Suppression of tunneling two-level systems in ultrastable glasses of indomethacin
Tomás Pérez-Castañeda, Cristian Rodríguez-Tinoco, Javier Rodríguez-Viejo +1
Glasses and other non-crystalline solids exhibit thermal and acoustic properties at low temperatures anomalously different from those found in crystalline solids, and with a remark…
Two-Level Systems and Boson Peak Remain Stable in 110-Million-Year-Old Amber Glass
Tomás Pérez-Castañeda, Rafael J. Jiménez-Riobóo, Miguel A. Ramos
The two most prominent and ubiquitous features of glasses at low temperatures, namely the presence of tunneling two-level systems and the so-called boson peak in the reduced vibrat…
Low-temperature specific heat of graphite and CeSb2: Validation of a quasi-adiabatic continuous method
T. Pérez-Castañeda, J. Azpeitia, J. Hanko +3
We present the application of a fast quasi-adiabatic continuous method to the measurement of specific heat at 4He temperatures, which can be used for the study of a wide range of m…
