We develop a perturbative technique for solving Markovian quantum dissipative dynamics,
with the perturbation parameter being a small gap in the eigenspectrum. As an example, we …

Recently, a “unified” quantum master equation was derived and shown to be of the Gorini-
Kossakowski-Lindblad-Sudarshan form. This equation describes the dynamics of open …

Whether genuine quantum effects, particularly quantum coherences, can offer an advantage
to quantum devices is a topic of much interest. Here, we study a minimal model, the three …

Environment-induced steady-state quantum coherence (SSQC) is a captivating
phenomenon that challenges conventional understandings of decoherence. In this article …

Oscillations in time-dependent two-dimensional electronic spectra appear as evidence of
quantum coherence in light-harvesting systems related to electronic–vibrational resonant …

Open quantum systems with nearly degenerate energy levels have been shown to exhibit
long-lived metastable states in the approach to equilibrium, even when modelled with …

We introduce prethermal temperature probes for sensitive, fast, and robust temperature
estimation. While equilibrium thermal probes with a manifold of quasidegenerate excited …

The reaction coordinate (RC) technique is emerging as a significant tool in the study of
quantum dissipative dynamics and quantum thermodynamics. With the objective to further …

We consider incoherent excitation of multilevel quantum systems, eg, molecules with
multiple vibronic states. We show that (1) the geometric constraints of the matter–field …

The interplay between electronic and intramolecular high-frequency vibrational degrees of
freedom is ubiquitous in natural light-harvesting systems. Recent studies have indicated that …
