Thermal Constraints on the Longevity, Depth, and Vertical Extent of Magmatic Systems
Geochemistry, Geophysics, Geosystems, 2021 Magmatic regions are typically viewed as vertical systems, with magma coming in the bottom and either freezing in the crust to form plutons or erupting to form volcanic rocks.

Thermal Dissipation and Variability in Electrical Breakdown of Carbon Nanotube Devices
, 2010 We study high-field electrical breakdown and heat dissipation from carbon nanotube (CNT) devices on SiO2 substrates. The thermal "footprint" of a CNT caused by van der Waals interactions with the substrate is revealed through molecular dynamics (MD ...

Multi-Variable Thermal Modeling of Power Devices Considering Mutual Coupling
Applied Sciences, 2019 In relation to power converter design, power density is increasing while the form factor is decreasing. This trend generally reduces the rate of the cooling process, which increases the mutual thermal coupling among the surrounding power components. Most

Effect of stress and temperature on the optical properties of silicon nitride membranes at 1550 nm [PDF]
, 2018 Future gravitational-wave detectors operated at cryogenic temperatures are expected to be limited by thermal noise of the highly reflective mirror coatings. Silicon nitride is an interesting material for such coatings as it shows very low mechanical loss,

Matrix Models for Eigenstate Thermalization
Physical Review X, 2023 We develop a class of matrix models which implement and formalize the `eigenstate thermalization hypothesis' (ETH) and point out that in general these models must contain non-Gaussian corrections, already in order to correctly capture thermal mean-field theory, or to capture non-trivial OTOCs as well as their higher-order generalizations.
