In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many noisy physical qubits. The large physical-qubit overhead typically as

Fermi surface reconstruction in strained La$_3$Ni$_2$O$_{7}$ on LaAlO$_3$(001) and SrTiO$_3$(001)

Autor: Geisler, Benjamin, Hamlin, James J., Stewart, Gregory R., Hennig, Richard G., Hirschfeld, P. J.

We explore the structural and electronic properties of the bilayer nickelate La3Ni2O7 on LaAlO3(001) and SrTiO3(001) by using density functional theory including a Coulomb repulsion term. For La$_3$Ni$_2$O$_{7}$/LaAlO$_3$(001), we find that compressi

Topological Twisting of 4d $\mathcal{N}=2$ Supersymmetric Field Theories

Autor: Moore, Gregory W., Saxena, Vivek, Singh, Ranveer Kumar

We discuss what topological data must be provided to define topologically twisted partition functions of four-dimensional $\mathcal{N}=2$ supersymmetric field theories. The original example of Donaldson-Witten theory depends only on the diffeomorphis

Crystal to liquid cross-over in the active Calogero-Moser model

Autor: Santra, Saikat, Touzo, Leo, Dasgupta, Chandan, Dhar, Abhishek, Dutta, Suman, Kundu, Anupam, Doussal, Pierre Le, Schehr, Gregory, Singh, Prashant

We consider a one-dimensional system comprising of $N$ run-and-tumble particles confined in a harmonic trap interacting via a repulsive inverse-square power-law interaction. This is the ``active" version of the Calogero-Moser system where the particl

Anticipatory Planning for Performant Long-Lived Robot in Large-Scale Home-Like Environments

Autor: Talukder, Md Ridwan Hossain, Arnob, Raihan Islam, Stein, Gregory J.

We consider the setting where a robot must complete a sequence of tasks in a persistent large-scale environment, given one at a time. Existing task planners often operate myopically, focusing solely on immediate goals without considering the impact o
