Quantum Quench Across a Zero Temperature Holographic Superfluid Transition
Pallab Basu, Diptarka Das, Sumit R. Das +1
We study quantum quench in a holographic model of a zero temperature insulator-superfluid transition. The model is a modification of that of arXiv:0911.0962 and involves a self-cou…
Bi-local Construction of Sp(2N)/dS Higher Spin Correspondence
Diptarka Das, Sumit R. Das, Antal Jevicki +1
We derive a collective field theory of the singlet sector of the Sp(2N) sigma model. Interestingly the hamiltonian for the bilocal collective field is the same as that of the O(N)…
Chaos around Holographic Regge Trajectories
Pallab Basu, Diptarka Das, Archisman Ghosh +1
Using methods of Hamiltonian dynamical systems, we show analytically that a dynamical system connected to the classical spinning string solution holographically dual to the princip…
