Determining the Number of Symmetry Sectors in Composite Quantum Spectra
Nisarg Vyas, S. Harshini Tekur, M. S. Santhanam
The spectral fluctuations in complex quantum systems are modeled in terms of spectra from random matrices. Quantitative agreement with random matrices holds only when the quantum s…

Extreme Events of Quantum Walks on Graphs
Nisarg Vyas, M. S. Santhanam
Due to the unitary evolution, quantum walks display different dynamical features from that of classical random walks. In contrast to this expectation, in this work, we show that ex…
