Spiky strings in $\mathrm{\varkappa }$-deformed $AdS$

We study rigidly rotating strings in $\mathrm{\varkappa }$-deformed $AdS$ background. We probe this classically integrable background with `spiky’ strings and analyze the string profiles in the large charge limit systematically. We also discuss the dispersion relation among the conserved charges for these solutions in long string limit.
