Orbital character and photoemission signatures of the A-pocket in infinite-layer nickelates
Leonard M. Verhoff, Michael Seidl, Liang Si +1
The orbital character of the so-called -pocket in infinite-layer nickelates remains under debate. We investigate bulk NdNiO using density-functional theory combined with dyn…
Beyond the conventional Emery model: crucial role of long-range hopping for cuprate superconductivity
Eric Jacob, M. O. Malcolms, Viktor Christiansson +6
The Emery model is the quintessential model for cuprate superconductors. In his eponymous paper, Emery only considered the next-nearest-neighbor oxygen-copper hopping. Later, also…
Surfaces and interfaces of infinite-layer nickelates studied by dynamical mean-field theory
Leonard M. Verhoff, Liang Si, Karsten Held
Infinite-layer nickelate superconductors are typically synthesized as thin films and thus include, besides the more bulk-like inner layers, distinct surface and interface layers in…
Diagnosing phase transitions through time-scale entanglement
Stefan Rohshap, Hirone Ishida, Frederic Bippus +5
Spatial entanglement of quantum states has become a central paradigm of many-body physics. Here, we unearth a fundamentally different form of entanglement, the entanglement between…
Demonstration of domain wall current in MgO-doped lithium niobate single crystals up to 400 °C
Hendrik Wulfmeier, Uliana Yakhnevych, Cornelius Boekhoff +12
Conductive ferroelectric domain walls (DWs) represent a promising topical system for the development of nanoelectronic components and device sensors to be operational at elevated t…
High-temperature domain wall current in Mg-doped lithium niobate single crystals up to 400°C
Uliana Yakhnevych, Marlo Kunzner, Leonard M. Verhoff +6
Conductive ferroelectric domain walls (DWs) represent a promising topical system for the development of nanoelectronic components and devices. DWs show very different properties as…
Ferroelectric to paraelectric structural transition in LiTaO and LiNbO
Felix Bernhardt, Leonard M. Verhoff, Nils A. Schäfer +13
The ferroelectric to paraelectric phase transition in LiTaO and in pure as well as Mg doped LiNbO is investigated theoretically by atomistic calculations in the framework o…
Phase Transformation in Lithium Niobate-Lithium Tantalate Solid Solutions (LiNbTaO)
Fatima El Azzouzi, Detlef Klimm, Alexander Kapp +6
The investigation of the structural phase transition in the vicinity of the Curie temperature of LiNbTaO crystals is motivated by the expected combination of…
