Low-energy excitations in addition to regualr phonons are systemically detected in the low-temperature specific heat Cp of quasi-1D systems with a charge density wave. A characteristic manifestation of these ex
First, the pump light energy is focused onto nanoscale hotspots to generate a much larger photocarrier density than graphene devices without metasurfaces. Secondly, the device response at the probe wavelength is highly sensitive to the graphene optical properties in the hotspots and thus results in ...
Although photoexcitation has been employed to unlock the low-temperature equilibrium regimes of thermal catalysis, mechanism underlining potential interplay between electron excitations and surface chemical processes remains elusive. Here, we report an a
We denote the ground state as |0 , and the low energy excited states are constructed by acting on it with a primary operator, obtaining the following set of states: |Vα,α¯ , |J , |J¯ , |J J¯ . We denote the RDMs of A in these states, respectively, as ρα,α¯,...
