Quantifying non-Hermiticity using single- and many-particle quantum properties
Soumik Bandyopadhyay, Philipp Hauke, Sudipto Singha Roy
The non-Hermitian paradigm of quantum systems displays salient features drastically different from Hermitian counterparts. In this work, we focus on one such aspect, the difference…
Unveiling Eigenstate Thermalization for Non-Hermitian systems
Sudipto Singha Roy, Soumik Bandyopadhyay, Ricardo Costa de Almeida +1
The eigenstate thermalization hypothesis (ETH) has been highly influential in explaining thermodynamic behavior of closed quantum systems. As of yet, it is unclear whether and how…
Growth of genuine multipartite entanglement in random unitary circuits
Anindita Bera, Sudipto Singha Roy
We study the growth of genuine multipartite entanglement in random quantum circuit models, which include random unitary circuit models and the random Clifford circuit. We find that…
Entanglement as geometry and flow
Sudipto Singha Roy, Silvia N. Santalla, Javier Rodríguez-Laguna +1
We explore the connection between the area law for entanglement and geometry by representing the entanglement entropies corresponding to all bipartitions of an -party pure…
Benford analysis of quantum critical phenomena: First digit provides high finite-size scaling exponent while first two and further are not much better
Anindita Bera, Utkarsh Mishra, Sudipto Singha Roy +3
Benford's law is an empirical edict stating that the lower digits appear more often than higher ones as the first few significant digits in statistics of natural phenomena and math…
