Summary: We investigate the effects of two-spin entanglement buildup and decay through phase interactions in a finite environment of surrounding spins. We find that non-Markovian dephasing caused by the spin environment can be solved exactly and compared to a Markovian treatment based on collision models. In two case studies, we demonstrate that non-Markovianity accelerates dephasing and degrades entanglement, but additional three-body interactions and random reset operations can mitigate this degradation.

Summary: Imaging biomolecules with ionizing radiation like electrons causes radiation damage, limiting the number of high-energy electrons available for imaging and resulting in low signal-to-noise ratios. Radiation damage alters molecular structures and dampens high-resolution details from the microscope and detector's transfer functions. Traditional electron microscopy is restricted by radiation damage in handling particle size and sample heterogeneity.

Summary: The observable effect of the interplay between nuclear and electronic dynamics on multidimensional electronic spectra can be accounted for by response functions. In this study, we derive analytical expressions for the response functions corresponding to a specific class of model systems, which are characterized by coupling between electronic states and vibrational degrees of freedom, as well as nonadiabatic couplings between pairs of diabatic states. The approach is applied to derive third-order response functions for various physical processes and comparisons with numerical calculations provide evidence of convergence in selected cases.

Summary: Multidimensional spectroscopy can reveal the interaction between nuclear and electronic dynamics in various molecular and solid-state systems. A proposed approach for calculating response functions involves the explicit derivation of the vibrational state, which coincides with a multimode squeezed coherent state in quantum-optical formalism. This method simplifies the numerical derivation of response functions and provides a quantitative substantiation of their interpretation in terms of vibrational wave packet dynamics.

Summary: The quantum capacitance of a few-particle system capacitively coupled to a metal gate can be used to distinguish different quantum states. This concept is extended to multiple voltages by introducing the quantum capacitance matrix. By using this matrix formalism, the dependence of the quantum capacitance on voltage oscillations in the parameter space can be determined, and the optimal combination of gate voltages can be identified. As an application, this approach is used to optimize the discrimination between states with different particle numbers and/or total spins in a quantum dot array.

Summary: In this study, two-hole states in prototypical coupled Si and Ge quantum dots were investigated using different theoretical approaches. It was found that, in the weak interdot regime, the ground state and first excited multiplet of the two-hole system displayed a high degree of mixing, even in the limit of purely heavy-hole states. The light-hole component further induced mixing and weak coupling between spinors characterized by different permutational symmetries.
