TENSO: Software Package for Numerically Exact Open Quantum Dynamics Based on Efficient Tree Tensor Network Decomposition of the Hierarchical Equations of Motion
Juan C. Rodriguez-Betancourt, Michelle C. Anderson, Luchang Niu +2
TENSO is a versatile and powerful open-source software package for numerically exact simulations of the dynamics of quantum systems immersed in structured thermal environments. It…
Comparison between explicit and implicit discretization strategies for a dissipative thermal environment
Xinxian Chen, Ignacio Franco
We investigate strategies for simulating open quantum systems coupled to dissipative baths by comparing explicit wave function-based discretization [via multi-layer multi-configura…
Tree tensor network hierarchical equations of motion based on time-dependent variational principle for efficient open quantum dynamics in structured thermal environments
Xinxian Chen, Ignacio Franco
We introduce an efficient method TTN-HEOM for exactly calculating the open quantum dynamics for driven quantum systems interacting with highly structured bosonic baths by combining…
High-frequency tails in spectral densities
Roman Korol, Xinxian Chen, Ignacio Franco
Recent advances in numerically exact quantum dynamics methods have brought the dream of accurately modeling the dynamics of chemically complex open systems within reach. Path-integ…
Decoherence dynamics in molecular qubits: Exponential, Gaussian and beyond
Ignacio Gustin, Xinxian Chen, Ignacio Franco
In this work, we examine how the structure of system-bath interactions can determine commonly encountered temporal decoherence patterns, such as Gaussian and exponential decay, in…
