Qubit Regularization and Qubit Embedding Algebras
Hanqing Liu, Shailesh Chandrasekharan
Qubit regularization is a procedure to regularize the infinite dimensional local Hilbert space of bosonic fields to a finite dimensional one, which is a crucial step when trying to…
A spin-charge flip symmetric fixed point in 2+1d with massless Dirac fermions
Hanqing Liu
We study a quantum phase transition of electrons on a two-dimensional square lattice. Our lattice model preserves the full symmetry of free spin- Dirac…
Quantum Criticality of Anti-ferromagnetism and Superconductivity with Relativity
Hanqing Liu, Emilie Huffman, Shailesh Chandrasekharan +1
We study a quantum phase transition from a massless to massive Dirac fermion phase in a new two-dimensional bipartite lattice model of electrons that is amenable to sign-free quant…
Qudit circuits with SU(d) symmetry: Locality imposes additional conservation laws
Iman Marvian, Hanqing Liu, Austin Hulse
Local symmetric quantum circuits provide a simple framework to study the dynamics and phases of complex quantum systems with conserved charges. However, some of their basic propert…
