A Renormalization-Group Study of Interacting Bose-Einstein Condensates: II. Anomalous Dimension for at Finite Temperatures
Takafumi Kita
We study the anomalous dimension of homogeneous interacting single-component Bose-Einstein condensates at finite temperatures for dimensions. This is defined…
Variational Approach to Many-Body Problems Incorporating Many-Body Effects at Finite Temperature
Akimitsu Kirikoshi, Wataru Kohno, Takafumi Kita
We develop a variational approach at finite temperature that incorporates many-body correlation self-consistently. The grand potential is constructed in terms of Green's function e…
A Renormalization-Group Study of Interacting Bose-Einstein condensates: Absence of the Bogoliubov Mode below Four () and Three () Dimensions
Takafumi Kita
We derive exact renormalization-group equations for the -point vertices () of interacting single-component Bose-Einstein condensates based on the vertex expansio…
Drastic enhancement of the thermal Hall angle in a -wave superconductor
Hikaru Ueki, Hiroki Morita, Marie Ohuchi +1
A drastic enhancement of the thermal Hall angle in -wave superconductors was observed experimentally in a cuprate superconductor and in CeCoIn at low temperatures and very w…
