Nonequilibrium relaxation exponentially delays the onset of quantum diffusion
Srijan Bhattacharyya, Thomas Sayer, Andrés Montoya-Castillo
Predicting the exact many-body quantum dynamics of polarons in materials with strong carrier-phonon interactions presents a fundamental challenge, often necessitating one to adopt…
Space-local memory in generalized master equations: Reaching the thermodynamic limit for the cost of a small lattice simulation
Srijan Bhattacharyya, Thomas Sayer, Andrés Montoya-Castillo
The exact quantum dynamics of lattice models can be computationally intensive, especially when aiming for large system sizes and extended simulation times necessary to converge tra…
Generalized quantum master equations can improve the accuracy of semiclassical predictions of multitime correlation functions
Thomas Sayer, Andrés Montoya-Castillo
Multitime quantum correlation functions are central objects in physical science, offering a direct link between experimental observables and the dynamics of an underlying model. Wh…
Mori generalized master equations offer an efficient route to predict and interpret transport
Srijan Bhattacharyya, Thomas Sayer, Andrés Montoya-Castillo
Predicting how a material's microscopic structure and dynamics determine its transport properties remains a fundamental challenge. To alleviate this task's often prohibitive comput…
