Onset of many-body quantum chaos due to breaking integrability
Vir B. Bulchandani, David A. Huse, Sarang Gopalakrishnan
Integrable quantum systems of finite size are generically robust against weak enough integrability-breaking perturbations, but become quantum chaotic and thermalizing if the integr…
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…
Hydrodynamics of quantum spin liquids
Vir B. Bulchandani, Benjamin Hsu, Christopher P. Herzog +1
Quantum spin liquids are topological states of matter that arise in frustrated quantum magnets at low temperatures. At low energies, such states exhibit emergent gauge fields and f…
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…
