Over the last decade impressive progress has been made in the theoretical understanding
of transport properties of clean, one-dimensional quantum lattice systems. Many physically …

Thanks to the high compression of the matrix product state (MPS) form of the wave function
and the efficient site-by-site iterative sweeping optimization algorithm, the density matrix …

Capturing non-Markovian dynamics of open quantum systems is generally a challenging
problem, especially for strongly interacting many-body systems. In this Letter, we combine …

A comprehensive picture of polaron and bipolaron physics is essential to understand the
optical absorption spectrum in many materials with electron-phonon interactions. In …

In this work, we study singlet fission in tetracene para-dimers, covalently linked by a phenyl
group. In contrast to most previous studies, we account for the full quantum dynamics of the …

In recent years, the time-dependent variational principle (TDVP) method based on the matrix
product state (MPS) wave function formulation has shown its great power in performing large …

The excited-state dynamics of organic molecules, molecular aggregates, and donor–
acceptor clusters is typically governed by the interplay of electronic excitations and, due to …

We introduce phonon state tomography (PST) as a diagnostic probe of electron dynamics in
solids whose phonons are optically excited by a laser pulse at initial time. Using a projected …

Quantum dynamics (QD) simulation is a powerful tool for interpreting ultrafast spectroscopy
experiments and unraveling their microscopic mechanism in out-of-equilibrium excited state …

Understanding the influence of vibrational degrees of freedom on transport through a
heterostructure poses considerable theoretical and numerical challenges. In this work, we …
