Geometric conservation in curved spacetime and entropy
Sinya Aoki, Yoshimasa Hidaka, Kiyoharu Kawana +1
We provide an improved definition of new conserved quantities derived from the energy-momentum tensor in curved spacetime by introducing an additional scalar function. We find that…
Effective Brane Field Theory with Higher-form Symmetry
Yoshimasa Hidaka, Kiyoharu Kawana
We propose an effective field theory for branes with higher-form symmetry as a generalization of ordinary Landau theory, which is an extension of the previous work by Iqbal and McG…
Note on general functional flows in equilibrium systems
Kiyoharu Kawana
We study the response of generating functionals to a variation of parameters (couplings) in equilibrium systems i.e. in quantum field theory (QFT) and equilibrium statistical mecha…
Bulk modified gravity from a thermal CFT by the conformal flow
Sinya Aoki, János Balog, Kiyoharu Kawana +1
We construct a bulk spacetime from a boundary CFT, free scalar model, at finite temperature using a smearing technique, called a conformal flow. The bulk metric is construct…
Quantum phase transition and absence of quadratic divergence in generalized quantum field theories
Hikaru Kawai, Kiyoharu Kawana, Kin-ya Oda +1
In ordinary thermodynamics, around first-order phase transitions, the intensive parameters such as temperature and pressure are automatically fixed to the phase transition point wh…
