Scalable simulation of non-Markovian quantum transport by stochastic-phase bath reduction
Zhen Huang, Lin Lin, Pinchen Xie
Accurate simulations of non-Markovian quantum transport remain limited to small systems, and a key bottleneck is that each system site requires an independent set of quantum bath o…
Deuteration removes quantum dipolar defects from KDP crystals
Bingjia Yang, Pinchen Xie, Roberto Car
The structural, dielectric, and thermodynamic properties of the hydrogen-bonded ferroelectric crystal potassium dihydrogen phosphate (), KDP for short, differ si…
