Quantum entanglement of ions for light dark matter detection
Journal of High Energy PhysicsA detection scheme is explored for light dark matter, such as axion dark matter or dark photon dark matter, using a Paul ion trap system. We first demonstrate that a qubit, constructed from the ground and first excited states of vibrational modes of ions

Krylov Complexity in Quantum Field Theory
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.

Lepton flavor violating decays lj → liγγ
Nuclear Physics BIn this paper, we study the lepton flavor violating decays of the lj→liγγ (j=2, 3; i=1, 2) processes under the U(1)XSSM. The U(1)XSSM is the addition of three singlet new Higgs superfields and right-handed neutrinos to the minimal supersymmetric standard

Quantum Thermodynamics at Strong Coupling: Operator Thermodynamic Functions and Relations
Entropy, 2018 Identifying or constructing a fine-grained microscopic theory that will emerge under specific conditions to a known macroscopic theory is always a formidable challenge.

Quantum field theory of geometry [PDF]
, 1999 Over the past five years, there has been significant progress on the problem of quantization of diffeomorphism covariant field theories with {\it local} degrees of freedom. The absence of a background space-time metric in these theories gives rise to a host of conceptual and technical difficulties because most of the familiar methods from axiomatic ...

Symmetry fractionalized (irrationalized) fusion rules and two domain-wall Verlinde formulae
Journal of High Energy PhysicsWe investigate the composite systems consisting of topological orders separated by gapped domain walls. We derive a pair of domain-wall Verlinde formulae, that elucidate the connection between the braiding of interdomain excitations labeled by pairs of ...

Electron-nuclear decoupling at a spin clock transition
Communications Physics, 2023 Magnetic molecules have chemically tunable electronic states that could be used for quantum technologies, but they are often surrounded by a nuclear spin bath causing decoherence. In this study, the authors experimentally investigate the electron-nuclear

Jets and quantum field theory [PDF]
Physics Letters B, 1996 We discuss quantum-field-theoretic interpretation of the family of observables (the so-called C-algebra) introduced in [ F.V.Tkachov: Preprint FERMILAB-PUB-95/191-T] for a systematic description of multijet structure of multiparticle final states at high energies.

Nambu–Jona-Lasinio model in a parallel electromagnetic field
Physics Letters B, 2018 We explore the features of the UA(1) and chiral symmetry breaking of the Nambu–Jona-Lasinio model without the Kobayashi–Maskawa–'t Hooft determinant term in the presence of a parallel electromagnetic field. We show that the electromagnetic chiral anomaly

T T ¯ $$ T\overline{T} $$ -deformation and long range spin chains
Journal of High Energy Physics, 2020 We point out that two classes of deformations of integrable models, developed completely independently, have deep connections and share the same algebraic origin. One class includes the T T ¯ $$ T\overline{T} $$ -deformation of 1+1 dimensional integrable
