Emergent multifractality in power-law decaying eigenstates
Adway Kumar Das, Anandamohan Ghosh, Ivan M. Khaymovich
Eigenstate multifractality is of significant interest with potential applications in various fields of quantum physics. Most of the previous studies concentrated on fine-tuned quan…
Re-entrant localization induced by short-range hopping in the fractal Rosenzweig-Porter Model
Roopayan Ghosh, Madhumita Sarkar, Ivan M. Khaymovich
Typically, metallic systems localized under strong disorder exhibit a transition to \imk{delocalization} %finite conduction as kinetic terms increase. In this work, we reveal the o…
Refined cyclic renormalization group in Russian Doll model
Vedant Motamarri, Ivan M. Khaymovich, Alexander Gorsky
Focusing on Bethe-ansatz integrable models, robust to both time-reversal symmetry breaking and disorder, we consider the Russian Doll Model (RDM) for finite system sizes and energy…
Robust non-ergodicity of ground state in the ensemble
Adway Kumar Das, Anandamohan Ghosh, Ivan M. Khaymovich
In various chaotic quantum many-body systems, the ground states show non-trivial athermal behavior despite the bulk states exhibiting thermalization. Such athermal states play a cr…
Stable many-body localization under random continuous measurements in the no-click limit
Giuseppe De Tomasi, Ivan M. Khaymovich
In this work, we investigate the localization properties of a paradigmatic model, coupled to a monitoring environment and possessing a many-body localized (MBL) phase. We focus on…
Anatomy of the eigenstates distribution: a quest for a genuine multifractality
Anton Kutlin, Ivan M. Khaymovich
Motivated by a series of recent works, an interest in multifractal phases has risen as they are believed to be present in the Many-Body Localized (MBL) phase and are of high demand…
