems is an important, and rather less explored, aspect of non-equilibrium physics. In this work, considering t…
Dynamical localization and slow thermalization in a class of disorder-free periodically driven one-dimensional interacting systems
Sreemayee Aditya, Diptiman Sen
We study if the interplay between dynamical localization and interactions in periodically driven quantum systems can give rise to anomalous thermalization behavior. Specifically, w…
Periodically driven model with quasiperiodic potential and staggered hopping amplitudes: engineering of mobility gaps and multifractal states
Sreemayee Aditya, K. Sengupta, Diptiman Sen
We study if periodic driving of a model with a quasiperiodic potential can generate interesting Floquet phases which have no counterparts in the static model. Specifically, we cons…
Dynamical relaxation of correlators in periodically driven integrable quantum systems
Sreemayee Aditya, Sutapa Samanta, Arnab Sen +2
We show that the correlation functions of a class of periodically driven integrable closed quantum systems approach their steady state value as , where is the num…
Bosonization study of a generalized statistics model with four Fermi points
Sreemayee Aditya, Diptiman Sen
We study a one-dimensional lattice model of fractional statistics in which particles have next-nearest-neighbor hopping between sites which depends on the occupation number at the…
Octahedral tilting induced isospin reorientation transition in iridate heterostructures
Shubhajyoti Mohapatra, Sreemayee Aditya, Rohit Mukherjee +1
Iridate heterostructures are gaining interest as their magnetic properties are much more sensitive to structural distortion compared to pure spin systems due to spin-orbital entang…
