  • Critical exponents for the one-dimensional Hubbard model 
    Frahm, Holger; Korepin, V.E. (College Park (Maryland) : American Physical Society, 1990)
    Using results on the scaling of energies with the size of the system and the principles of conformal quantum field theory, we calculate the asymptotics of correlation functions for the one-dimensional Hubbard model in the ...
  • Gravitational Redshift Induces Quantum Interference 
    Bruschi, David Edward; Schell, Andreas Wolfgang (Berlin : Wiley-VCH, 2022)
    Quantum field theory in curved spacetime is used to show that gravitational redshift induces a unitary transformation on the quantum state of propagating photons. It is found that the transformation is a mode-mixing ...
  • Higher-derivative superparticle in AdS3 space 
    Kozyrev, Nikolay; Krivonos, Sergey; Lechtenfeld, Olaf (College Park (Maryland) : American Physical Society, 2016)
    Employing the coset approach we construct component actions for a superparticle moving in AdS3 with N=(2,0), D=3 supersymmetry partially broken to N=2, d=1. These actions may contain higher time-derivative terms, which are ...
  • Inferring effective field observables from a discrete model 
    Bény, Cédric (Bristol : Institute of Physics Publishing, 2017)
    A spin system on a lattice can usually be modeled at large scales by an effective quantum field theory. A key mathematical result relating the two descriptions is the quantum central limit theorem, which shows that certain ...
  • The renormalization group via statistical inference 
    Beny, Cedric; Osborne, Tobias J. (Bristol : IOP Publishing Ltd., 2015-08-05)
    In physics, one attempts to infer the rules governing a system given only the results of imperfect measurements. Hence, microscopic theories may be effectively indistinguishable experimentally. We develop an operationally ...
