Landau theory of quenched criticality in linear in-context learning
Daesik Kim, Sumin Choi, Hyojae Jeon +1
In-context learning (ICL) allows a pretrained model to infer a new task from examples supplied in its prompt without updating its parameters. In linear models of ICL, the predictio…

Matrix Product Wave Function of the Ground State and Elementary Excitation in the Spin-1/2 Chain
Jintae Kim, Minsoo Kim, Pramod Padmanabhan +2
We present a variational matrix product state (vMPS) for the ground state of the spin-1/2 Heisenberg model. The MPS effectively organizes the various dimer configurations, in faith…

Path Integral for Spin-1 Chain in the Fluctuating Matrix Product State Basis
Jintae Kim, Rajarshi Pal, Jin-Hong Park +1
A new method of writing down the path integral for spin-1 Heisenberg antiferromagnetic chain is introduced. In place of the conventional coherent state basis that leads to the non-…
