Gauge fields - strings duality and the loop equation
A. Polyakov, V. Rychkov
We explore gauge fields - strings duality by means of the loop equations and the zigzag symmetry. The results are striking and incomplete. Striking - because we find that the strin…
Non-hysteretic branches inside the hysteresis loop in VO2 films for focal plane array imaging bolometers
M. Gurvitch, S. Luryi, A. Polyakov +1
In the resistive phase transition in VO2, temperature excursions from points on the major hysteresis loop produce minor loops. We have found that for sufficiently small excursions…
Fermi-surface topology of the iron pnictide LaFeP
S. Blackburn, B. Prévost, M. Bartkowiak +12
We report on a comprehensive de Haas--van Alphen (dHvA) study of the iron pnictide LaFeP. Our extensive density-functional band-structure calculations can well explain the…
The wall of the cave
A. Polyakov
In this article old and new relations between gauge fields and strings are discussed. We add new arguments that the Yang Mills theories must be described by the non-critical string…
Turbulence without pressure
A. Polyakov
We develop exact field theoretic methods to treat turbulence when the effect of pressure is negligible. We find explicit forms of certain probability distributions, demonstrate tha…
A View From the Island
A. Polyakov
This is a brief and subjective description of ideas which formed our present field-theoretic understanding of fundamental physics.
Perovskite-type cobalt oxide at the multiferroic Co/Pb ZrTiO interface
K. Mohseni, A. Polyakov, H. B. Vasili +13
Magnetic Tunnel Junctions whose basic element consists of two ferromagnetic electrodes separated by an insulating non-magnetic barrier have become intensely studied and used in non…
Magnetic properties of the spin-1 chain compound NiClCHCHCHNH
F. Lipps, A. H. Arkenbout, A. Polyakov +7
We report experimental results of the static magnetization, ESR and NMR spectroscopic measurements of the Ni-hybrid compound NiClCHCHCHNH. In this material…
Velocity and velocity-difference distributions in Burgers turbulence
S. Boldyrev, T. Linde, A. Polyakov
We consider the one-dimensional Burgers equation randomly stirred at large scales by a Gaussian short-time correlated force. Using the method of dissipative anomalies, we obtain ve…
Confining Strings
A. Polyakov
We propose a hypothesis that all gauge theories are equivalent to a certain non-standard string theory. Different gauge groups are accounted for by weights ascribed to the world sh…
String Theory and Quark Confinement
A. Polyakov
This article is based on a talk given at the ``Strings'97'' conference. It discusses the search for the universality class of confining strings. The key ingredients include the loo…
Conformal Turbulence
A. Polyakov
We describe conformal field theories, correlation functions of which satisfy equations of the two-dimensional fluid mechanics. Prediction for the energy spectrum is given, $E(k) \s…
Instability of the topological surface state in BiSe upon deposition of gold
A. Polyakov, C. Tusche, M. Ellguth +10
Momentum resolved photoemission spectroscopy indicates the instability of the Dirac surface state upon deposition of gold on the (0001) surface of the topological insulator BiS…
