Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therm…

Tunable Chaos in the Finite Mean SYK Model
Arkaprava Mukherjee, Sumilan Banerjee, Sandip P. Trivedi +1
The complex Sachdev-Ye-Kitaev (SYK) model, featuring fermions with all-to-all interactions, serves as a dual paradigm for understanding non-Fermi liquid behavior and the holographi…

Multipartite information in sparse SYK models
Norihiro Iizuka, Arkaprava Mukherjee, Sunil Kumar Sake +1
In quantum field theories that admit gravity dual, specific inequalities involving entanglement entropy between arbitrary disjoint spatial regions hold. An example is the negativit…
