On the records
Andrew Berdahl, Uttam Bhat, Vanessa Ferdinand +12
World record setting has long attracted public interest and scientific investigation. Extremal records summarize the limits of the space explored by a process, and the historical p…
Densification and Structural Transitions in Networks that Grow by Node Copying
U. Bhat, P. L. Krapivsky, R. Lambiotte +1
We introduce a growing network model---the copying model---in which a new node attaches to a randomly selected target node and, in addition, independently to each of the neighbors…
Structural Transitions in Dense Networks
R. Lambiotte, P. L. Krapivsky, U. Bhat +1
We introduce an evolving network model in which a new node attaches to a randomly selected target node and also to each of its neighbors with probability . The resulting network…
Exotic phase transitions of k-cores in clustered networks
Uttam Bhat, Munik Shrestha, Laurent Hébert-Dufresne
The giant -core --- maximal connected subgraph of a network where each node has at least neighbors --- is important in the study of phase transitions and in applications of…
Stochastic Search with Poisson and Deterministic Resetting
Uttam Bhat, Caterina De Bacco, S. Redner
We investigate a stochastic search process in one, two, and three dimensions in which diffusing searchers that all start at seek a target at the origin. Each of the searc…
Exclusion Processes with Avalanches
Uttam Bhat, P. L. Krapivsky
In an exclusion process with avalanches, when a particle hops to a neighboring empty site which is adjacent to an island the particle on the other end of the island immediately hop…
