Classical Simulations of Quantum Field Theory in Curved Spacetime I: Fermionic Hawking-Hartle Vacua from a Staggered Lattice Scheme

We numerically compute renormalized expectation values of quadratic operators in a quantum field theory (QFT) of free Dirac fermions in curved two-dimensional (Lorentzian) spacetime. Expand abstract.

Supersymmetric Soliton $\sigma$-models from Non-Lorentzian Field Theories

Recently, a class of non-Lorentzian supersymmetric Lagrangian field theories was considered, in some cases describing M-theory brane configurations, but more generally found as fixed points of non-Lorentzian RG flows induced upon Lorentzian theories. Expand abstract.

Late transition-metal oxides with infinite-layer structure: nickelate vs. cuprate

The correlated electronic structure of the infinite-layer compounds NdNiO$_2$ and SrCuO$_2$ at stoichiometry and with finite hole doping is compared. Expand abstract.

High-precision nuclear forces from chiral EFT: State-of-the-art, challenges and outlook

We outline the conceptual foundations of nuclear chiral effective field theory, discuss all steps needed to compute nuclear observables starting from the effective chiral Lagrangian and consider selected applications in the two- and few-nucleon sectors. Expand abstract.

Proximity effect in a heterostructure of a high $T_c$ superconductor with a topological insulator from Dynamical mean field theory

The latter is described by the one-band Hubbard model and is treated with cluster dynamical mean field theory (CDMFT), the TI layers being included via the CDMFT self-consistency loop. Expand abstract.

Modeling Choice Paradoxes Under Risk: From Prospect Theories to Sampling-Based Accounts

Two alternative models, Transfer of Attention Exchange (TAX) and an extension of Decision Field Theory (DFTe), have been proposed as possible alternatives to CPT. Expand abstract.

Scalar-field potential for viable models in $f(R)$ theory

Galois symbol maps for abelian varieties over a $p$-adic field

We study the Galois symbol map associated to the multiplicative group and an abelian variety which has good ordinary reduction over a $p$-adic field. Expand abstract.
