Truncated Gaussian basis approach for simulating many-body dynamics
Nico Albert, Yueshui Zhang, Hong-Hao Tu
We propose a Truncated Gaussian Basis Approach (TGBA) for simulating the dynamics of quantum many-body systems. The approach constructs an effective Hamiltonian within a reduced su…
Crosscap states and duality of Ising field theory in two dimensions
Yueshui Zhang, Ying-Hai Wu, Lei Wang +1
We propose two distinct crosscap states for the two-dimensional (2D) Ising field theory. These two crosscap states, identifying Ising spins or dual spins (domain walls) at antipoda…
Efficient conversion from fermionic Gaussian states to matrix product states
Tong Liu, Ying-Hai Wu, Hong-Hao Tu +1
Fermionic Gaussian states are eigenstates of quadratic Hamiltonians and are widely used in quantum many-body problems. We propose a highly efficient algorithm that converts fermion…
Extracting the Luttinger parameter from a single wave function
Bi-Yang Tan, Yueshui Zhang, Hua-Chen Zhang +4
The low-energy physics of Tomonaga-Luttinger liquids (TLLs) is controlled by the Luttinger parameter. We demonstrate that this parameter can be extracted from a single wave functio…
