Exciton-spin interactions in antiferromagnetic charge-transfer insulators
Tatsuya Kaneko, Yuta Murakami, Denis Golež +2
We derive exciton-spin interactions from a microscopic correlated model that captures important aspects of the physics of charge-transfer (CT) insulators to address magnetism assoc…
Two-Dimensional Moiré Polaronic Electron Crystals
Eric A. Arsenault, Yiliu Li, Birui Yang +12
Two-dimensional moiré materials have emerged as the most versatile platforms for realizing quantum phases of electrons. Here, we explore the stability origins of correlated states…
Magnetism and Metallicity in Moiré Transition Metal Dichalcogenides
Patrick Tscheppe, Jiawei Zang, Marcel Klett +8
The ability to control the properties of twisted bilayer transition metal dichalcogenides in situ makes them an ideal platform for investigating the interplay of strong correlation…
Picosecond volume expansion drives a later-time insulator-metal transition in a nano-textured Mott Insulator
Anita Verma, Denis Golež, Oleg Yu. Gorobtsov +24
Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrins…
Topological superconductivity in doped magnetic moiré semiconductors
Valentin Crépel, Daniele Guerci, Jennifer Cano +2
We show that topological superconductivity may emerge upon doping of transition metal dichalcogenide heterobilayers above an integer-filling magnetic state of the topmost valence m…
Screening Induced Crossover between Phonon- and Plasmon-Mediated Pairing in Layered Superconductors
Yann in 't Veld, Mikhail I. Katsnelson, Andrew J. Millis +1
Two-dimensional (2D) metals can host gapless plasmonic excitations, which strongly couple to electrons and thus may significantly affect superconductivity in layered materials. To…
