Wh ile traditional approaches to topological materials discovery rely on chem istry\, the rise of moiré quantum materials suggests a different strategy : engineering topology by tailoring the physical environment. \n\nIn this talk I will highlight my group’s recent efforts to control scalable topo logical quantum matter using the two most fundamental physical knobs – s pace and time. We constructed a unique testbed to manipulate and probe mat erials at femtosecond time scale and atomic-layer spatial scale [1]. In sp ace\, by epitaxially straining topological superconductors FeTexSe1-x to S rTiO3 substrates\, we suppress the competing antiferromagnetic phase near the FeTe limit and uncover a new tuning mechanism for topological supercon ductivity: electronic correlations [2]. In time\, we show that topological electronic states carry intrinsic layer-dependent vibrational fingerprint s. By “listening” to these frequencies as the states couple to coheren t phonons\, we develop a quantum stethoscope capable of resolving long-sta nding puzzles in magnetic topological insulators\, including the elusive b roken-symmetry energy gap [3]. In combined space-time co-engineering\, I w ill present our latest results integrating photonic crystal cavities with ultrathin topological insulators to realize cavity-driven Floquet engineer ing [4]. This platform represents a new class of physical-environment cont rol experiments\, where the ground states of topological materials are res haped simultaneously in space and time. Together\, these examples illustra te a paradigm in which topological phenomena can be designed and manipulat ed by engineering the physical environment\, and potentially stabilized ne ar ambient conditions – opening pathways toward scalable quantum materia ls and devices.\n\n[1] C.
