Traversable wormhole in coupled SYK models with imbalanced interactions
Rafael Haenel, Sharmistha Sahoo, Timothy H. Hsieh +1
A pair of identical Sachdev-Ye-Kitaev (SYK) models with bilinear coupling forms a quantum dual of a traversable wormhole, with a ground state close to the so called thermofield dou…
Superconducting instabilities in a spinful Sachdev-Ye-Kitaev model
Étienne Lantagne-Hurtubise, Vedangi Pathak, Sharmistha Sahoo +1
We introduce a spinful variant of the Sachdev-Ye-Kitaev model with an effective time reversal symmetry, which can be solved exactly in the limit of a large number of degrees of…
Coupled wire construction of a topological phase with chiral tricritical Ising edge modes
Chengshu Li, Hiromi Ebisu, Sharmistha Sahoo +2
Tricritical Ising (TCI) phase transition is known to occur in several interacting spin and Majorana fermion models and is described in terms of a supersymmetric conformal field the…
Traversable wormhole and Hawking-Page transition in coupled complex SYK models
Sharmistha Sahoo, Étienne Lantagne-Hurtubise, Stephan Plugge +1
Recent work has shown that coupling two identical Sachdev-Ye-Kitaev (SYK) models can realize a phase of matter that is holographically dual to an eternal traversable wormhole. This…
Pretopological fractional excitations in the two-leg flux ladder
Marcello Calvanese Strinati, Sharmistha Sahoo, Kirill Shtengel +1
Topological order, the hallmark of fractional quantum Hall states, is primarily defined in terms of ground-state degeneracy on higher-genus manifolds, e.g. the torus. We investigat…
Paired parton quantum Hall states: a coupled wire construction
Alexander Sirota, Sharmistha Sahoo, Gil Young Cho +1
The Pfaffian fractional quantum Hall (FQH) states are incompressible non-Abelian topological fluids present in a half-filled electron Landau level, where there is a balanced popula…
Surfaces and Slabs of Fractional Topological Insulator Heterostructures
Sharmistha Sahoo, Alexander Sirota, Gil Young Cho +1
Fractional topological insulators (FTI) are electronic topological phases in dimensions enriched by time reversal (TR) and charge conservation symmetries. We focus o…
Coupled wire model of symmetric Majorana surfaces of topological superconductors
Sharmistha Sahoo, Zhao Zhang, Jeffrey C. Y. Teo
Time reversal symmetric topological superconductors in three spatial dimensions carry gapless surface Majorana fermions. They are robust against any time reversal symmetric single-…
