We have introduced an ultra-low-temperature, high-magnetic-field environment of 5 millikelvin and 12 tesla.
In our laboratory, we aim to realize a toy model of the “quantum universe”—a Planck-scale cosmology that emerges in the earliest stages of the Big Bang—on a semiconductor chip.
To achieve this, it is essential to cool samples to extremely low temperatures in order to suppress thermal noise to the ultimate limit. Our new dilution refrigerator and superconducting magnet system can provide an environment of 5 millikelvin and 12 tesla.
