Dissipation in a finite-temperature atomic Josephson junction

Physical Review Research, 2022
We numerically demonstrate and characterize the emergence of distinct dynamical regimes of a finite temperature bosonic superfluid in an elongated Josephson junction generated by a thin Gaussian barrier over the entire temperature range where a well-formed condensate can be clearly identified.

Magnetic Tunnel Junction as an On-Chip Temperature Sensor [PDF]

Scientific Reports, 2017
AbstractTemperature sensors are becoming an increasingly important component in System-on-Chip (SoC) designs with increasing transistor scaling, power density and associated heating effects. This work explores a compact nanoelectronic temperature sensor based on a Magnetic Tunnel Junction (MTJ) structure. The MTJ switches probabilistically depending on
