We have developed a far-infrared-absorption-measurement method using an optically pumped far-infrared laser. The temperature dependence of the light absorption by high-T, superconductors has been investigated for the photon energy between 7.6 and 17.6 meV in the temperature region between 12 and 160 K. A well-defined transition temperature was obtained from the absorption measurement. With decreasing temperature, the absorption decreased, but did not reach zero even at su%ciently low temperatures.

It has recently been shown that the statistical mechanics of crystal melting maps to A-model topological string amplitudes on non-compact Calabi-Yau spaces. In this note we establish a one to one correspondence between two and three dimensional crystal melting configurations and certain BPS black holes given by branes wrapping collapsed cycles on the orbifolds C 2 /Z n and C 3 /Z n × Z n in the large n limit. The ranks of gauge groups in the associated gauged quiver quantum mechanics determine the profiles of crystal melting configurations and the process of melting maps to flop transitions which leave the background Calabi-Yau invariant. We explain the connection between these two realizations of crystal melting and speculate on the underlying physical meaning.
