Exploring kinetically induced bound states in triangular lattices with ultracold atoms: Spectroscopic approach

“…Besides, in this work we have only focused on the single polaron spectroscopy. However, analysis of interactions between polarons is also an interesting research avenue [83,[103][104][105][106][107] and we plan to address this question in future publications.…”

“…On the theoretical side, most efforts have been focused on understanding magnetic polarons in square lattices, with similar results expected to hold for all bipartite lattices [52,. However several theoretical studies considered non-bipartite triangular lattices and pointed out intriguing effects of frustration on magnetic polarons [1,[82][83][84][85]. Specifically, antiferromagnetic polarons appear when a Mott insulator in a triangular lattice is doped with a low density of holes.…”

Collective excitations of a Bose–Einstein condensate of hard-core bosons and their mediated interactions: from two-body bound states to mediated superfluidity

“…Quantum microscopy delivered a powerful tool to explore phases of matter in optical lattices with site-by-site imaging [32], motivating the study of Bose lattice polarons [33], their mediated interactions [34] and strongly correlated physics with lattice Fermi polarons [35][36][37][38][39][40][41][42][43]. The increasing interest on strongly correlated quantum gases in optical lattices is therefore motivated by a parallel development of the abilities to measure such phases with unprecedented control.…”
