Nonadiabatic transition paths from quantum jump trajectories

Kavli Affiliate: David T. Limmer | First 5 Authors: Michelle C. Anderson, Addison J. Schile, David T. Limmer, , | Summary: We present a means of studying rare reactive pathways in open quantum systems using Transition Path Theory and ensembles of quantum jump trajectories. This approach allows for elucidation of reactive paths for dissipative, nonadiabatic […]

Minimal Joint Entropy and Order-Preserving Couplings

Kavli Affiliate: Feng Wang | First 5 Authors: Ya-Jing Ma, Feng Wang, Xian-Yuan Wu, Kai-Yuan Cai, | Summary: This paper focuses on the extreme-value problem for Shannon entropy of the joint distribution with given marginals. It is proved that the minimum-entropy coupling must be of order-preserving, while the maximum-entropy coupling coincides with the independent one. […]

Gate-Tunable Spin-Orbit Coupling in a Germanium Hole Double Quantum Dot

Kavli Affiliate: Ke Wang | First 5 Authors: He Liu, Ting Zhang, Ke Wang, Fei Gao, Gang Xu | Summary: Hole spins confined in semiconductor quantum dot systems have gained considerable interest for their strong spin-orbit interactions (SOIs) and relatively weak hyperfine interactions. Here we experimentally demonstrate a tunable SOI in a double quantum dot […]

The interstellar medium of high-redshift galaxies: Gathering clues from C III] and [C II] lines

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Vladan Markov, Stefano Carniani, Livia Vallini, Andrea Ferrara, Andrea Pallottini | Summary: A tight relation between [C II] line luminosity and the star formation rate (SFR) has been observed for local galaxies. At high redshift (z > 5), galaxies instead deviate downwards from the local $Sigma$_[C II] […]

The ISM of high-redshift galaxies: clues from C III] and [C II] lines

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Vladan Markov, Stefano Carniani, Livia Vallini, Andrea Ferrara, Andrea Pallottini | Summary: A tight relation between [C II] $ 158 {rm{mu m}}$ line luminosity and star formation rate (SFR) is observed in local galaxies. At $z > 5$, galaxies instead deviate downwards from the local $Sigma_{rm{[C II]}}-Sigma_{rm{SFR}}$ […]

Enhanced superconductivity by near-neighbor attraction in the doped Hubbard model

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Yao Wang, Jiajia Wen, Young Lee, Thomas Devereaux | Summary: Recent experiment has unveiled an anomalously strong electron-electron attraction in one-dimensional copper-oxide chain Ba$_{2-x}$Sr$_x$CuO$_{3+delta}$. While the near-neighbor electron attraction $V$ in the one-dimensional extended Hubbard chain has been examined recently, its effect in the Hubbard […]
