Variational Method for Interacting Surfaces with Higher-Form Global Symmetries
Kiyoharu Kawana
We develop a variational method for interacting surface systems with higher-form global symmetries. As a natural extension of the conventional second-quantized Hamiltonian of inter…
On Virial Expansion in Hard Sphere Model
Kiyoharu Kawana
Virial expansion is a traditional approach in statistical mechanics that expresses thermodynamic quantities, such as pressure , as power series of density or chemical potential.…
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…
Density Renormalization Group for Classical Liquids
Satoshi Iso, Kiyoharu Kawana
We study response of liquid to a scale transformation, which generates a change of the liquid density, and obtain a set of differential equations for correlation functions. The set…
