Scaling of entanglement entropy and superselection rules
I. Klich, L. S. Levitov
Particle number conservation in fermionic systems restricts the allowed local operations on bi-partite systems. We show how this restriction is related to measurement entropy of pa…
From frustration to glassiness via quantum fluctuations and random tiling with exotic entropy
I. Klich, S. -H. Lee, K. Iida
When magnetic moments (spins) are regularly arranged in a geometry of a triangular motif, the spins may not satisfy simultaneously their interactions with their neighbors. This phe…
Casimir's energy of a conducting sphere and of a dilute dielectric ball
I. Klich
In this paper we sum over the spherical modes appearing in the expression for the Casimir energy of a conducting sphere and of a dielectric ball (assuming the same speed of light i…
Minimal excitation states of electrons in one-dimensional wires
J. Keeling, I. Klich, L. S. Levitov
A strategy is proposed to excite particles from a Fermi sea in a noise-free fashion by electromagnetic pulses with realistic parameters. We show that by using quantized pulses of s…
Supercurrent survival under Rosen-Zener quench of hard core bosons
I. Klich, C. Lannert, G. Refael
We study the survival of super-currents in a system of impenetrable bosons subject to a quantum quench from its critical superfluid phase to an insulating phase. We show that the e…
A thick shell Casimir effect
I. Klich, A. Mann, M. Revzen
We consider the Casimir energy of a thick dielectric-diamagnetic shell under a uniform velocity light condition, as a function of the radii and the permeabilities. We show that the…
