Kibble-Zurek problem: Universality and the scaling limit
- A. Chandran, Amir Erez, S. Gubser, S. Sondhi
- Physics
- 23 February 2012
Near a critical point, the equilibrium relaxation time of a system diverges and any change of control/thermodynamic parameters leads to non-equilibrium behavior. The Kibble-Zurek problem is to…

Signatures of integrability in the dynamics of Rydberg-blockaded chains
- V. Khemani, C. Laumann, A. Chandran
- PhysicsPhysical review B
- 5 July 2018
A recent experiment on a 51-atom Rydberg-blockaded chain observed anomalously long-lived temporal oscillations of local observables after quenching from an antiferromagnetic initial state. This…
Characterization of a qubit Hamiltonian using adaptive measurements in a fixed basis
- Alexandr Sergeevich, A. Chandran, J. Combes, S. Bartlett, H. Wiseman

We investigate schemes for Hamiltonian parameter estimation of a two-level system using repeated measurements in a fixed basis. The simplest (Fourier based) schemes yield an estimate with a…
Extraordinary optical absorption through subwavelength slits.

- PhysicsOptics Letters
- 1 March 2009
It is shown that absorption enhancements of nearly 1000% can be realized at 633 nm for slits in aluminum films filled with silicon, which well exceeds the enhancements seen for extraordinary optical transmission through slits.
Many-body localization beyond eigenstates in all dimensions
- A. Chandran, A. Pal, C. Laumann, A. Scardicchio

Isolated quantum systems with quenched randomness exhibit many-body localization (MBL), wherein they do not reach local thermal equilibrium even when highly excited above their ground states. It is…
Real-space entanglement spectrum of quantum Hall states
- A. Sterdyniak, A. Chandran, N. Regnault, B. Bernevig, Parsa Bonderson
- Physics
- 11 November 2011
We investigate the entanglement spectra arising from sharp real-space partitions of the system for quantum Hall states. These partitions differ from the previously utilized orbital and particle…
Spectral properties of plasmonic resonator antennas.

- PhysicsOptics Express
- 13 October 2008
A Fabry-P erot model was formulated that successfully predicts both the peak position and spectral shape of metallic nano-strip antennas and provides simple design rules for engineering resonant properties of such plasmonic resonator antennas.
Equilibration and coarsening in the quantum O(N) model at infinite N
- A. Chandran, Arun Nanduri, S.S.Gubser, S.L.Sondhi
- Physics
- 8 April 2013
The quantum O(N) model in the infinite $N$ limit is a paradigm for symmetry-breaking. Qualitatively, its phase diagram is an excellent guide to the equilibrium physics for more realistic values of…
Spectral tensor networks for many-body localization
- A. Chandran, J. Carrasquilla, I. H. Kim, D. Abanin, G. Vidal
- Mathematics
- 2 October 2014
Subsystems of strongly disordered, interacting quantum systems can fail to thermalize because of the phenomenon of many-body localization (MBL). In this article, we explore a tensor network…
