Cavity Control of Strongly Correlated Electrons Beyond Resonant Coupling
Lukas Grunwald, Xinle Cheng, Emil Viñas Boström +4
Interfacing materials with electromagnetic cavities offers a route to modify equilibrium properties through structured vacuum fluctuations. The coupling between light and correlate…
Cavity control of multiferroic order in single-layer NiI
Chongxiao Fan, Emil Viñas Boström, Xinle Cheng +5
Controlling materials through their interactions with electromagnetic vacuum fluctuations is an emergent frontier in material engineering. Although recent experiments have demonstr…
Cavity Spectroscopy for Strongly Correlated Systems
Lukas Grunwald, Emil Viñas Boström, Mark Kamper Svendsen +2
Embedding materials in optical cavities has emerged as an intriguing perspective for controlling quantum materials, but a key challenge lies in measuring properties of the embedded…
Dynamical Onset of Light-Induced Unconventional Superconductivity -- a Yukawa-Sachdev-Ye-Kitaev study
Lukas Grunwald, Giacomo Passetti, Dante M. Kennes
We investigate the dynamical onset of superconductivity in the exactly solvable Yukawa-Sachdev-Ye-Kitaev model. It hosts an unconventional superconducting phase that emerges out of…
-symmetric, non-Hermitian quantum many-body physics -- a methodological perspective
Volker Meden, Lukas Grunwald, Dante M. Kennes
We review the methodology to theoretically treat parity-time- (-) symmetric, non-Hermitian quantum many-body systems... (For the full abstract see paper)
Can neural quantum states learn volume-law ground states?
Giacomo Passetti, Damian Hofmann, Pit Neitemeier +3
We study whether neural quantum states based on multi-layer feed-forward networks can find ground states which exhibit volume-law entanglement entropy. As a testbed, we employ the…
Functional renormalization group for non-Hermitian and -symmetric systems
Lukas Grunwald, Volker Meden, Dante M. Kennes
We generalize the vertex expansion approach of the functional renormalization group to non-Hermitian systems. As certain anomalous expectation values might not vanish, additional t…
