Quasiparticle kinetic theory for Calogero models
Vir B. Bulchandani, Manas Kulkarni, Joel E. Moore +1
We show that the quasiparticle kinetic theory for quantum and classical Calogero models reduces to the free-streaming Boltzmann equation. We reconcile this simple emergent behaviou…
How smooth is quantum complexity?
Vir B. Bulchandani, S. L. Sondhi
The "quantum complexity" of a unitary operator measures the difficulty of its construction from a set of elementary quantum gates. While the notion of quantum complexity was first…
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…
Superdiffusion in spin chains
Vir B. Bulchandani, Sarang Gopalakrishnan, Enej Ilievski
This review summarizes recent advances in our understanding of anomalous transport in spin chains, viewed through the lens of integrability. Numerical advances, based on tensor-net…
Kardar-Parisi-Zhang universality from soft gauge modes
Vir B. Bulchandani
The emergence of superdiffusive spin dynamics in integrable classical and quantum magnets is well established by now, but there is no generally valid theoretical explanation for th…
The GGE averaged currents of the classical Toda chain
Xiangyu Cao, Vir B. Bulchandani, Herbert Spohn
The Toda chain with random initial data is studied. Of particular interest are generalized Gibbs ensembles, their averaged conserved fields, and the averages of the corresponding c…
