Correlation-assisted spin-selective metallicity in strained and bilayer altermagnets

Marnin J. Di Nunzio, Frank Lechermann, Ilya M. Eremin

Altermagnets combine vanishing net magnetization with a momentum-dependent spin-split electronic structure, providing a route to spin-polarized carriers without ferromagnetism. Her…

Manifest charge-transfer physics in T $^{'}$ -La $_{2}$ NiO $_{4}$

Wiktoria Lewandowski, Steffen Bötzel, Ilya M. Eremin +1

The La $_{2}$ NiO $_{4}$ compound stabilizes in nature in the so-called T structure with octahedral oxygen coordination of the Ni site. Motivated by a similarly existing polymorph for La$…

Density waves in low-pressure bilayer nickelates

Lauro B. Braz, Steffen Bötzel, Frank Lechermann +4

The low-pressure phase diagram of La $_{3}$ Ni $_{2}$ O $_{7}$ provides an important reference for understanding its pressure-induced high-temperature superconductivity. While the spin-densit…

Co-operating multiorbital and nonlocal correlations in bilayer nickelate

Evgeny A. Stepanov, Steffen Bötzel, Ilya M. Eremin +1

The interplay of multiorbital physics and nonlocal self-energy effects is studied within an effective three-orbital model for the high-pressure normal state of superconducting bila…

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 La $_{3}$ Ni $_{2}$ O $_{7}$ . Here, we analyze distinct low-energy scenarios…

Interplay of orbital-selective Mott criticality and flat-band physics in La $_{3}$ Ni $_{2}$ O $_{6}$

Frank Lechermann, Steffen Bötzel, Ilya M. Eremin

Superconductivity in nickelates apparently takes place in two different Ni oxidation regimes, namely either for infinite-layer-type compounds close to Ni $^{+}$ , or for Ruddlesden-P…

Collective quantum phases in frustrated arrays of Josephson junctions

M. V. Fistul, O. Neyenhuys, B. Pernack +3

We study collective quantum phases and quantum phase transitions occurring in frustrated sawtooth arrays of small quantum Josephson junctions. Frustration is introduced through the…

Electronic instability, layer selectivity and Fermi arcs in La $_{3}$ Ni $_{2}$ O $_{7}$

Frank Lechermann, Steffen Bötzel, Ilya M. Eremin

Using advanced dynamical mean-field theory on a realistic level we study the normal-state correlated electronic structure of the high-pressure superconductor La $_{3}$ Ni $_{2}$ O $_{7}$ and…

Revisiting the metal-to-metal transition in $2 H$ -AgNiO $_{2}$

Jannik Gondolf, Ilya Eremin, Frank Lechermann

The layered delafossite compound AgNiO $_{2}$ with $2 H$ stacking symmetry undergoes a structural metal-to-metal transition at $T_{S} \sim 365$ K. It has been described in the past…
