High-field transport and hot electron noise in GaAs from first principles: role of two-phonon scattering
Peishi S. Cheng, Jiace Sun, Shi-Ning Sun +2
High-field charge transport in semiconductors is of fundamental interest and practical importance. While the \textit{ab initio} treatment of low-field transport is well-developed,…
A generalized class of strongly stable and dimension-free T-RPMD integrators
Jorge L. Rosa-RaÃces, Jiace Sun, Nawaf Bou-Rabee +1
Recent work shows that strong stability and dimensionality freedom are essential for robust numerical integration of thermostatted ring-polymer molecular dynamics (T-RPMD) and path…
Experimental demonstration of scalable cross-entropy benchmarking to detect measurement-induced phase transitions on a superconducting quantum processor
Hirsh Kamakari, Jiace Sun, Yaodong Li +5
Quantum systems subject to random unitary evolution and measurements at random points in spacetime exhibit entanglement phase transitions which depend on the frequency of these mea…
Stochastic tensor contraction for quantum chemistry
Jiace Sun, Garnet Kin-Lic Chan
Many computational methods in ab initio quantum chemistry are formulated in terms of high-order tensor contractions, whose cost determines the size of system that can be studied. W…
Molecular Energy Learning Using Alternative Blackbox Matrix-Matrix Multiplication Algorithm for Exact Gaussian Process
Jiace Sun, Lixue Cheng, Thomas F. Miller
We present an application of the blackbox matrix-matrix multiplication (BBMM) algorithm to scale up the Gaussian Process (GP) training of molecular energies in the molecular-orbita…
Towards chemical accuracy with shallow quantum circuits: A Clifford-based Hamiltonian engineering approach
Jiace Sun, Lixue Cheng, Weitang Li
Achieving chemical accuracy with shallow quantum circuits is a significant challenge in quantum computational chemistry, particularly for near-term quantum devices. In this work, w…
