Light-Matter Interactions Beyond the Dipole Approximation in Extended Systems Without Multipole Expansion
Rishabh Dora, Roman Korol, Vishal Tiwari +2
We present a general theoretical framework to capture light-matter interactions beyond the electric-dipole approximation (EDA), applicable to extended nano- and microscale material…
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…
Bexcitonics: Quasi-particle approach to open quantum dynamics
Xinxian Chen, Ignacio Franco
We develop a quasiparticle approach to capture the dynamics of open quantum systems coupled to bosonic thermal baths of arbitrary complexity based on the Hierarchical Equations of…
