Topology in the SSH Model
The Su–Schrieffer–Heeger (SSH) model is the minimal one-dimensional lattice model in which band topology can be formulated exactly. Its structure is a bipartite chain with two sites per unit cell and alternating hopping amplitudes $t1$ and…
Nietzsche on Nihilism
For Nietzsche, nihilism is the historical condition in which the highest values lose their authority. Its origin lies within the structure of Western metaphysics itself. Christianity, Platonism, and later moral rationalism all taught human…
Detailed Balance in Single-Junction Photovoltaics
The Shockley–Queisser limit is the detailed-balance efficiency limit of an ideal single-junction photovoltaic absorber. Its derivation requires only a few assumptions: photons with energy above the bandgap are absorbed, each absorbed photon…
