A sine-square deformation approach to quantum critical points in one-dimensional systems
Yuki Miyazaki, Shiori Tanigawa, Giacomo Marmorini +2
We propose a method to determine the quantum phase boundaries of one-dimensional systems using sine-square deformation (SSD). Based on the proposition, supported by several exactly…
