Enhanced Superconductivity in Proximity to Peaks in Densities of States
Joshua Althüser, Ilya M. Eremin, Götz S. Uhrig
For the BCS theory of superconductivity, the electron-phonon interaction is transformed to an attractive electron-electron interaction in the vicinity of the Fermi energy only. At…
Experimental signature of transient symmetry breaking in a cavity superconductor
Siyu Duan, Jingbo Wu, Xiaoqing Jia +5
Transient states of matter far from equilibrium may exhibit physical properties beyond those allowed by the equilibrium-state crystalline symmetries. We explore ultrafast and direc…
Enhanced superconductivity in the compressively strained bilayer nickelate thin films by pressure
Qing Li, Jianping Sun, Steffen Boetzel +9
The discovery of high temperature superconductivity in the nickelate system has stimulated enormous interest in the community of condensed matter physics. Recently, superconductivi…
Superconducting gap structure and bosonic mode in La2PrNi2O7 thin films at ambient pressure
Shengtai Fan, Mengjun Ou, Marius Scholten +7
The recent discovery of high temperature superconductivity in nickelate systems has generated tremendous interests in the field of superconductivity. The core issue to understand t…
Antiferromagnetism and spin excitations in a two-dimensional non-Hermitian Hatano-Nelson flux model
Eduard Naichuk, Ilya M. Eremin, Jeroen van den Brink +1
The one-dimensional Hatano-Nelson model with non-reciprocal hoppings is a prominent example of a relatively simple non-Hermitian quantum-mechanical system, which allows to study va…
Low-energy perspective of interacting electrons in the normal state of superconducting bilayer nickelate
Frank Lechermann, Steffen Bötzel, Ilya M. Eremin
Developing a low-energy model is essential for understanding unconventional superconductivity in bilayer nickelate LaNiO. Here, we analyze distinct low-energy scenarios…
