Exact, complete, and universal continuous-time worldline Monte Carlo approach to the statistics of discrete quantum systems
Quantum monte carlo procedures discretization discrete Hilbert space green's function
2014/12/22
We show how the worldline quantum Monte Carlo procedure, which usually relies on an artificial time discretization, can be formulated directly in continuous time, rendering the scheme exact. For an ar...
Ionization-induced asymmetric self-phase modulation and universal modulational instability in gas-filled hollow-core photonic crystal fibers
Ionization-induced asymmetric self-phase modulation universal modulational instability gas-filled hollow-core photonic crystal fibers Optics
2012/4/20
We study theoretically the propagation of relatively long pulses with ionizing intensities in a hollow-core photonic crystal fiber filled with a Raman-inactive gas. Due to photoionization, previously ...

Complete universal quantum gate set fault-tolerant thresholds superconducting qubits
2012/2/27
We use quantum process tomography to characterize a full universal set of all-microwave gates on two superconducting single-frequency single-junction transmon qubits. All extracted gate fidelities, in...
On the universal relations for the formfactors in 1D quantum liquids

2011/9/16
Abstract: For various one-dimensional quantum liquids in the framework of the Luttinger model (bosonization) we establish the relations between the coefficients before the power-law asymptotics of the...
How universal is the Wigner distribution?
Wigner distribution universal Statistical Mechanics
2011/8/17
Abstract: We consider Gaussian ensembles of m N x N complex matrices. We identify an enhanced symmetry in the system and the resultant closed subsector, which is naturally associated with the radial s...
Starting from the universal entropy bounds suggested by Bekenstein and Susskind and applying them to the black-body radiation situation, we get a cut-off of space x ≥ lP with ≥ 0.1. We go further ...
The Universal Arrow of Time III: Gravitation theory
The Universal Arrow of Time III Gravitation theory General Relativity and Quantum Cosmology
2011/8/1
Abstract: The paper is dealing with the analysis of general relativity theory (theory of gravitation) from the point of view of thermodynamic time arrow. Within this framework "informational paradox" ...

2011/9/9
A study of the universal physics for three oriented fermionic dipoles in the hyperspherical adiabatic representation predicts a single long-lived three-dipole state, which exists in only one three-bod...
A new answer to the Needham Question, or Why Galileo didn't discover universal gravitation

2011/9/9
The cultural infrastructure that made possible Galileo’s invention of modern physics is discussed. The brand new element of modern physics is claimed to be firm belief in fundamental structure of the ...

2011/7/28
Abstract: In this paper we consider a sample of a linearly elastic heterogeneous composite in elastodynamic equilibrium and present universal theorems which provide lower bounds for the total elastic ...

2011/7/25
Abstract: We study the 1D extended Hubbard model with a weak repulsive short-range interaction in the non-half-filled band case, using non-perturbative Renormalization Group methods and Ward Identitie...

2010/12/24
In this paper, we quantize universal gauge groups such as SU(\infty), in the sigma-C*-algebra setting. More precisely, we propose a concise definition of sigma-C*-quantum groups and explain the conce...

Universal covers the GW/Kronecker correspondence
2010/12/27
The tropical vertex is an incarnation of mirror symmetry found by Gross, Pandharipande and Siebert. It can be applied to $m$-Kronecker quivers $K(m)$ (together with a result of Reineke) to compute the...
Non-universal shear viscosity from Einstein gravity
Non-universal shear viscosity Einstein gravity
2010/12/24
A very famous result of gauge/gravity duality is the universality of the ratio of shear viscosity to entropy density in every field theory holographically dual to classical, two-derivative (Einstein)...
Statistical physics cannot explain why a thermodynamic arrow of time exists,unless one postulates very special and unnatural initial conditions. Yet, we argue that statistical physics can explain why ...
