  Advanced scanning probe microscopy of low-dimensional molecular systems revealing exotic quantum states

  Low dimensional materials offer very interesting material and physical properties due to reduced dimensionality. At present, 2D materials are the focus of attention. However, 1D systems often show far more exotic features, such as Tomanaga-Luttinger liquid, Peierls distortion, etc.. In this talk, we will present p-conjugated molecular chains of distinct topological classes formed on metallic surfaces by on-surface synthesis, which physical properties were investigated by low temperature UHV scanning probe microscopy supported by theoretical analysis.
  First, we will introduce a novel strategy to synthesize [1] a new class of intrinsically quasi-metallic one-dimensional (1D) p-conjugated polymers featuring topologically non-trivial quantum states. Furthermore, we unveiled the fundamental relation between quantum topology, p-conjugation and metallicity of polymers [2]. Thus, we will make a connection between two distinct worlds of topological band theory (condensed matter physics) and p-conjugation polymer science (chemistry). We believe this may stimulate new ways of thinking towards a design of novel organic quantum materials.
  In second part, we will demonstrate unusual mechanical and electronic properties of hydrogen bonded chains formed on a metallic surface driven by quantum nuclear effects within the chain [3].
