Bloch oscillations of bosonic lattice polarons
Fabian Grusdt, Aditya Shashi, Dmitry Abanin +1
We consider a single impurity atom confined to an optical lattice and immersed in a homogeneous Bose-Einstein condensate (BEC). Interaction of the impurity with the phonon modes of…
Frustration and Multicriticality in the Antiferromagnetic Spin-1 Chain
J. H. Pixley, Aditya Shashi, Andriy H. Nevidomskyy
We study the spin Heisenberg chain, with nearest neighbor, next nearest neighbor () and biquadratic () interactions using a combination of the density matrix renormaliz…
Radio frequency spectroscopy of polarons in ultracold Bose gases
Aditya Shashi, Fabian Grusdt, Dmitry A. Abanin +1
Recent experimental advances enabled the realization of mobile impurities immersed in a Bose-Einstein condensate (BEC) of ultracold atoms. Here we consider impurities with two or m…
Interaction quenches in the 1D Bose gas
Marton Kormos, Aditya Shashi, Yang-Zhi Chou +2
The non-equilibrium dynamics of integrable systems are special: there is substantial evidence that after a quantum quench they do not thermalize but their asymptotic steady state c…
Time dependent impurity in ultracold fermions: orthogonality catastrophe and beyond
Michael Knap, Aditya Shashi, Yusuke Nishida +3
Recent experimental realization of strongly imbalanced mixtures of ultracold atoms opens new possibilities for studying impurity dynamics in a controlled setting. We discuss how th…
Interaction quenches in the Lieb-Liniger model
Marton Kormos, Aditya Shashi, Yang-Zhi Chou +1
We obtain exact results on interaction quenches in the 1D Bose gas described by the integrable Lieb-Liniger model. We show that in the long time limit integrability leads to signif…
