Loophole-Robust Certification of Quantum Advantage
Prosanta Pal, Gargee Sharma, Ramakrishna Podila
Claims of quantum advantage should remain robust even when classical strategies have access to side information correlated with the benchmark under evaluation, just as Bell certifi…
A Preparation Nonstationarity Loophole in Superconducting-Qubit Bell Tests
Prosanta Pal, Shubhanshu Karoliya, Gargee Sharma +1
Bell or Clauser-Horne-Shimony-Holt (CHSH) tests on superconducting quantum processors are commonly interpreted under the assumption that repeated circuit executions sample a single…
Strain-induced Ettingshausen effect in spin-orbit coupled noncentrosymmetric metals
Gautham Varma K, Azaz Ahmad, Gargee Sharma
Elastic deformations couple with electronic degrees of freedom in materials to generate gauge fields that lead to interesting transport properties. Recently, it has been well studi…
Chiral anomaly and longitudinal magnetoconductance in pseudospin-1 fermions
Azaz Ahmad, Gargee Sharma
Chiral anomaly (CA), a hallmark of Weyl fermions, has emerged as a cornerstone of condensed matter physics following the discovery of Weyl semimetals. While the anomaly in pseudosp…
Nonlinear anomalous Hall effect in three-dimensional chiral fermions
Azaz Ahmad, Gautham Varma K., Gargee Sharma
Chiral fermionic quasiparticles emerge in certain quantum condensed matter systems such as Weyl semimetals, topological insulators, and spin-orbit coupled noncentrosymmetric metals…
Localization in two-dimensional fermions with arbitrary pseudospin
Adesh Singh, Gargee Sharma
In condensed matter, limited symmetry constraints allow free fermionic excitations to exist beyond the conventional Weyl and Dirac electrons of high-energy physics. These excitatio…
Geometry, anomaly, topology, and transport in Weyl fermions
Azaz Ahmad, Gautham Varma K., Gargee Sharma
Weyl fermions are one of the simplest objects that link ideas in geometry and topology to highenergy physics and condensed matter physics. Although the existence of Weyl fermions a…
Magnetotransport in spin-orbit coupled noncentrosymmetric and Weyl metals
Gautham Varma K, Azaz Ahmad, Sumanta Tewari +1
Recently, chiral anomaly (CA) has been proposed to occur in spin-orbit coupled noncentrosymmetric metals (SOC-NCMs), motivating CA to be a Fermi surface property rather than a Weyl…
High conductivity from cross-band electron pairing in flat-band systems
Maxim Trushin, Liangtao Peng, Gargee Sharma +2
Electrons in condensed matter may transition into a variety of broken-symmetry phase states due to electron-electron interactions. Applying diverse mean-field approximations to the…
Carrier transport theory for twisted bilayer graphene in the metallic regime
Gargee Sharma, Indra Yudhistira, Nilotpal Chakraborty +4
Understanding the normal-metal state transport in twisted bilayer graphene near magic angle is of fundamental importance as it provides insights into the mechanisms responsible for…
