"Integrable matrix product states and overlaps”


címmel tartandó szemináriumára.


Kivonat:



Integrable matrix product states (MPS) appear in a variety of contexts 
ranging from quantum statistical physics to the AdS/CFT correspondence. 
A central quantity associated with these states is their overlap with 
Bethe eigenstates, which encodes physically important information, for 
example about quantum quenches and one-point functions in defect 
conformal field theories. Until recently, these overlaps were known only 
in a few special cases, but major progress has led to their exact and 
systematic determination. A key insight is that the overlap functions 
are governed by the eigenvalues of Casimir operators of reflection 
algebras, revealing an unexpected and powerful algebraic structure.
In this talk I will give an introduction to the problem, review the main 
methods for computing MPS–Bethe state overlaps, and outline several 
applications in integrable quantum systems and holography.

The presentation is based on T. Gombor, Phys. Rev. Lett. 135, 150402.
