T-odd gluon distribution functions in a spectator model
We present a model calculation of T-odd transverse-momentum-dependent distributions of gluons in the nucleon. The model is based on the assumption...

A model of randomly-coupled Pauli spins
We construct a model of Pauli spin operators with all-to-all 4-local interactions by replacing Majorana fermions in the SYK model with spin...

Transverse Ising Model, Glass and Quantum Annealing
In many physical systems, cooperative interactions between spin-like (two-state) degrees of freedom tend to establish some kind of order in the...

Frame potential of Brownian SYK model of Majorana and Dirac fermions
We consider the Brownian SYK, i.e. a system of N Majorana (Dirac) fermions with a white-noise q -body interaction term. We focus on the dynamics of...

A study of the SYK2 model with twisted boundary conditions
We study a version of the 2-body Sachdev-Ye-Kitaev (SYK 2 ) model whose complex fermions exhibit twisted boundary conditions on the thermal circle. As...

Ground-State Structures of the Ising Model on a Layered Triangular Lattice in a Magnetic Field
AbstractThe magnetic structures of the ground state, as well as magnetic and thermodynamic properties of the antiferromagnetic Ising model on a...

Antiferromagnetic Potts Model on the Body-Centered Cubic Lattice
AbstractWe have studied phase transitions and thermodynamic properties of the antiferromagnetic Potts model with number of spin states q = 3 on a...

Random field Ï•3 model and Parisi-Sourlas supersymmetry
We use the RG framework set up in [
1 ] to explore the Ï• 3 theory with a random field interaction. According to the Parisi-Sourlas conjecture this... -
Course 6: Glasses, Replicas and All That
In these lectures I will review the approach to glasses based on the replica formalism. Many of the physical ideas are very similar to those of older...

Quantum annealing in Sherrington–Kirkpatrick spin glass in presence of time-dependent longitudinal field
Motivated by the recent development of quantum technology using quantum annealing technique and the recent works on the static properties of the...

Beyond islands: a free probabilistic approach
We give a free probabilistic proposal to compute the fine-grained radiation entropy for an arbitrary bulk radiation state, in the context of the...

Phase Transitions and the Magnetic Properties of the Potts Model with Four Spin States on a Hexagonal Lattice in Low Magnetic Fields
Phase transitions and the magnetic properties of the two-dimensional Potts model with the four spin states on a hexagonal lattice in low magnetic...

Annealing and Replica-Symmetry in Deep Boltzmann Machines
In this paper we study the properties of the quenched pressure of a multi-layer spin-glass model (a deep Boltzmann Machine in artificial intelligence...

Spectral form factor in the double-scaled SYK model
In this note we study the spectral form factor in the SYK model in large q limit at infinite temperature. We construct analytic solutions for the...

Euclidean wormholes for individual 2d CFTs
We interpret appropriate families of Euclidean wormhole solutions of AdS 3 gravity in individual 2d CFTs as replica wormholes described by branching...

Symmetry resolution of the computable cross-norm negativity of two disjoint intervals in the massless Dirac field theory
We investigate how entanglement in the mixed state of a quantum field theory can be described using the cross-computable norm or realignment (CCNR)...

Quenched free energy in random matrix model
We compute the quenched free energy in the Gaussian random matrix model by directly evaluating the matrix integral without using the replica trick....

The T2K Flux Calculation Tuned to Replica-Target Data
This chapter presents an extension to the T2K flux calculation framework, accommodating for flux tuning to NA61 measurements with the replica-target....

Statistical Mechanical Theory of Hopfield Model
Hopfield model is a well-known abstract model of associative memory in the brain (Amari in Biolog. cybern. 26:175, 1977 [1]; Hopfield in Proc. Natl....

Entanglement asymmetry in the ordered phase of many-body systems: the Ising field theory
Global symmetries of quantum many-body systems can be spontaneously broken. Whenever this mechanism happens, the ground state is degenerate and one...
