Here is a list of all documented modules with brief descriptions:

Ncontrol	This module handles the calculation of the acceptance ratio. It also monitors the precision of the code, as well as the timing
Ndefault_parameters_generic
Nfields_mod	Handles Hubbard Stratonovitch fields
Nglobal_mod	Handles global updates and parallel tempering
Nhamiltonian	This module defines the Hamiltonian and observables. Here, we have included a set of predefined Hamiltonians. They include the Hubbard and SU(N) tV models on honeycomb, pi-flux and square lattices
Nhamiltonian_main	This module defines the interface between the Hamiltonians (= model and observables definition) and the Monte Carlo core. Hamiltonians are defined as submodules of this module. The Monte Carlo core has only access to public members of this module. For defining a new Hamiltonian named <new_ham_name>, the user has to create the file Hamiltonians/Hamiltonian_<new_ham_name>_smod.F90 and add the line <new_ham_name> to Hamiltonians.list
Nhop_mod	This module computes and stores the exponential of the hopping matrix. It also provide routines to carry out multiplications with \( e^{ - \Delta \tau H_t } = \prod_{n=1}^{N} e^{ - \Delta \tau_n H_t(n) } \), \( e^{ \Delta \tau H_t } = \prod_{n=N}^{1} e^{ \Delta \tau_n H_t(n) } \), \( e^{ - \Delta \tau H_t/2 } = \prod_{n=1}^{N} e^{ - \Delta \tau_n H_t(n)/2 } \), and \( e^{ \Delta \tau H_t/2 } = \prod_{n=N}^{1} e^{ \Delta \tau_n H_t(n)/2 } \). The last equality are important for the symmetric Trotter option. (See variable: Symm in the Hamiltonian module)
Nlattices_interface	C Interface for creating lattice. For use in pyALF
Nlrc_mod	This module handles the long range Coulomb repulsion
Nmpi_shared_memory	This module provides an interface to allocate memory that is shared between different MPI jobs from a single communicator on the same node
Nmymats	Wrappers for linear algebra
Nobservables	This module defines the Obser_Vec and Obser_Latt types and provides routine to initialize them and to print out the bins
Nparse_ham
Nparse_ham_mod
Npredefined_hoppings	This module provides a set of predefined hoppings as well as a general framework to specify the hopping matrix for translation invariant multi-orbital systems
Npredefined_int	This module provides a set of predefined interactions
Npredefined_lattices	This module provides a set of predefined lattices
Npredefined_obs	This module provides a set of predefined observables
Npredefined_trial	This module provides a set of predefined trial wave functions
Nqdrp_mod	This constructs a decompostion Mat = Q D R P^* using a pivoted QR decomposition
Ntau_m_mod	This module handles calculation of imagimary time displaced Green functions and calls the routine ObserT.F90 in the Hamiltonian module, so as to compute the defined time dispalced correlations functions. This modules is for the finite temperature code
Ntau_p_mod	This module handles calculation of imaginary-time-displaced Green functions and calls the routine ObserT.F90 in the Hamiltonian module, so as to compute user defined time-displaced correlations functions. This module is for the projector code
Nudv_state_mod	Handles UDV decompositions
Nudv_wrap_mod	This module contains two version of the stabilization. To switch between the two schemes you should define STAB1 in the set_env.sh file. The defaut scheme is quick and gernerically works better
Nwavefunction_mod	Defines the wavefunction type
Nwrapgr_mod	Handles global updates on a single time slice
