Area of Science:

  • Condensed matter physics
  • Quantum chemistry
  • Surface science

Background:

  • Recent experiments investigated chromium trimers on gold surfaces.
  • Understanding strongly correlated electron systems is crucial in condensed matter physics.

Purpose of the Study:

  • To study the strongly correlated state of a chromium (Cr) trimer on gold.
  • To explain the experimental observation of a zero-bias anomaly in Cr trimers.

Main Methods:

  • Combining ab initio calculations with renormalization group methods.
  • Investigating internal orbital fluctuations within the Cr trimer.

Main Results:

  • A huge increase in the Kondo temperature (T(K)) was observed compared to single-ion systems.
  • This enhancement is attributed to internal orbital fluctuations of the trimer.
  • The findings explain the experimental zero-bias anomaly for Cr trimers.

Conclusions:

  • The strongly correlated state of the Cr trimer on gold suggests a new class of non-Fermi-liquid fixed points.
  • This research opens avenues for exploring previously uncharted non-Fermi-liquid phenomena.
