The local SYK model and its triple scaling limit
Takanori Anegawa, Norihiro Iizuka, Sunil Kumar Sake
We study a model of fermions with random couplings similar to conventional SYK with number of flavours of fermions, at large . Unlike the conventional SYK model, which has a…
JT Gravity in de Sitter Space and the Problem of Time
Kanhu Kishore Nanda, Sunil Kumar Sake, Sandip P. Trivedi
We discuss the canonical quantisation of JT gravity in de Sitter space, following earlier work by Henneaux, with particular attention to the problem of time. Choosing the dilaton a…
Sparse random matrices and Gaussian ensembles with varying randomness
Takanori Anegawa, Norihiro Iizuka, Arkaprava Mukherjee +2
We study a system of qubits with a random Hamiltonian obtained by drawing coupling constants from Gaussian distributions in various ways. This results in a rich class of system…
Is Action Complexity better for de Sitter space in Jackiw-Teitelboim gravity?
Takanori Anegawa, Norihiro Iizuka, Sunil Kumar Sake +1
Volume complexity in dS remains up to a critical time, after which it suddenly diverges. On the other hand, for the dS solution in JT gravity there is a linear dilat…
