Boundary Criticality of Topological Quantum Phase Transitions in systems
Xiao-Chuan Wu, Yichen Xu, Hao Geng +2
We discuss the boundary critical behaviors of two dimensional quantum phase transitions with fractionalized degrees of freedom in the bulk, motivated by the fact that usually it is…
Some Information Theoretic Aspects of De-Sitter Holography
Hao Geng
Built on our observation that entangling surfaces of the boundary field theory are great co-dimension one spheres in the context of DS/dS correspondence, we study some information…
Non-Landau Quantum Phase Transitions and nearly-Marginal non-Fermi Liquid
Yichen Xu, Hao Geng, Xiao-Chuan Wu +2
Non-fermi liquid and unconventional quantum critical points (QCP) with strong fractionalization are two exceptional phenomena beyond the classic condensed matter doctrines, both of…
Deformation and the Complexity=Volume Conjecture
Hao Geng
Complexity in quantum physics measures how difficult a state can be reached from a reference state and more precisely it is the number of fundamental unitary gates we have to opera…
Distance Conjecture and De-Sitter Quantum Gravity
Hao Geng
Motivated by the early discovery of the gigantic landscape of string theory vacua, in recent years people switched direction to try to find constraints on low energy effective fiel…
Entropy, Entanglement and Swampland Bounds in DS/dS
Hao Geng, Sebastian Grieninger, Andreas Karch
We calculate the entanglement entropy of the de-Sitter (dS) static patch in the context of the DS/dS correspondence. Interestingly, we find that there exists a one parameter family…
