Many-body quantum chaos and time reversal symmetry
Weijun Wu, Saumya Shivam, Amos Chan
We investigate universal signatures of quantum chaos in the presence of time reversal symmetry (TRS) in generic many body quantum chaotic systems (gMBQCs). We study three classes o…
Many-body quantum chaos and emergence of Ginibre ensemble
Saumya Shivam, Andrea De Luca, David A. Huse +1
We show that non-Hermitian Ginibre random matrix behaviors emerge in spatially-extended many-body quantum chaotic systems in the space direction, just as Hermitian random matrix be…
Many-Body Quantum Chaos and Space-time Translational Invariance
Amos Chan, Saumya Shivam, David A. Huse +1
We study the consequences of having translational invariance in space and in time in many-body quantum chaotic systems. We consider an ensemble of random quantum circuits, composed…
Recursive contact tracing in Reed-Frost epidemic models
Saumya Shivam, Vir B. Bulchandani, S. L. Sondhi
We introduce a Reed-Frost epidemic model with recursive contact tracing and asymptomatic transmission. This generalizes the branching-process model introduced by the authors in a p…
Distinct Critical Behaviors from the Same State in Quantum Spin and Population Dynamics Perspectives
C. L. Baldwin, S. Shivam, S. L. Sondhi +1
There is a deep connection between the ground states of transverse-field spin systems and the late-time distributions of evolving viral populations -- within simple models, both ar…
Digital Herd Immunity and COVID-19
Vir B. Bulchandani, Saumya Shivam, Sanjay Moudgalya +1
A population can be immune to epidemics even if not all of its individual members are immune to the disease, so long as sufficiently many are immune - this is the traditional notio…
Studying viral populations with tools from quantum spin chains
Saumya Shivam, Christopher L. Baldwin, John Barton +2
We study Eigen's model of quasi-species, characterized by sequences that replicate with a specified fitness and mutate independently at single sites. The evolution of the populatio…
