Probing Planckian physics in de Sitter space with quantum correlations
Jun Feng, Yao-Zhong Zhang, Mark D. Gould +3
We study the quantum correlation and quantum communication channel of both free scalar and fermionic fields in de Sitter space, while the Planckian modification presented by the ch…
Notes on teleportation in an expanding space
Jun Feng, Wen-Li Yang, Yao-Zhong Zhang +1
We investigate the quantum teleportation between a conformal detector Alice and an inertial detector Bob in de Sitter space in two schemes, (i) one uses free scalar modes and (ii)…
Deconfined quantum criticality and generalised exclusion statistics in a non-hermitian BCS model
Jon Links, Amir Moghaddam, Yao-Zhong Zhang
We present a pairing Hamiltonian of the Bardeen-Cooper-Schrieffer form which exhibits two quantum critical lines of deconfined excitations. This conclusion is drawn using the exact…
Quantum correlations with vacuum ambiguity in de Sitter space
Jun Feng, Cheng-Yi Sun, Wen-Li Yang +2
We study the quantum correlations of free scalar field with vacuum ambiguity of de Sitter space. We show the occurrence of degradation of quantum entanglement and quantum discord b…
Determinant representations for scalar products of the XXZ Gaudin model with general boundary terms
Kun Hao, Wen-Li Yang, Heng Fan +4
We obtain the determinant representations of the scalar products for the XXZ Gaudin model with generic non-diagonal boundary terms.
Novel quasi-exactly solvable models with anharmonic singular potentials
Davids Agboola, Yao-Zhong Zhang
We present new quasi-exactly solvable models with inverse quartic, sextic, octic and decatic power potentials, respectively. We solve these models exactly via the functional Bethe…
