A sine-square deformation approach to quantum critical points in one-dimensional systems
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 solved cases though not proven in full generality, that ``if a one-dimensional system is gapless, then the expectation...
