Finite Size Scaling of Topological Entanglement Entropy

Yuting Wang, Tobias Gulden, Alex Kamenev

We consider scaling of the entanglement entropy across a topological quantum phase transition in one dimension. The change of the topology manifests itself in a sub-leading term, w…

Sachdev-Ye-Kitaev Model as Liouville Quantum Mechanics

Dmitry Bagrets, Alexander Altland, Alex Kamenev

We show that the proper inclusion of soft reparameterization modes in the Sachdev-Ye-Kitaev model of randomly interacting Majorana fermions reduces its long-time behavior to th…

Topological spin ordering via Chern-Simons superconductivity

Tigran A. Sedrakyan, Victor M. Galitski, Alex Kamenev

We use the Chern-Simons (CS) fermion representation of s =1/2 spin operators to construct topological, long-range magnetically ordered states of interacting two-dimensional (2D) qu…

Dynamical phase transition in large deviation statistics of the Kardar-Parisi-Zhang equation

Michael Janas, Alex Kamenev, Baruch Meerson

We study the short-time behavior of the probability distribution of the surface height in the Kardar-Parisi-Zhang (KPZ) equation in dimension.…

Sinai Diffusion at Quasi-1D Topological Phase Transitions

Dmitry Bagrets, Alexander Altland, Alex Kamenev

We consider critical quantum transport in disordered topological quantum wires at the transition between phases with different topological indexes. Focusing on the example of therm…

Short-time height distribution in 1d KPZ equation: starting from a parabola

Alex Kamenev, Baruch Meerson, Pavel V. Sasorov

We study the probability distribution of the surface height in the Kardar-Parisi-Zhang (KPZ) equation in dimension when starting from a para…
