Query: Dynamical Time-Reversal Symmetry Breaking and Photo-Induced Chiral Spin
  Liquids in Frustrated Mott Insulators   The search for quantum spin liquids in frustrated quantum magnets recently
has enjoyed a surge of interest, with various candidate materials under intense
scrutiny. However, an experimental confirmation of a gapped topological spin
liquid remains an open question. Here, we show that circularly-polarized light
can provide a novel knob to drive frustrated Mott insulators into a chiral spin
liquid (CSL), realizing an elusive quantum spin liquid with topological order.
We find that the dynamics of a driven Kagome Mott insulator is well-captured by
an effective Floquet spin model, with heating strongly suppressed, inducing a
scalar spin chirality $S_i \cdot (S_j \times S_k)$ term which dynamically
breaks time-reversal while preserving SU(2) spin symmetry. We fingerprint the
transient phase diagram and find a stable photo-induced CSL near the
equilibrium state. The results presented suggest employing dynamical symmetry
breaking to engineer quantum spin liquids and access elusive phase transitions
that are not readily accessible in equilibrium.
