Krylov Complexity in Quantum Field Theory [PDF]
Nuclear Physics B, 2023 In this paper, we study the Krylov complexity in quantum field theory and make a connection with the holographic “Complexity equals Volume” conjecture.

Review on Quantum Computing for Lattice Field Theory [PDF]
Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2023 In these proceedings, we review recent advances in applying quantum computing to lattice field theory. Quantum computing offers the prospect to simulate lattice field theories in parameter regimes that are largely inaccessible with the conventional Monte

Classical Gravitational Bremsstrahlung from a Worldline Quantum Field Theory. [PDF]
Physical Review Letters, 2021 Using the recently established formalism of a worldline quantum field theory description of the classical scattering of two spinless black holes, we compute the far-field time-domain waveform of the gravitational waves produced in the encounter at ...

Wick Rotation and the Positivity of Energy in Quantum Field Theory [PDF]
Quarterly Journal of Mathematics, 2021 We propose a new axiom system for unitary quantum field theories on curved space-time backgrounds, by postulating that the partition function and the correlators extend analytically to a certain domain of complex-valued metrics.

Lectures on entanglement in quantum field theory [PDF]
Proceedings of Theoretical Advanced Study Institute 2021 — PoS(TASI2021), 2022 These notes grew from a series of lectures given by the authors during the last decade. They will be published in the proceedings of TASI 2021. After a brief introduction to quantum information theory tools, they are organized in four chapters covering ...

A detector-based measurement theory for quantum field theory [PDF]
Physical Review D, 2021 We propose a measurement theory for quantum fields based on measurements made with localized non-relativistic systems that couple covariantly to quantum fields (like the Unruh-DeWitt detector). Concretely, we analyze the positive operator-valued measure (

Journal of High Energy Physics, 2022 Although the mathematics of anyon condensation in topological phases has been studied intensively in recent years, a proof of its physical existence is tantamount to constructing an effective Hamiltonian theory. In this paper, we concretely establish the

Electric dipole moments of neutron and heavy quarks c, t in CP violating U(1)XSSM
Nuclear Physics B, 2022 We study and analyze the electric dipole moments (EDMs) of neutron and heavy quarks c, t in a CP-violating (CPV) supersymmetric U(1) extension of the standard model called U(1)XSSM, whose local gauge group is U(1)X×SU(3)C×SU(2)L×U(1)Y.

Energy conditions in general relativity and quantum field theory [PDF]
Classical and quantum gravity, 2020 This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results and applications, complemented with a few new derivations and discussions.
