Angle-resolved photoemission spectroscopy (ARPES), with its exceptional sensitivity to both
the binding energy and the momentum of valence electrons in solids, provides unparalleled …

Hard x-ray photoelectron spectroscopy (HAXPES) is establishing itself as an essential
technique for the characterisation of materials. The number of specialised photoelectron …

Moiré superlattices in atomically thin van der Waals heterostructures hold great promise for
extended control of electronic and valleytronic lifetimes,,,,,–, the confinement of excitons in …

Repulsive and long-range exciton–exciton interactions are crucial for the exploration of one-
dimensional (1D) correlated quantum phases in the solid state. However, the experimental …

We demonstrate the feasibility of the time-linear scaling formulation of the GW method [Phys.
Rev. Lett. 124, 076601 (2020) PRLTAO 0031-9007 10.1103/PhysRevLett. 124.076601] for …

In the last decade, there has been a proliferation of laser sources for time-and angle-
resolved photoemission spectroscopy (TR-ARPES), building on the proven capability of this …

We present a time-linear scaling method to simulate open and correlated quantum systems
out of equilibrium. The method inherits from many-body perturbation theory the possibility to …

Van der Waals (vdW) materials at their 2D limit are diverse, flexible, and unique laboratories
to study fundamental quantum phenomena and their future applications. Their novel …

The light-mediated interaction of fermionic and bosonic excitations governs the
optoelectronic properties of condensed matter systems. In photoexcited semiconductors, the …

Excitons–two-particle correlated electron-hole pairs–are the dominant low-energy optical
excitation in the broad class of semiconductor materials, which range from classical silicon …
